Abstract:
Abstract This article deals with the missionary work of the Society of Jesus in today’s Micronesia from the 17th to the 20th century. Although the Jesuit missionaries wanted to reach Japan and other Pacific islands, such as the Palau and Caroline archipelagos, the crown encouraged them to stay in the Marianas until 1769 (when the Society of Jesus was expelled from the Philippines) to evangelize the native Chamorros as well as to reinforce the Spanish presence on the fringes of the Pacific empire. In 1859, a group of Jesuit missionaries returned to the Philippines, but they never officially set foot on the Marianas during the nineteenth century. It was not until the twentieth century that they went back to Micronesia, taking charge of the mission on the Northern Marianas along with the Caroline and Marshall Islands, thus returning to one of the cradles of Jesuit martyrdom in Oceania.

Abstract:
AbstractThe US Department of Defense continues to deploy military assets for disaster relief and humanitarian actions around the world. These missions, carried out through geographically located Combatant Commands, represent an evolving role the US military is taking in health diplomacy, designed to enhance disaster preparedness and response capability. Oceania is a unique case, with most island nations experiencing “acute-on-chronic” environmental stresses defined by acute disaster events on top of the consequences of climate change. In all Pacific Island nation-states and territories, the symptoms of this process are seen in both short- and long-term health concerns and a deteriorating public health infrastructure. These factors tend to build on each other. To date, the US military's response to Oceania primarily has been to provide short-term humanitarian projects as part of Pacific Command humanitarian civic assistance missions, such as the annual Pacific Partnership, without necessarily improving local capacity or leaving behind relevant risk-reduction strategies. This report describes the assessment and implications on public health of large-scale humanitarian missions conducted by the US Navy in Oceania. Future opportunities will require the Department of Defense and its Combatant Commands to show meaningful strategies to implement ongoing, long-term, humanitarian activities that will build sustainable, host nation health system capacity and partnerships. This report recommends a community-centric approach that would better assist island nations in reducing disaster risk throughout the traditional disaster management cycle and defines a potential and crucial role of Department of Defense's assets and resources to be a more meaningful partner in disaster risk reduction and community capacity building.ReavesEJ,TerminiM,BurkleFMJr.Reshaping US Navy Pacific response in mitigating disaster risk in South Pacific Island nations: adopting community-based disaster cycle management.Prehosp Disaster Med.2014;29(1):1-9.

Abstract:
Unmanned aircraft systems (UAS) are important assets for accessing high risk airspace and incorporate technologies for sensor coordination, onboard processing, tele-communication, unconventional flight control, and ground based monitoring and optimization. These capabilities permit adaptive mission management in the face of complex requirements and chaotic external influences. NASA Ames Research Center has led a number of Earth science remote sensing missions directed at the assessment of natural resources and here we describe two resource mapping problems having mission characteristics requiring a mission adaptive capability extensible to other resource assessment challenges. <br><br> One example involves the requirement for careful control over solar angle geometry for passive reflectance measurements. This constraint exists when collecting imaging spectroscopy data over vegetation for time series analysis or for the coastal ocean where solar angle combines with sea state to produce surface glint that can obscure the signal. Furthermore, the primary flight control imperative to minimize tracking error should compromise with the requirement to minimize aircraft motion artifacts in the spatial measurement distribution. A second example involves mapping of natural resources in the Earth’s crust using precision magnetometry. In this case the vehicle flight path must be oriented to optimize magnetic flux gradients over a spatial domain having continually emerging features, while optimizing the efficiency of the spatial mapping task. <br><br> These requirements were highlighted in recent Earth Science missions including the OCEANIA mission directed at improving the capability for spectral and radiometric reflectance measurements in the coastal ocean, and the Surprise Valley Mission directed at mapping sub-surface mineral composition and faults, using high-sensitivity magnetometry. This paper reports the development of specific aircraft control approaches to incorporate the unusual and demanding requirements to manage solar angle, aircraft attitude and flight path orientation, and efficient (directly geo-rectified) surface and sub-surface mapping, including the near-time optimization of these sometimes competing requirements.

Abstract:
In the nineteenth century, François Libermann, a converted Jew who became a priest, is attracted by the ministry to the Black people of the French Colonies and Africa. Having obtained a mission site in Guinea, he sent his first vicar apostolic, Benoît Truffet, who set up the beginnings of a pedagogy of Pauline evangelization, according to the will of Libermann. In 1930, about eighty years later, the Directory for Missions, under the leadership of Bishop Alexandre Le Roy, was an indispensable summary of missionary teaching methods developed by the Holy Ghost Fathers in Africa. After analyzing it, we outline a two-step process. The first step is that of the Pauline insertion, “all in all” marked by kenosis, learning of indigenous languages and the insertion of the missionary in local life. The second step is that of inculturation which consists in making use of the culture as a vehicle for the new faith, then in practising a hermeneutics of cosmogonies and finally in establishing a suitable pastoral approach which should lead to the emergence of a native clergy. This process corresponds to that applied in Oceania.

Abstract:
This article demonstrates historically and statistically that conversionary Protestants (CPs) heavily influenced the rise and spread of stable democracy around the world. It argues that CPs were a crucial catalyst initiating the development and spread of religious liberty, mass education, mass printing, newspapers, voluntary organizations, and colonial reforms, thereby creating the conditions that made stable democracy more likely. Statistically, the historic prevalence of Protestant missionaries explains about half the variation in democracy in Africa, Asia, Latin America and Oceania and removes the impact of most variables that dominate current statistical research about democracy. The association between Protestant missions and democracy is consistent in different continents and subsamples, and it is robust to more than 50 controls and to instrumental variable analyses.

Abstract:
AbstractConventional altimetry measures a one-dimensional profile of sea surface height (SSH) along the satellite track. Two-dimensional SSH can be reconstructed using mapping techniques; however, the spatial resolution is quite coarse even when data from several altimeters are analyzed. A new satellite mission based on radar interferometry is scheduled to be launched in 2020. This mission, called Surface Water and Ocean Topography (SWOT), will measure SSH at high resolution along a wide swath, thus providing two-dimensional images of the ocean surface topography. This new capability will provide a large amount of data even though they are contaminated with instrument noise and geophysical errors. This paper presents a tool that simulates synthetic observations of SSH from the future SWOT mission using SSH from any ocean general circulation model (OGCM). SWOT-like data have been generated from a high-resolution model and analyzed to investigate the sampling and accuracy characteristics of the future SWOT data. This tool will help explore new ideas and methods for optimizing the retrieval of information from future SWOT missions.

Abstract:
Abstract Missional hermeneutics is a relatively recent development in the field of biblical hermeneutics, emerging from several decades of scholarly engagement with the concept and frame of missio Dei. In a key recent publication in the field, Reading the Bible Missionally, edited by Michael Goheen, the voices of the Global South and of women – and certainly of women from Oceania – do not feature. In this article the authors, both Oceanic women, interrupt the discourse to read biblical text from their twice-under perspective. The Beatitudes provide the frame and the lens for a spiralling discussion of the missio Dei as, to borrow from Letty M. Russell, “calculated inefficiency.” Stories of faithful Oceanic women interweave with those of God and of biblical women, offering their complexities to challenge assumptions and simplicities.

Abstract:
When Catholic Missionaries first went to Western Oceania in the 1840s, they encountered established Protestant mission stations and worshipping Christian communities. The first Vicar Apostolic of Western Oceania, instructed his missionaries to present their church as “the ancient Church, the mother Church, the foundation Church, the true and only Church, which exists everywhere on earth.” The diocesan archives in Auckland New Zealand preserve a single copy of a poster which communicated those ideas. This article identifies the source of that visual aid which was widely used in the first thirty years of the Catholic Mission to Western Oceania.

Abstract:
A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting plumes and assessing their mixing in the near and far-fields. Unique to this study is the measurement of Colored Dissolved Organic Matter (CDOM) in the discharge plume and its application for quantitative estimates of the plume's dilution. AUV mission planning methodologies for discharge plume sampling, plume characterization using onboard optical sensors, and comparison of observational data to model results are presented. The results suggest that even under variable oceanic conditions, properly planned missions for AUVs equipped with an optical CDOM sensor in addition to traditional oceanographic sensors, can accurately characterize and track ocean outfall plumes at higher resolutions than cast-based techniques.

Full text
Abstract:
Linguistic research showing dependence on context in deriving language meaning discloses the integral linking of the Luo language with their departed ancestors and the upholding of customary laws. Meaning and impact being transformed in the process of translation from one context to another explains the severe limitations found in previous attempts at cross-cultural understanding between Western and Luo (African) peoples. Studying Luo people’s understanding of ‘bad’ in the light of the above reveals much that often remains invisible to Westerners. ‘Bad’ arises from the activities of ghosts acting through people’s hearts often as a result of breaking taboos. Cleansing, especially of ghosts, through prayer, keeping customary laws and salvation are used to counteract such ‘bad’. Conventional Biblical and mission hermeneutics are, in failing to account for pragmatic linguistics, found seriously wanting. Forces and powers being spiritually based in a monistic worldview amongst the Luo render clear cross-cultural communication with a rationalist and monotheist West impossible. Theological education based on African languages is advocated as the way to engage the challenges of Christianity with Luo ways of life in a way that will result in a deeply rooted African church, and a moral, vibrant, intellectually and economically active African society.

Abstract:
L’oceanografia per satèl•lit ha esdevingut una integració consolidada de les tècniques convencionals de monitorització in situ dels oceans. Un coneixement precís dels processos oceanogràfics i de la seva interacció és fonamental per tal d’entendre el sistema climàtic. En aquest context, els camps de salinitat mesurats regularment constituiran directament una ajuda per a la caracterització de les variacions de la circulació oceànica global. La salinitat s’utilitza en models oceanogràfics predictius, pero a hores d’ara no és possible mesurar-la directament i de forma global. La missió Soil Moisture and Ocean Salinity (SMOS) (en català, humitat del sòl i salinitat de l’oceà) de l’Agència Espacial Europea pretén omplir aquest buit mitjançant la implementació d’un satèl•lit capaç de proveir aquesta informació sinòpticament i regular. Un nou instrument, el Microwave Imaging Radiometer by Aperture Synthesis (MIRAS) (en català, radiòmetre d’observació per microones per síntesi d’obertura), ha estat desenvolupat per tal d’observar la salinitat de la superfície del mar (SSS) als oceans a través de l’adquisició d’imatges de la radiació de microones emesa al voltant de la freqüència de 1.4 GHz (banda L). SMOS portarà el primer radiòmetre orbital, d’òrbita polar, interferomètric 2D i es llençarà a principis de 2009. Així com a qualsevol altra estimació de paràmetres geofísics per teledetecció, la recuperació de la salinitat és un problema invers que implica la minimització d’una funció de cost. Per tal d’assegurar una estimació fiable d’aquesta variable, la resta de paràmetres que afecten a la temperatura de brillantor mesurada s’ha de tenir en compte, filtrar o quantificar. El producte recuperat seran doncs els mapes de salinitat per a cada passada del satèl•lit sobre la Terra. El requeriment de precisió proposat per a la missió és de 0.1 ‰ després de fer el promig en finestres espaciotemporals de 10 dies i de 20x20. En aquesta tesi de doctorat, diversos estudis s’han dut a terme per a la determinació del balanç d’error de la salinitat de l’oceà en el marc de la missió SMOS. Les motivacions de la missió, les condicions de mesura i els conceptes bàsics de radiometria per microones es descriuen conjuntament amb les principals característiques de la recuperació de la salinitat. Els aspectes de la recuperació de la salinitat que tenen una influència crítica en el procés d’inversió són: • El biaix depenent de l’escena en les mesures simulades, • La sensibilitat radiomètrica (soroll termal) i la precisió radiomètrica, • La definició de la modelització directa banda L • Dades auxiliars, temperatura de la superfície del mar (SST) i velocitat del vent, incerteses, • Restriccions en la funció de cost, particularment en el terme de salinitat, i • Promig espacio-temporal adequat. Un concepte emergeix directament de l’enunciat del problema de recuperació de la salinitat: diferents ajustos de l’algoritme de minimització donen resultats diferents i això s’ha de tenir en compte. Basant-se en aquesta consideració, la determinació del balanç d’error s’ha aproximat progressivament tot avaluant l’extensió de l’impacte de les diferents variables, així com la parametrització en termes d’error de salinitat. S’ha estudiat l’impacte de diverses dades auxiliars provinents de fonts diferents sobre l’error SSS final. Això permet tenir una primera impressió de l’error quantitatiu que pot esperar-se en les mesures reals futures, mentre que, en un altre estudi, s’ha investigat la possibilitat d’utilitzar senyals derivats de la reflectometria per tal de corregir les incerteses de l’estat del mar en el context SMOS. El nucli d’aquest treball el constitueix el Balanç d’Error SSS total. S’han identificat de forma consistent les fonts d’error i s’han analitzat els efectes corresponents en termes de l’error SSS mig en diferents configuracions d’algoritmes. Per una altra banda, es mostren els resultats d’un estudi de la variabilitat horitzontal de la salinitat, dut a terme utilitzant dades d’entrada amb una resolució espacial variable creixent. Això hauria de permetre confirmar la capacitat de la SSS recuperada per tal reproduir característiques oceanogràfiques mesoscàliques. Els principals resultats i consideracions derivats d’aquest estudi contribuiran a la definició de les bases de l’algoritme de recuperació de la salinitat.
Satellite oceanography has become a consolidated integration of conventional in situ monitoring of the oceans. Accurate knowledge of the oceanographic processes and their interaction is crucial for the understanding of the climate system. In this framework, routinely-measured salinity fields will directly aid in characterizing the variations of the global ocean circulation. Salinity is used in predictive oceanographic models, but no capability exists to date to measure it directly and globally. The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission aims at filling this gap through the implementation of a satellite that has the potential to provide synoptically and routinely this information. A novel instrument, the Microwave Imaging Radiometer by Aperture Synthesis, has been developed to observe the sea surface salinity (SSS) over the oceans by capturing images of the emitted microwave radiation around the frequency of 1.4 GHz (L-band). SMOS will carry the first-ever, polar-orbiting, space-borne, 2-D interferometric radiometer and will be launched in early 2009. Like whatsoever remotely-sensed geophysical parameter estimation, the retrieval of salinity is an inverse problem that involves the minimization of a cost function. In order to ensure a reliable estimation of this variable, all the other parameters affecting the measured brightness temperature will have to be taken into account, filtered or quantified. The overall retrieved product will thus be salinity maps in a single satellite overpass over the Earth. The proposed accuracy requirement for the mission is specified as 0.1 ‰ after averaging in a 10-day and 2ºx2º spatio-temporal boxes. In this Ph.D. Thesis several studies have been performed towards the determination of an ocean salinity error budget within the SMOS mission. The motivations of the mission, the rationale of the measurements and the basic concepts of microwave radiometry have been described along with the salinity retrieval main features. The salinity retrieval issues whose influence is critical in the inversion procedure are: • Scene-dependent bias in the simulated measurements, • Radiometric sensitivity (thermal noise) and radiometric accuracy, • L-band forward modeling definition, • Auxiliary data, sea surface temperature (SST) and wind speed, uncertainties, • Constraints in the cost function, especially on salinity term, and • Adequate spatio-temporal averaging. A straightforward concept stems from the statement of the salinity retrieval problem: different tuning and setting of the minimization algorithm lead to different results, and complete awareness of that should be assumed. Based on this consideration, the error budget determination has been progressively approached by evaluating the extent of the impact of different variables and parameterizations in terms of salinity error. The impact of several multi-sources auxiliary data on the final SSS error has been addressed. This gives a first feeling of the quantitative error that should be expected in real upcoming measurements, whilst, in another study, the potential use of reflectometry-derived signals to correct for sea state uncertainty in the SMOS context has been investigated. The core of the work concerned the overall SSS Error Budget. The error sources are consistently binned and the corresponding effects in terms of the averaged SSS error have been addressed in different algorithm configurations. Furthermore, the results of a salinity horizontal variability study, performed by using input data at increasingly variable spatial resolution, are shown. This should assess the capability of retrieved SSS to reproduce mesoscale oceanographic features. Main results and insights deriving from these studies will contribute to the definition of the salinity retrieval algorithm baseline.

Abstract:
Les précipitations résultent d'un phénomène atmosphérique caractérisé par une variabilité spatiale et temporelle forte. Cette variabilité dans la distribution des pluies et des évènements intenses a des impacts en hydrologie de surface variés selon les régions du monde. Toute modification du climat tropical est associée à une modification du cycle de l'eau et de l'énergie dans ces régions. Dans un contexte de changement climatique, il est donc important de développer des outils permettant d'estimer quantitativement les précipitations, à l'échelle du globe, à la fois sur les surfaces continentales et les surfaces océaniques. Les travaux présentés dans cette thèse s'intéressent à l'observation des précipitations depuis l'espace. En effet, la mesure des pluies nécessite une densité d'observations élevée qui, sur l'ensemble des Tropiques, n'est accessible qu'à partir d'observations spatiales. Depuis plusieurs décades, les moyens satellitaires à disposition ont beaucoup évolué et offrent aujourd'hui une densité d'observations de plus en plus fortes. Grâce aux nouvelles missions déployées telles que Megha-Tropiques au sein de la future constellation GPM (Global Precipitation Measurement), on a accès à un ensemble de systèmes d'observations qui amène à une densité accrue d'observations spatiales. L'estimation quantitative des précipitations n'était possible qu'à l'échelle mensuelle, il est maintenant envisageable d'estimer la pluie par satellite à des échelles de temps de plus en plus fines. Cette thèse s'intéresse aux échelles 1 ̊/1-jour, échelle clé pour les études météorologiques et hydrologiques. Il existe un large spectre de méthodes d'estimation de précipitations par satellite, de qualité inégale. Dans un premier temps, une analyse des produits issus des développements les plus récents montre que leur qualité a atteint un degré suffisant pour être utilisé de manière quantitative aux échelles de temps pertinentes en météorologie. Il apparaît également qu'à ces échelles de temps, il est nécessaire d'utiliser les estimations de cumuls de précipitations conjointement avec leurs barres d'erreurs. Une nouvelle méthode d'estimations de précipitations sur l'ensemble de la ceinture tropicale, appelée TAPEER (Tropical Amount of Precipitation with an Estimate of ERrors), est donc développée dans le but d'estimer des cumuls de pluie et leurs erreurs associées à l'échelle 1 ̊/1-jour. Cette approche est fondée sur une méthode de fusion de données de l'imagerie Infrarouge d'une constellation de satellites géostationnaires et d'estimations de taux de pluie issues de radiomètres Micro-ondes d'une constellation de satellites défilant. Des techniques de modélisations sont mises en oeuvre afin d'associer une erreur aux cumuls de pluie produits. Une investigation détaillée du bilan d'erreur de la méthode TAPEER montre que les sources principales d'incertitudes sont liées à l'échantillonnage et aux biais systématiques sur les taux de pluie d'intensité moyenne. Une étude sur l'été 2009 révèle l'importance de l'utilisation de la barre d'erreur dans l'analyse de la distribution des pluies, en particulier pour les plus forts cumuls sur la ceinture tropicale.

Abstract:
AbstractThe oceanic islands of the Gulf of Guinea (Príncipe, São Tomé, and Annobón) have been the focus of biological research for over two hundred years. Following small surveys that generated modest collections in the eighteenth and early mid-nineteenth century, European institutions commissioned several exploratory missions to the region that resulted in the first major catalogues of its biodiversity. The following century brought a new wave of research investment, mostly driven by the colonial interests. After the independence of both Equatorial Guinea and São Tomé and Príncipe, novel research trends focusing on conservation aspects of biodiversity research emerged. Here we present a chronological review of the zoological and botanical expeditions to the region, commenting on their major results, collectors, and the naturalists who studied them.

Abstract:
Camera systems used for deep-sea video missions require mechanical housings, which can withstand the immense pressures of the ocean. These housings are generally pressurized-air canisters. The size, weight and cost of these housings increase rapidly with the ocean depth of the mission. The risk of catastrophic implosion and resulting bodily harm to divers also increases with depth. This paper presents a liquid-filled camera system which reduces these risks and limitations by eliminating the need for such air-filled housings in a novel lens design.

Abstract:
Abstract As oceans cover over 70% of the planet’s surface, they represent a large reservoir of resources that remained vastly untapped. Unmanned Underwater Vehicles (UUVs) are becoming key technology for ocean exploration. Ocean thermal gradient is a permanent and reliable energy source that can be used to power UUVs using phase change material (PCM)-based thermal engines. When using PCM-based thermal engines to power UUVs, there are different energy conversion stages, thermal, hydraulic, kinetic, and electrical, dependent on a wide variety of parameters. Thus, optimization of the overall energy conversion is still a challenge for powering the increasing energy demanding UUVs for long missions. The goal of this study is to propose a PCM-based ocean thermal energy harvesting system for powering float type UUVs such as the Solo II float. This reduces the cost for battery replacement and expands the float’s mission time. For this purpose, we developed a model consisting of hydraulic and electrical systems, designed to provide the electrical power needed by the UUV. The hydraulic and electrical systems are implemented using MATLAB-Simulink. The model developed can provide 13.66 kJ of electrical energy, which is more than 1.5 times the energy requirement per cycle for the SOLO II float.

Abstract:
The paper provides considerations for a novel unmanned underwater vehicle class that offers new options to the offshore industries and marine science in matters of endurance, payload capacity, development time and economic viability. Today, different mission scenarios require different underwater vehicles. By applying modularization approach to the development of modular product classes, another way to design such vehicles is shown. Radical modularization of the vehicle enables collaborative as well as independent development of payload modules by industry or science. The design idea allows the combination of proven basic modules with novel mission modules. This allows assigning development activities of mission modules to diverse 3rd-party developers or customers. Topics covered in this paper are related to potential missions and the requirements they make on the vehicle. An evaluation of application scenarios considering the technical challenges vs. their economical relevance is made. The requirements for the MUM system are identified by analyzing the mission procedures regarding specific scenarios. The modular design method and challenges to validate feasibility of an extreme number of possible vehicle variants follow. Examples of variant drivers like diving depth or vehicle range as well as possible solutions will be discussed. The topics covered are the basis for further work within the three year research project MUM – Large Modifiable Underwater Mothership.

Abstract:
Earth Observation (EO) is key for climate and environmental monitoring at global level, and in specific regions where the effects of global warming are more noticeable, such as in polar regions, where ice melt is also opening new commercial maritime routes. Soil moisture is also useful for agriculture and monitoring the advance of desertification, as well as biomass and carbon storage. Global Navigation Satellite System - Reflectometry (GNSS-R) and L-band microwave Radiometry are passive microwave remote sensing techniques that can be used to perform these types of measurements regardless of the illumination and cloud conditions, and -since they are passive- they are well suited for small satellites, where power availability is a limiting factor. GNSS-R was tested from space onboard the UK-DMC and the UK TechDemoSat-1, and several missions have been launched using GNSS-R as main instrument, as CyGNSS, BuFeng-1, or the FSSCAT [1] mission. These missions aim at providing soil moisture [2], ocean wind speed [3], and flooding mapping of the Earth. L-band microwave radiometry data has also been retrieved from space with SMOS and SMAP missions, obtaining sea ice thickness, soil moisture, and ocean salinity data [4]. The 3Cat-4 mission was selected by the ESA Academy "Fly your Satellite" program in 2017. It aims at combining both GNSS-R and L-band Microwave Radiometry at in a low-power and cost-effective 1-Unit (1U) satellite. Moreover, the 3Cat-4 can also detect Automatic Identification System (AIS) signals from vessels. The single payload is the Flexible Microwave Payload 1 (FMPL-1) [5] that performs the signal conditioning and signal processing for GNSS-R, L-Band microwave radiometry and AIS experiments. The spacecraft has three payload antennas: (1) a VHF monopole for AIS signals; (2) an uplooking antenna for the direct GPS signals; (3) a downlooking antenna that captures reflected GPS signals, and for the Microwave Radiometer. The downlooking antenna is a deployable helix antenna called the Nadir Antenna and Deployment Subsystem (NADS) which has a volume of less than 0,3U when stowed, achieving an axial length of more than 500 mm when deployed. As part of this mission, the design of the NADS antenna, its RF performance, as well as the environmental tests performed in terms of structural and thermal space conditions will be presented.

Abstract:
A novel triadic suite of flight technologies is introduced by developing, articulating and integrating ground-effect, free amphibian flight and orbital flight capabilities into a triadic system-of-systems able to seamlessly operate across all three mobility paradigms. The triad is then implemented onto our new purpose-designed hydro-aerospace vehicle, propelled by latest-generation micro-reactors for industry-leading aerospace thrust, whilst providing long-range carbon-free flight mobility and autonomy. The vehicle structure and materials are further optimized for a seamless switch between standard and stealth operations, while also providing structural robustness and functional flexibility to safely carry and deploy heavy and highly reactive payloads. The robustness and versatility of the new vehicle is demonstrated across a suite of challenging oceanic and aerospace theaters of operation. Special emphasis is given to search and rescue missions, along with surveillance and security operations involving multidomain flight segments and highlighting seamless cross-domain transitions.

Abstract:
As part of the US Army Corps of Engineers’ mission to evaluate and move dredged material (DM) to maintain navigation channels, environmental evaluation of the prospective material is required by the Code of Federal Regulations. While existing guidance manuals provide useful guidance to DM regulators, they are over 30 years old and not reflective of the latest science. However, efforts to update procedures and publish the documents individually or as a combined dredging manual have been thus far unsuccessful. These issues, coupled with a lack of consistent reporting and decision documentation, lead to delays arising from challenges addressing project-specific issues not clearly covered within the existing guidance, revisiting previously resolved issues or negotiating disputes between permitting authorities. This technical report provides a path toward modernization of the environmental compliance aspects of DM evaluation guidance in part through software executables guiding the management and decision process and through a structured, evidence-based approach. The value added is an updated approach to DM testing and evaluation decisions.

Abstract:
The aim of the WP3 “Network Integration and Improvements” is to coordinate and enhance key aspects of integration of European observing technology (and related data flows) for its use in the context of international ocean monitoring activities. One of the dimensions of the integrations is the constitution of thematic networks, that is, networks whose aim is to address specific observational challenges and thus to favor innovation, innovation that will ultimately support the Blue economy. In this context, the specific aim of Task 3.8 is to accelerate the adoption of molecular methods such as genomic, transcriptomic (and related “omics”) approaches, currently used as monitoring tools in human health, to the assessment of the state and change of marine ecosystems. It was designed to favor the increase the capacity to evaluate biological diversity and the organismal metabolic states in different environmental conditions by the development of “augmented observatories”, utilizing state-of-art methodologies in genomic-enabled research at multidisciplinary observatories at well-established marine LTERs, with main focus on a mature oceanographic observatory in Naples, NEREA. In addition, an effort is dedicated to connecting existing observatories that intend to augment their observations with molecular tools. Molecular approaches come with many different options for the protocols (size fractioning, sample collection and storage, sequencing etc). One main challenge in systematically implementing those approaches is thus their standardization across observatories. Based on a survey of existing methods and on a 3-year experience in collecting, sequencing and analyzing molecular data, this deliverable is thus dedicated to present the SOPs implemented and tested at NEREA. The SOPs consider a size fractioning of the biological material to avoid biases toward more abundant, smaller organisms such as bacteria. They cover both the highly stable DNA and the less stable RNA and they are essentially an evolution of the ones developed for the highly successful Tara Oceans Expedition and recently updated for the Expedition Mission Microbiomes, an All-Atlantic expedition organised and executed by the EU AtlantECO project. Importantly, they have only slight variations with respect the ones adopted by the network of genomic observatories EMOBON. Discussions are ongoing with EMOBON to perfectly align the protocols. The SOPs are being disseminated via the main national and international networks. (EuroSea Deliverable, D3.19)

Abstract:
The amount of carbon dioxide that the ocean can absorb without becoming highly acidic depends on the alkalinity of its surface water. This term refers to the amount of acid-binding mineral components that were previously dissolved from weathered rock and washed into the ocean. The question now is: could a targeted input of such minerals help to increase the marine carbon dioxide uptake without unbalancing the chemistry and life in the ocean? This approach does work in simple model calculations. However, field experiments are still lacking, as are realistic simulations and detailed knowledge about the consequences and risks of an increase in alkalinity. The research mission CDRmare investigates the potentials, feasibility and side effects of the various methods.

A deep-sea experiment on carbon dioxide storage in oceanic crust. CDRmare, 2022. http://dx.doi.org/10.3289/cdrmare.21.

Full text
Abstract:
On Iceland, water enriched with carbon dioxide has been injected into the upper ocean crust since 2014 – and successfully. The carbon dioxide mineralises within a short time and is firmly bound for millions of years. However, since ocean crust only rises above sea level in a few places on Earth, researchers currently investigate the option of injecting carbon dioxide into ocean regions where huge areas of suitable basalt crust lie at medium to great water depths. One possible advantage: In the deep sea subsurface, the carbon dioxide would either be stable as a liquid or dissolve in the seawater circulating in the rock. Due to the high pressure, both the liquid carbon dioxide and the carbon dioxide-water mixture would be heavier than seawater, making leakage from the underground unlikely. But would carbon dioxide storage in the deep sea subsurface be technically feasible and ultimately also economically viable? The research mission CDRmare provides answers – with the help of the world's first deep-sea research experiment on carbon dioxide storage on cooled flanks of the Mid-Atlantic Ridge.

Abstract:
Algae, zooplankton and fish are among the key players in the biological carbon pump that allows the ocean to naturally remove carbon dioxide from the atmosphere and store it at great depths. However, for this mechanism to function optimally, it needs nutrients, which are lacking in many places, at least in the light-flooded surface water. By pumping up nutrient-rich deep water, humans could remedy this nutrient deficiency. But whether artificial upwelling would actually have an effect on the climate, what risks it would entail and whether it could be technically and legally implemented on a large scale, is still uncertain.
