Abstract:

It is perhaps appropriate, on this the exact 187th anniversary of the death of Admiral Lord Nelson at Trafalgar and in the year in which so many celebrations have taken place to commemorate the 500th anniversary of Christopher Columbus's arrival somewhere in the West Indies, to consider the progress which has been made towards international co-operation and achievements in hydrographic surveying and nautical cartography, particularly since the formation of the International Hydrographic Bureau in 1921, and to look at the problems facing international hydrography in the immediate future.

Abstract:

The analysis and solution of most beach erosion problems are based to a significant degree on the quantitative changes in the bottom hydrography as observed in successive surveys. Critical decisions as to the dominant direction of littoral drift, the average rate of this drift, and the onshore-offshore movement of material are based largely on such hydrographic surveys. As the net changes between successive surveys are usually small compared to the area being studied, the degree of accuracy or comparability of the hydrographic surveys is of considerable importance. For instance, a net change of 100,000 cubic yards over one square mile of beach represents an average change in depth of only about 0.1 feet. Thus, it can be seen that uncompensated errors in depth measurement of as little as 0.1 feet can produce indications of significant littoral sand movement which might not exist in reality.

Abstract:

After Global Navigation Satellite Systems (GNSS) were first used in the field of hydrography in 1980, developments in hydrographic surveying accelerated. Survey precision in hydrography has been improved for both horizontal and vertical positioning and seafloor acoustic measurement by means of these new developments. Differential Global Positioning System (DGPS), Real Time Kinematic (RTK) and Network RTK (NRTK) techniques are the satellite-based positioning techniques that are commonly used in shallow water surveys and shoreline measurements. In line with these developments, the newer Precise Point Positioning (PPP) has been introduced. Combining precise satellite positions and clocks with dual-frequency GNSS data, PPP can provide position solutions from the centimetre to decimetre level. In this study, the coordinates of control points were determined by using the Post-Process PPP (PP-PPP) technique. Seven test points, which are the points of the Continuously Operating Reference Station - Turkey (CORS-TR) network, are selected near the shorelines within Turkey. The 24-hour data was split from one to six hours by one hour periods. Automatic Point Positioning Service (APPS) was selected to process the data. The poisoning error of the test points were given and compared with International Hydrographic Organization (IHO) S44 hydrographic survey standards.

Abstract:

In the 1830s and 1840s, the Hydrographic Office of the British Admiralty developed and oversaw one of the major state-run surveying projects of the nineteenth century. This involved a range of instruments whose circulation was increasingly regulated. Using extant museum collections and the correspondence of those involved, this article explores how such objects can be used to discuss both bureaucratic organization at a time of expanding government and the complex issues of sociability involved in hydrographic surveying. Surveying officers worked in a context in which the propriety of property on public service was a pervasive question. Instruments might be given as gifts between officers, appropriated as recompense, absorbed as state property, and disputed between friends. The ownership, provision, and treatment of instruments in particular could be used to demonstrate an officer’s peculiar zeal or institutional neglect. To those outside the ship, what was understood as over-instrumentation became amusing spectacle. On board, their use was part of a deeply hierarchical order of work in regions of colonial and mercantile importance. In examining the relationships around these instruments of survey, the paper proposes a richer understanding of the material culture of hydrography in the early nineteenth century.

Abstract:

The International Hydrographic Organization (IHO) has issued standards that provide the minimum requirements for different types of hydrographic surveys execution to collect data to be used to compile navigational charts. Such standards are usually updated from time to time to reflect new survey techniques and practices and must be achieved to assure both surface navigation safety and marine environment protection. Hydrographic surveys can be classified to four orders namely, special order, order 1a, order 1b, and order 2. The order of hydrographic surveys to use should be determined in accordance with the importance to the safety of navigation in the surveyed area. Typically, geodetic-grade dual-frequency GPS receivers are utilized for position determination during data collection in hydrographic surveys. However, with the evolution of high-sensitivity low-cost single-frequency receivers, it is very important to evaluate the performance of such receivers. This paper investigates the performance of low-cost single-frequency GPS receivers in hydrographic surveying applications. The main objective is to examine whether low-cost single-frequency receivers fulfil the IHO standards for hydrographic surveys. It is shown that the low-cost single-frequency receivers meet the IHO horizontal accuracy for all hydrographic surveys orders at any depth. However, the single-frequency receivers meet only order 2 requirements for vertical accuracy at depth more than or equal 100&thinsp;m.

Abstract:

A traditional shore-based discrete point chart datum (CD) that represents the lowest astronomical tide (LAT) in Saudi Arabia using tide gauge data is utilized to reduce the observed depth collected from hydrographic surveying test to CD-referenced depth for producing navigation charts for maritime navigation applications. A need for developing CD in a continuous form is essential to replace the traditional discrete CD using tide gauge data. The importance of the development of CD-to-ellipsoid (WGS84) separation model is that it can be utilized by the hydrographers to develop an accurate vertical control for hydrographic surveys applications and can be utilized by the mariners to produce accurate dynamic electronic navigation charts (ENCs). In this paper, a continuous CD to WGS84 ellipsoid separation model for the Sharm Obhur area is developed using a multibeam hydrographic surveying test. It is shown that the continuous chart datum ranges from −4.920 m to −4.766 m and can be achieved with standard deviation ranges from 0.1 cm to 2.3 cm. To validate the separation model, a comparison was made with the gravimetric/oceanographic method based on the separation height developed from geoid height, the sea surface topography and LAT value (chart datum to mean sea level) at the tide gauge located in the study area. The comparison showed that the average value of the developed continuous CD to WGS84 separation model heights using multibeam hydrographic surveying agrees with the separation height estimated from gravimetric/oceanographic method.

Abstract:

Airborne lidar bathymetry (ALB) is a method used to survey and map coastal and littoral zones. Along with extracting seafloor depth and reflectance in the surveyed area, a fundamental requirement of these surveys is to detect underwater targets, hazards, or obstructions. The ability to detect underwater targets depends on a target's dimensions and reflectance, the depth and turbidity of the water, system and survey configuration, data processing capabilities, and algorithmic sophistication. Understanding the effects of each of these factors on the performance of underwater target detection is essential in determining the target detection capabilities of a proposed ALB system. After detailing the development of a simulation environment to model received ALB system waveforms, this work explores the theoretical target detection capabilities of an ALB system.

Abstract:

The kinematic wave model for overland and channel flow is used to develop a method to calculate the runoff hydrograph from a watershed consisting of a cascade of planes and channels. First, a general, semi-analytic solution based on the method of characteristics and incorporating flow on infiltrating surfaces is derived. Unrealistic properties of previous solutions based on the method of characteristics are avoided by defining lateral inflow in relation to the presence or absence of flowing water on the flow surface. It is shown that the new definition of lateral inflow results in both a more physically realistic representation of the overland and channel flow process during the recession stage of the hydrograph and a more accurate estimation of runoff volume than obtained by previous solutions. Second, the concept of the storage of water at kinematic equilibrium is used to calculate a depth-discharge coefficient for a single plane system and a two plane, one channel system, each of which is hydraulically equivalent to a complex cascade of planes and channels. The method is validated on two rangeland watersheds in Arizona. The results show that hydrographs generated from the two simplified watershed geometries are essentially the same as those from complex geometries when the duration of the runoff event is equal to or greater than the time to kinematic equilibrium. At durations less than the time to kinematic equilibrium, the two plane, one channel system preserves the complex geometry properties better than the single plane system.

Abstract:

This report gives suggestions to sub-Saharan Africa regarding the implementation of the International Hydrographic Organisation's (IHO) Worldwide Electronic Navigational Chart Data Base (WEND) for Electronic Chart Display and Information _systems (ECDIS). The IHO, recognising the need to supply up-to-date navigational information to mariners at sea, proposes the establishment of a worldwide network of navigational information. This proposal is aimed at addressing the information needs of international shipping. However, it does not restrict any hydrographic office from developing its own data base for national shipping. ECDIS is one new technology that will improve safety at sea. It integrates the Electronic Navigational Chart (ENC) and other navigational information. Unlike the paper chart, ECDIS will select and display information that is needed at any chosen moment thereby removing clutter from the display. The mariner will only see the information that is relevant for his immediate decision-making. ECDIS is versatile, complex and a potentially important aid to navigation decision-making. It enables mariners to navigate under conditions of poor visibility and through narrow and poorly-marked channels. It has the power to process data from a variety of sources and to detect and graphically show relationships between the data. Since history requires us to look at the past and the present to be able to project into the future, the report begins by giving the background to electronic charts. The report examines the traditional paper chart and the present method of updating the chart. It looks at the information contained in the Notices to Mariners, Radio Navigational Warnings and Global Maritime Distress and Safety Systems. The responsibilities and obligations of the various professional disciplines involved in updating the paper chart are also discussed. The limitations of the paper chart are commented upon and the need for a new technology is emphasized. The procedure for updating the electronic chart is also discussed. The terms "paper chart" and "traditional paper chart" are used interchangeably and mean the same thing in this report. The second chapter examines the requirements of ECDIS. It discusses the user requirements and the minimum system configuration. Operational and performance requirements are also examined. Chapter Three discusses the Worldwide Electronic Navigational Chart Data Base (WEND). It gives a brief background to WEND and discusses the conceptual model of the organisation of WEND on regional bases. It examines a paper presented by Australia in relation to a single state WEND proposed by Norway. Since the whole process of networking the navigational information depends on technology, an in-depth treatment of the subject is carried out in Chapter Four. Issues discussed include networking and distributed system, standards and protocols in telecommunications. The design consideration for the infrastructure for a Regional Electronic Navigational Chart Coordinating Centre (RECC) is dealt with in Chapter Five. Financial and institutional issues are discussed. Technical and non-technical security measure are commented upon. Chapter Six deals with the infrastructure design for a RECC. It examines the infrastructure components, system operation and maintenance and manpower. Strategies for implementing RECC in the sub-Saharan Africa are discussed in Chapter Seven. Network development, data and system security measures are commented upon. Chapter Eight looks at the legal implications of ECDIS and WEND. It examines the elements of the legal regime and speculates on the possible changes that could be brought about as a result of the changing technology. Chapter Nine concludes the report with recommendations on a regional WEND centre.

Abstract:

The use of co-ordinates as a description of land boundaries and their limitations has been investigated given recent advances in GPS measurement technology and its proliferation in the surveying and mapping industry. While the use of coordinate information is in essence a representation of reality at a given point in time, it is shown that they can be used within a well-defined framework for summary purposes. The conceptual and operational elements of a measurement-based spatial information system are developed in order to determine if it could aid in the organisation of land boundary information. The fundamental concepts of this information system are that measurements are the primary carriers of metric information. The investigation reveals that measurement-based concepts can serve as the foundation of a multi-purpose spatial information system. Increasing instrument precisions available to surveyors are providing quality measurements with decreasing uncertainties from standard daily operations. Much of this measurement information is in digital form and can provide useful additions of new information as and when they become available to the system. Control measurements are integrated into the system in the same manner as cadastral measurements. The addition of measurements increases the accuracy of the information system over time.

The knowledge of the distribution of the soils allows the planning of agricultural activities in a way to maximize the productivity of cultures and reduce the environmental degradation. That way, the water and nutrient availability to the plants become of great importance and may be evaluated by means of physical, chemical and mineralogical analysis and its interpretation of local conditions. This study had the objective of surveying and mapping the soils of a hydrographic microbasin used in the culture of eucalyptus, relating its physico-hydrical and chemical characteristics with the culture development. The study area has 63,53 hectares and belongs to VPC Florestal, located in the Alamos Farm in the city of Pinheiro Machado, where the culture of eucalyptus saligna is being cultivated. To represent the mapping units were characterized in field and collected 9 soil profiles, representing the classes of Argisoils, Cambisoils, Chernosoils, Luvisoils and Neosoils. In relation to total nutrients, the class of soil that presented the greater quantity of available nutrients in t.ha-1 in the microbasin was the Cambisoil, followed by Luvisoil, Chernosoil, Neosoil and Argisoil. Relating to total nutrients, the class of soil that showed a greater quantity in t in the microbasin was the Argisoil, followed by the Neosoil, Luvisoil, Chernosoil and Cambisoil. The soils present in the hydrographic microbasin of the Alamos Farm have a total of 1300 basic available cations and a total of 15770 basic cations. As for the water availability, the Alamos Farm has a storing capacity in its soil of 121245m³ of water, of those 20778m³ available to the plants. Relating to the development of eucalyptus, the results show there was a differentiated growth in different soil mapping units, and the greater growth was showed in the class of Argisoil.

Dessa forma, a reserva e a disponibilidade de água e de nutrientes para as plantas se tornam de grande importância, podendo ser avaliadas por meio de análises físicas, químicas e mineralógicas dos solos e da sua interpretação para as condições locais. Este estudo teve por objetivo, fazer um levantamento e mapeamento dos solos em uma microbacia hidrográfica utilizada com a cultura do eucalipto, relacionando suas características físico-hídricas e químicas com o desenvolvimento da cultura. A área de estudo, com 63,53 hectares, está localizada na Fazenda Álamos, pertencente a VCP Florestal, no município de Pinheiro Machado, onde está sendo cultivada a cultura do eucalipto saligna. Para representação das unidades de mapeamento foram caracterizados a campo e coletados 9 perfis de solo, representando as classes dos Argissolos, Cambissolos, Chernossolos, Luvissolos e Neossolos. Em relação aos nutrientes, a classe de solo que apresentou uma maior quantidade de nutrientes disponíveis em t.ha-1, na microbacia, foi o Cambissolo, seguido do Luvissolo, do Chernossolo, do Neossolo e dos Argissolos. Em relação aos nutrientes totais, a classe de solo que apresentou uma maior quantidade em t.ha-1, na microbacia, foi o Argissolo, seguido do Neossolo, do Luvissolo, do Chernossolo e do Cambissolo. Os solos presentes na microbacia hidrográfica da Fazenda Álamos, possuem um total de 1300t.ha-1 de cátions básicos disponíveis e um total de 15770t.ha-1 de cátions básicos totais. Quanto à disponibilidade de água, a microbacia da Fazenda Álamos, possui uma capacidade de armazenamento de água em seus solos de 121245m3 de água, destes 20778m3 disponíveis as plantas. Em relação ao desenvolvimento do eucalipto, os resultados mostram que houve um crescimento diferenciado, conforme a unidade de mapeamento de solos, sendo observado o maior crescimento na classe dos Argissolos.

Abstract:

Although the physical characteristics of surfing breaks are well described in the literature, there is little specific research on surfing and coastal management. Such research is required because coastal engineering has had significant impacts to surfing breaks, both positive and negative. Strategic planning and environmental impact assessment methods, a central tenet of integrated coastal zone management (ICZM), are recommended by this thesis to maximise surfing amenities. The research reported here identifies key oceanographic considerations required for ICZM around surfing breaks including: surfing wave parameters; surfing break components; relationship between surfer skill, surfing manoeuvre type and wave parameters; wind effects on waves; currents; geomorphic surfing break categorisation; beach-state and morphology; and offshore wave transformations. Key coastal activities that can have impacts to surfing breaks are identified. Environmental data types to consider during coastal studies around surfing breaks are presented and geographic information systems (GIS) are used to manage and interpret such information. To monitor surfing breaks, a shallow water multibeam echo sounding system was utilised and a RTK GPS water level correction and hydrographic GIS methodology developed. Including surfing in coastal management requires coastal engineering solutions that incorporate surfing. As an example, the efficacy of the artificial surfing reef (ASR) at Mount Maunganui, New Zealand, was evaluated. GIS, multibeam echo soundings, oceanographic measurements, photography, and wave modelling were all applied to monitor sea floor morphology around the reef. Results showed that the beach-state has more cellular circulation since the reef was installed, and a groin effect on the offshore bar was caused by the structure within the monitoring period, trapping sediment updrift and eroding sediment downdrift. No identifiable shoreline salient was observed. Landward of the reef, a scour hole ~3 times the surface area of the reef has formed. The current literature on ASRs has primarily focused on reef shape and its role in creating surfing waves. However, this study suggests that impacts to the offshore bar, beach-state, scour hole and surf zone hydrodynamics should all be included in future surfing reef designs. More real world reef studies, including ongoing monitoring of existing surfing reefs are required to validate theoretical concepts in the published literature.

Abstract:

This chapter examines the place of charts and hydrographic surveying in the consolidation of a formal American empire after 1898 and the central place of environmental knowledge in the broader strategic debates concerning American empire in the post war period, 1899-1903. It follows the work of surveying vessels off Cuba and the Philippines, the emerging role of the Hydrographic Office and its leaders, and the strategic debates among officer-students at the United States Naval War College and the Navy’s top leadership in the General Board of the Navy in recognizing and debating the importance of the marine environment generally and the specific strategic features of various harbors and coastlines from the Caribbean to the Western Pacific. The chapter argues that charts, hydrographic surveying, and a larger cartographic discourse were central to the geography of American empire, particularly in projecting American sea power into the Western Pacific and the Caribbean.

Abstract:

The main field of application of a multi-beam echosounder is hydrographic surveying, in other words acquisition of bottom topography information. This kind of bathymetric data is needed by a large number of users for harbour and coastal zone management, resource exploration, hydrographic charting for safety of navigation and many other tasks. Tools for highly efficient investigation of the seafloor, including rapid sediment classification, as well as reliable object detection are of high interest to offshore construction projects. Throughout the last couple of years, ATLAS Hydrographic has been concentrating on the development of the next generation of hydrographic survey echosounders. One of the results is the ATLAS FANSWEEP 30 family of multi-beam echosounders (MBES). This family of sonars offers an innovative new approach of multi-beam echosounder technology for hydrographic surveys. The ATLAS FANSWEEP 30 COASTAL, the first member of the ATLAS FANSWEEP 30 MBES family, is breaking new ground. Innovations, such as Simultaneous Multi-Ping, wide bandwidth transducer, multiple time and multi-view scanning of the seafloor for object search, address a single purpose: to improve survey efficiency while multiplying data reliability and resolution. With the FS30C the new Simultaneous Multi-Ping (SMP) is introduced. SMP utilises the complete frequency range between 100 kHz and 200 kHz to transmit and receive eight frequency separate pings at every ping interval. Four of these eight pings are forward, the other four backward looking mapping the seafloor from two independent directions. Thus, every bit of the mapped seafloor is looked at from two different directions. The 8x Simultaneous Multi-Ping enables the hydrographer to run the survey operation at high speeds. Still, the 8x SMP can ensure more than 300% bottom ensonification. That means every patch of seafloor is measured at least 3-times at one pass. The gained data redundancy is used to enhance not only data accuracy and reliability, but in particular the capability to recognise objects on the sea floor. Beginning at signal transmission, through reception beamforming to the point of real-time data gridding capabilities, the complete data flow is controlled by a built-in data evaluation solution. The new ATLAS FANSWEEP 30 COASTAL is a well suited tool to satisfy actual and upcoming demands in highly efficient and most reliable survey operations.

Abstract:

The paper presents analysis of determination of vertical movement of the surveying boat called “heave” with the use of Robotized Total Station (RTS) technique. The classical geodetic Total Station was used for sub-centimeter calculation of water level changes during hydroacoustic measurements on the fragment of Vistula river behind the dam and hydropower in Włocławek in Poland. The power station work causes up to 1.7 m movement of vertical reference water surface in aspect of local bathymetric survey. The experimental, hydrographic surveys on the river were conducted where the water level was changing significantly over time depending on the operational schedule of the power plant. Verified hydrographic data had to be brought to the common water level. To determine the final water level, data on the height of the Robotized Total Station prism positioned on the boat during sounding was considered. The RTS technique with 0.02–0.05 m vertical accuracy proved to be very useful and essential in engineering inland bathymetric measurements.

Abstract:

Abstract ADNOC is in the process of connecting Abu Dhabi's offshore sites to onshore electricity grid by the year 2025, through subsea transmission network that is expected to reduce costs and replace gas used for power generation. As part of the project tender, ADNOC was required to submit Geophysical Seabed Survey for two cable routes from Abu Dhabi mainland to target offshore sites (approx. 180km). ADNOC Offshore survey team were assigned with the task. Capitalizing on its technical industrial partners, ADNOC Offshore took the initiative to deploy several surveying technologies with one being deployed for the first time. An Unmanned Survey Vessel (USV) was deployed for one of the challenging nearshore segments of the route (for 24km) for the very first time in UAE waters for engineering design requirements. The unmanned hydrographic survey vessel was remotely controlled using telemetry solution including Domo Tactical Communications (DTC) radio and 4G communication system to overcome several onsite data acquisition challenges, which enabled project delivery for fraction of a cost while complying with high quality standards including operational flexibility for very shallow areas and absolutely no exposure of personnel. The company not only managed to deliver the entire geophysical data requirement on time, but also introduced a new technology that will open a new world of potential applications in the marine operations like surveillance, patrolling, geophysical surveys, light cargo shipping over short distance, etc. This will bring sustainable efficiency and effectiveness to marine operations and substantially save operational costs on large-scale implementation.

Abstract:

With the advancement of differential, kinematic GPS techniques, water level measurements with the accuracy of centimeter- or decimeter-level is possible when buoys are placed close to a coastal base station or at distances of thousands of kilometers from shore, respectively. Applications of these techniques to observe tides and waves and to detect tsunamis have been demonstrated. This paper will first briefly review existing water level measurement methods, the needs for coastal and open ocean water level measurements, previous GPS buoy experiments, and GPS measurement uncertainties and precision positioning techniques. These will then be followed by a brief description of the application of GPS buoys in hydrographic surveying and the development of a real-time water level reporting GPS buoy to support US National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS) nautical charting mission. The present measurement system consists of a portable spherical buoy and a shore base station. Utilizing Real-Time Kinematic (RTK) differential GPS technique, accurate water level data were collected and reported in real-time at six- minute intervals in complying with NOS water level measurement standards. The buoy’s motion sensors provide automated corrections for wave-induced buoy motions. Several field tests conducted near NOAA water level stations have shown that the root-mean-square (rms) of differences between the two measurement systems is on the order of 2 cm. The buoy also provides surface wave information. The portability and the accuracy of the system offer possibilities for other applications in coastal waters. Future enhancements include satellite data telemetry and monitoring, option for post processing, and solar power supplementation.
