Abstract:

AbstractCompositional data—that is data where concentrations are expressed as proportions of a whole, such as percentages or parts per million—have a number of peculiar mathematical properties which make standard statistical tests unworkable. In particular correlation analysis can produce geologically meaningless results. Aitchison (1986) proposed a log-ratio transformation of compositional data which allows inter-element relationships to be investigated. This method was applied to two sets of geochemical data—basalts from Kilauea Iki lava lake and grantic gneisses from the Limpopo Belt—and geologically 'sensible' results were obtained. Geochemists are encouraged to adopt the Aitchison method of data analysis in preference to the traditional but invalid approach which uses compositional data.

Abstract:

Two thermophilic, Gram-stain-positive, rod-shaped, non-spore-forming bacteria (strains KI3T and KI4T) were isolated from geothermally heated biofilms growing on a tumulus in the Kilauea Iki pit crater on the flank of Kilauea Volcano (Hawai‘i, USA). Strain KI3T grew over an examined temperature range of 50–70 °C (no growth at 80 °C) and a pH range of 6.0–9.0, with optimum growth at 70 °C and pH 7.0. Strain KI4T grew at temperatures of 55–70 °C and a pH range of 5.8–8.0, with optimum growth at 65 °C and pH 6.7–7.1. The DNA G+C contents of strains KI3T and KI4T were 66.0 and 60.7 mol%, respectively. The major fatty acid for both strains was 12-methyl C18 : 0. Polar lipids in strain KI3T were dominated by glycolipids and phosphatidylinositol, while phosphatidylinositol and phosphoglycolipids dominated in strain KI4T. Strain KI3T oxidized carbon monoxide [6.7±0.8 nmol CO h−1 (mg protein)−1], but strain KI4T did not. 16S rRNA gene sequence analyses determined that the strains belong to the class Thermomicrobia , and that strains KI3T and KI4T are related most closely to Thermomicrobium roseum DSM 5159T (96.5 and 91.1 % similarity, respectively). 16S rRNA gene sequence similarity between strain KI3T and strain KI4T was 91.4 %. Phenotypic features and phylogenetic analyses supported the affiliation of strain KI3T to the genus Thermomicrobium , while results of chemotaxonomic, physiological and biochemical assays differentiated strains KI3T and KI4T from Thermomicrobium roseum . Strain KI3T ( = DSM 27067T = ATCC BAA-2535T) is thus considered to be the type strain of a novel species, for which the name Thermomicrobium carboxidum sp. nov. is proposed. Additionally, the characterization and phylogenetic position of strain KI4T showed that it represents a novel species of a new genus, for which the name Thermorudis peleae gen. nov., sp. nov. is proposed. The type strain of Thermorudis peleae is KI4T ( = DSM 27169T = ATCC BAA-2536T).

Abstract:

Proximity to magma bodies is generally acknowledged as providing the energy source for hot hydrothermal reservoirs. Hence, it is appropriate to think of a “magma–hydrothermal system” as an entity, rather than as separate systems. Repeated coring of Kilauea Iki lava lake on Kilauea Volcano, Hawaii, has provided evidence of an impermeable, conductive layer, or magma–hydrothermal boundary (MHB), between a hydrothermal system and molten rock. Crystallization on the lower face of the MHB and cracking by cooling on the upper face drive the zone downward while maintaining constant thickness, a Stefan problem of moving thermal boundaries with a phase change. Use of the observed thermal gradient in MHB of 84 °C/m yields a heat flux of 130 W/m2. Equating this with the heat flux produced by crystallization and cooling of molten lava successfully predicts the growth rate of lava lake crust of 2 m/a, which is faster than simple conduction where crust thickens at t and heat flux declines with 1 / t . However, a lava lake is not a magma chamber. Compared to erupted and degassed lava, magma at depth contains a significant amount of dissolved water that influences the magma’s thermal, chemical, and mechanical behaviors. Also, a lava lake is rootless; it has no source of heat and mass, whereas there are probably few shallow, active magma bodies that are isolated from deeper sources. Drilling at Krafla Caldera, Iceland, showed the existence of a near-liquidus rhyolite magma body at 2.1 km depth capped by an MHB with a heat flux of ≥16 W/m2. This would predict a crystallization rate of 0.6 m/a, yet no evidence of crystallization and the development of a mush zone at the base of MHB is observed. Instead, the lower face of MHB is undergoing partial melting. The explanation would appear to lie in vigorous convection of the hot rhyolite magma, delivering both heat and H2O but not crystals to its ceiling. This challenges existing concepts of magma chambers and has important implications for use of magma as the ultimate geothermal power source. It also illuminates the possibility of directly monitoring magma beneath active volcanoes for eruption forecasting.

Abstract:

AbstractAfter nearly 35 years of stable activity, the Kilauea volcanic system in Hawaii went through sudden changes in May 2018 with the emergence of 20 volcanic fissures along the Lower Eastern Rift Zone (LERZ), destroying 700 homes in Leilani Estates and forcing more than 2,000 people to evacuate. Elevated volcanic emissions lasted for several months between May and September 2018, leading to low visibility and poor air quality in Hawaii and across the western Pacific. The NASA-funded VolKilau mission was rapidly mounted and conducted between 11 and 18 June 2018 to (i) profile volcanic emissions with SO2 and aerosol measurements, (ii) validate satellite observations, and (iii) increase readiness for the next large volcanic eruption. Through a series of balloon-borne measurements with tethered and free-released launches, we measured SO2 concentration, aerosol concentration, and optical properties 60–80 km downwind from the volcanic fissures using gas sensors, optical particle counters, backscatter sondes, and an aerosol impactor. While most of the measurements made during the Kilauea eruption were ground based, the VolKilau mission represented a unique opportunity to characterize plume properties, constrain emission profiles, study early chemistry involving the conversion of SO2 into sulfuric acid, and understand the influence of water clouds in the removal of SO2. This unprecedented combination of measurements has significantly improved our team’s ability to assess the atmospheric and human impacts of a major event such as this.

Abstract:

The geochemical processes of fractional crystallization of a magma, partial fusion of a rock and assimilation or hybridization of rock(s) and/or magma(s) are generally termed as petrological mixing process. In the present paper a unified attempt has been made to describe the three processes under the purview of regression model. As the data involved are essentially compositional in nature, their suitable log-ratio transforms have been utilized and the constrained least squares principle has been applied to reach a meaningful solution. A highly accommodative procedure is suggested so as to describe any specified d~gree of fractional crystallization of magma or of partial fusion of a rock. The paper concludes with applications of the proposed method on data available from i) Rajmahal Trap, Eastern India (fractional crystallization) ii) Bihar Mica Belt, Eastern India (partial fusion) and iii) Kilauea Volcano, Hawai (formation of hybrid magma).

Abstract:

SUMMARY Miller (1977) proposed reconstructing the Old Korean accusative marker as hel < *gel and compared it with the Old Turkic accusative = j/=g, the Mongolian accusative =[ii]g, and the Tungusic directive-locative =kilaa/=kilii. His proposal was criticized in Martin (1990). I will argue that although Miller's proposal is valid as far as Old Korean is concerned, his comparison with Old Turkic, Tungusic, and possibly with Mongolian cannot be maintained. I will demonstrate on the basis of the internal evidence that Old Korean =yïl < Proto-Korean *=biî, and is therefore related to the corresponding accusative markers in Japanese and Tungusic. RÉSUMÉ En proposant de reconstruire l'accusatif du vieux coréen comme hel < *gel Miller (1977) compara l'accusatif avec ceux du turc ancien =y/=g, du mongol =[ii]g, et avec le directif-locatif toungouze =kilaa/=kilii.. Sa proposition fut critiquée par Martin (1990). L'auteur de cet article discute ici que la reconstruction de l'accusatif coréen ancien de Miller, mais qu'il est nécessaire de rejeter sa comparaison avec les marques de cas du turc ancien, du toungouze et peutêtre aussi du mongol. A partir des resources internes de la langue, je démontre que =yïl du vieux coréen < *=bïl du proto-coréen, et qu'il est conséquemment apparenté aux marques de cas accusatif en japonais et en toungouze. ZUSAMMENFASSUNG Miller (1977) schlug hel < *gel als rekonstruierte altkoreanische Akku-sativmarkierung vor und verglich sie mit dem alttiirkischen Akkusativ = y/=g, dem mongolischen Akkusativ =[ii]g und dem tungusischen Direktiv-Lokativ =kilaa/=kilii. Sein Vorschlag wurde in Martin (1990) kritisiert. In diesem Aufsatz wird dargelegt, daB, wenngleich Millers Vorschlag fur das Altkoreanische zutrifft, sein Vergleich mit dem Alttiirkischen, dem Tungusischen und vielleicht mit dem Mongolischen hingegen abgelehnt werden muB. Aufgrund internen Beweismaterials wird hier der Nachweis gefuhrt, daB altkoreanisch = yïl aus protokoreanisch *=bïl hergeleitet werden kann und deshalb mit den entsprechenden Akkusativmarkierungen im Japanischen und Tungusischen verwandt ist.

Abstract:

Basaltic volcanoes erupt in several different regimes which have not been explained. At Kilauea (Hawaii), eruption can take the form of either fire fountaining, where gas-rich jets propel lava clots to great heights in the atmosphere, or quiet effusive outflow of vesicular lava. Another regime is commonly observed at Stromboli, where large gas slugs burst intermittently at the vent. In an attempt to provide a unifying framework for these regimes, we investigate phenomena induced by degassing in a reservoir which empties into a small conduit. Laboratory experiments are done in a cylindrical tank topped by a thin vertical tube. Working liquids are silicone oils and glycerol solutions to investigate a range of viscosity and surface tension. Gas bubbles are generated at the tank bottom with known bubble diameter and total gas flux. The bubbles rise through the tank and accumulate in a foam layer at the roof. Depending on the behaviour of this foam layer, three different regimes can be distinguished: (i) steady horizontal flow of the foam leading to bubbly flow in the conduit; (ii) alternating regimes of foam build-up and collapse leading to the eruption of a single, large gas pocket; (iii) flow of the foam partially coalesced into larger gas pockets leading to intermittent slug flow in the conduit. These regimes have natural counterparts in basaltic volcanoes.A simple theory is proposed to explain regimes (i) and (ii). The bubbles in contact with the roof deform under the action of buoyancy forces, developing flat contact areas whose size increases as a function of foam thickness. Maximum deformation corresponds to a critical thickness hc = 2σ/ερlgR, where σ is the coefficient of surface tension, ρl the liquid density, g the acceleration due to gravity, R the bubble radius and ε the gas volume fraction in the foam. The foam thickness is determined by a balance between the input of bubbles from below and the output into the conduit, and is proportional to (μlQ/ε2 ρlg)¼, where μl is the liquid viscosity and Q the gas flux. A necessary and sufficient condition for collapse is that it exceeds the critical value hc. In a liquid of given physical properties, this occurs when the gas flux exceeds a critical value which depends on viscosity, surface tension and bubble size. Experimental determinations of the critical gas flux and of the time between two events of foam collapse are in agreement with this simple theory.

Abstract:

The Hawaii observatory is located at 190 34â€™ latitude, 1550 30â€™ longitude and 4207 sq m area. The island of Hawaii is built from fine separate shield volcanoes that erupted somewhat sequentially one overlapping the other. Moderate to strong trade winds carry as and vog from Kilauea volcano around the southern tip of the island. Ninety-nine percent of the gas molecules emitted during a volcanic eruptions are water vapor (H2O), carbon dioxide (Co2), and sulfur dioxide (So2). The remaining one percent is comprised of small amounts of hydrogen sulfide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species. The most critical factors that determine how much vog impacts any area are wind direction and speed. Where and how bad the vog is ultimately depends on several additional factors including air temperature, humidity, and rainfall emitted from KÄ«lauea Volcano. The Co2 atmosphere concentration measured at Mauna Lao observatory (MLO). Hawaii have been used by advocates of anthropological global warming (AGW) as a bell weather of climate. Carbon dioxide concentrations in units of parts per million (PPM) have been measured daily and monthly have been averages reported since 1958. We have analyzed Co2 data from 1958 to 2014, So2 data from 1979 to 1997, CH4 data from 1992 to 2001, rainfall data from 1920 to 2012, temperature data from 1955 to 2015 and ozone data from 1958 to 2014. Here We have analyzed and interpret to draw the line graphs and bar graphs in the following parameters ozone, carbon dioxide, methane, temperature and rainfall. We find the following parameters i) Co2 gradually increased from 1958 to 2014 ii) CH4 gradually increased from 1992 to 2001 iii) The So2 gradually increased and decreased from 1979 to 1997 iv) Mauna loa Temperature increased from 1955 to 2015 and Opihihale Temperature increased from 1965 to 2010 v) Rainfall increased and decreased from 1920 to 2012 vi) Ozone increased and decreased from 1958 to 2014.
