Antarctic subglacial carbonates as archives of subglacial volcanism and Life in extreme conditions - SamplesThis dataset lists samples of carbonate crusts formed under the ice of the East Antarctic Ice Sheet. These crusts mostly consist of Calcium Carbonate (CaCO3), and have ages spanning from older than 400,000 years to circa 17,000 years. The dataset "samples" provides the name for each specimen, where it was collected (Geographic Coordinates), its mineralogical composition and where the samples are a

TEM images and spectroscopy of insoluble particles in an ice core from Law Dome, East AntarcticaThis archive includes TEM images and spectroscopy of particles from an ice core from Law Dome, East Antarctica (DSS 05/06). The images are organized into three folders labelled 1795, 1838, and 1930 Common Era (C.E.). These dates correspond with the mean age of the meter of ice core melted for sampling. The depth/age scale of the ice core was constructed by matching dissolved ion chemistry and wate

Identity, composition and abundance of protists - data collected from the BROKE-West voyage of the Aurora Australis, 2006The BROKE-West survey was conducted from 30 degrees E and 80 degrees E between January and March 2006. It consisted of 1 east-west transect at the northernmost limit of the survey between 60 degrees S and 62 degrees S between the 10 and 19 of January, followed by 11 meridional transects separated by 5 degrees of longitude and extending from approximately 62 degrees S to the Antarctic continental s

Large Viruses in Ross Sea Pack IceThis data set contains the abundance of large (> 110 nm casid diameter) viruses from ice cores, brine, slush and water directly below the ice. This size class of viruses is likely to have infected eukaryotes. Samples were collected on two cruises to the Ross Sea. The first cruise was from 9 May 1998 to 11 June 1998, with sampling at approximately every degree of latitude from 66 to 78 degrees sout

Petrological distinctive features of the Neagari meteoriteIn the midnight on 18th of February 1995, a meteorite has fallen down in a corner of shopping street in the central part of the Neagari-Cho near the Terai Station on the Hokuriku Main Line of JR. The total weight of this meteorite was about 420 g. A measurement of petrological distinctive features of this meteorite and the cosmic ray originated radioactive nuclides has been carried out.

Effect on Narcissus Plant by Exhaust Emissions Derived from Diesel EnginePolluted narcissuses by exhaust emissions derived from a diesel engine twice a day were investigated by scanning electron microscope-energy dispersive X-ray analyzer, transmission electron microscopy and X-ray fluorescence spectrometer analyses. Polluted narcissuses were characterized by no flower, deformed leave and the change of color from green to yellow and black. S was increased about 6 times

A biological reconnaissance of the photoreceptors of invertebrates and fish from the Ross Sea, identifying the micro fauna and flora of Dry Valley lakes and other organism from the Ross Sea regionA variety of research activities on the organisms in the Ross Dependency was undertaken to determine the biological research potential of the organisms. Most work focused on photoreceptors of different invertebrates and fishes. The studies included work on: a) Glyptonotus antarcticus: The dorsal and ventral eyes of this big isopod were prefixed, postfixed, dehydrated and embedded for transmission

Mineralogical and Chemical Characteristics of Biomats in the Mining and Mineral Deposit AreaFormation of various biomats is commonly observed in the waste rocks and drainage ditches in the surrounding area of mines and deposits. By the electron microscopic observation of the biomats, the deposition of heavy metals and the formation of minerals in the cell of microorganisms and algae are observed. This paper presents the results observed in the drainage ditches of Omori Silver Mine and Ho

Anatomical and physiological adaptations in Antarctic fishesDermal and epidermal chromatophore tissue of two species of fishes (Pagothenia borchgrevinki and Trematomus bernacchii) were prepared for light and transmission electron microscopy. Some specimens of P. borchgrevinki melanophores were treated with tannic acid and prepared for immunofluorescence microscopy in order to study microtubule organization. The effects of dark/light, ionic solutions and dr

Characteristics of Acid Precipitation in Kanazawa CityThe concentration of nitrogen dioxide in atmosphere at 200-300 sites in Kanazawa City was measured. At the same time the rain, snow, hail and dust in atmosphere were sampled and concurrently were observed and analyzed by using an X-ray powder diffractometer, scanning electron microscope-energy dispersion diffractometer, and transmission type electron microscope. In general, the concentration of ni

Pentasil zeolites from Mt Adamson (Northern Victoria Land): a key for the synthesis of new materials for eterogeneous catalysis and for the confinement of nano-materials.Zeolites are a group of minerals and synthetic materials that have increased enormously in industrial and economic importance in recent decades. In addition to traditional applications in the purification of waste water and as additives in detergents (as molecular sieves and ion exchangers), valuable new economic applications have emerged. These include use in heterogeneous catalysis (for example,

Electron Microscopic Observation of Biomineralization in Biomats from Hot SpringsSince June 29 through July 5, 1992, an exploration of geysers in Iceland has been conducted. Temperature and pH of the geyser were 12-90 degrees C, and 6-9 respectively. In addition, the biomats were sampled from 7 sites of 6 regions, and their microform, mineral composition, and chemical constituents were examined.
