Compound--Specific Hydrogen Isotopes of Lipid Biomarkers in Lake El’gygytgyn, Ne Russia
Arctic Deuterium Organic Geochemistry Paleoclimate Stable Isotopes
2014/10/22
Recent successful drilling operations at Lake El'gygytgyn, NE Russia have recovered sediment cores back to 3.6Ma, representing the longest time-continuous sediment record of past climate change in the...
The role of polysaccharides and diatom exudates in the redox cycling of Fe and the photoproduction of hydrogen peroxide in coastal seawaters
polysaccharides and diatom exudates the redox cycling of Fe the photoproduction of hydrogen peroxide coastal seawaters
2010/1/21
The effect of artificial acidic polysaccharides (PS) and exudates of Phaeodactylum tricornutum on the half-life of Fe(II) in seawater was investigated in laboratory experiments. Strong photochemical h...
Growth phase dependent hydrogen isotopic fractionation in alkenone-producing haptophytes
Growth phase dependent hydrogen isotopic fractionation alkenone-producing haptophytes
2010/1/20
Recent works have investigated use of the hydrogen isotopic composition of C37 alkenones (δDK37s, lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. We discuss h...
Anomalous Strong Reflections on High Resolution Seismic Data from the Turkish Shelf of the Eastern Black Sea:Possible Indicators of Shallow Hydrogen Sulphide-Rich Gas Hydrate Layers
Black Sea gas hydrate hydrogen sulphide high-resolution acoustic methods
2010/1/11
Some strong reflections about 3 to 5 m thick were observed at depths of 25-60 metres below the sea floor using deep-towed, 5 kHz subbottom profiler data in the Turkish shelf and upper slope of the Eas...
The effect of temperature,salinity and growth rate on the stable hydrogen isotopic composition of long chain alkenones produced by Emiliania huxleyi and Gephyrocapsa oceanica
temperature salinity growth rate stable hydrogen isotopic composition long chain alkenones
2010/1/13
Two haptophyte algae, Emiliania huxleyi and Gephyrocapsa oceanica, were cultured at different temperatures and salinities to investigate the impact of these factors on the hydrogen isotopic compositio...
