Chemical composition of basalts from coarse debris of the Kara Sea bottom sed...
Study of basaltic debris from the Kara Sea bottom has shown its similarity to traps of the Eastern Siberia in mineralogy, structures and chemical composition. In comparison with... -
Sea surface temperature reconstruction on three sediment profiles off Portugal
Sea Surface Temperature (SST), river discharge and biological productivity have been reconstructed from a multi-proxy study of a high-temporal-resolution sedimentary sequence... -
Major and rare earth element contents and their speciations in ferruginous no...
Contents of Fe, Mn, Al, P, and rare earth elements (REE) in ferruginous nodules and host sediments of the eastern Barents Sea were studied. A direct Fe-P correlation in reactive... -
Geochemical and biogeochemical parameters of bottom sediments from the area o...
Quantitative characteristics for rates of diagenetic processes in the upper (0-30 cm) layer of sedimentary deposits in the area of the Spitsbergen (Svalbard) Archipelago... -
Abundance of benthic Foraminifera in the Kara Sea
Taxonomic composition and structure of assemblages of the present-day benthic Foraminifera in the Kara Sea has been studied on the base of 37 samples of surface sediments. Three... -
Sedimentary lipids and palynomorphs of sediment core ABC26 from the Eastern M...
Selective degradation of organic matter in sediments is important for reconstructing past environments and understanding the carbon cycle. Here, we report on compositional... -
Radiolaria in the surface layer of bottom sediments from the northern sector ...
Quantitative data on radiolarian assemblages from the Benguela upwelling at 17-25°S were obtained from analysis of 18 bottom sediment samples. The maximum abundance of... -
Grain size composition of metalliferous sediments from the East Pacific Rise ...
It is shown that a laser granulometric analysis makes it possible to obtain adequate results with respect to grain size composition of metalliferous sediments in contrast to... -
Uranium and thorium isotopes and sedimentation rates in metalliferous sedimen...
Isotopic compositions of uranium (234U and 238U) and thorium (230Th and 232Th) were measured in metalliferous sediments from the western flank of the East Pacific Rise at... -
Ages and sedimentation rates of bottom sediments from the south arid zone of ...
Radiocarbon datings are used to calculate mean sedimentation rates of metalliferous sediments in the southern arid zone of the Pacific Ocean adjoining the axis of the East... -
Modes of sapropel formation in the eastern Mediterranean: some constraints ba...
Pyrite formation within and directly below sapropels in the eastern Mediterranean was governed by the relative rates of sulphide production and Fe liberation and supply to the... -
Clay mineraology and grain size composition of surface sediments from South P...
The reconstruction of low-latitude ocean-atmosphere interactions is one of the major issues of (paleo-)environmental studies. The trade winds, extending over 20° to 30° of... -
Calcite saturation and dissolution index of core-top sediment samples from th...
X-ray computed tomography (CT) provides an insight into the progression of dissolution in the tests of planktonic foraminifera. Four species of foraminifera (G. ruber [white],... -
Clay mineral analysis of sediments from the Amundsen Sea
The Amundsen Sea embayment is a probable site for the initiation of a future collapse of the West Antarctic Ice Sheet. This paper contributes to a better understanding of the... -
Sedimentary record of the western Amundsen Sea Embayment
The Amundsen Sea Embayment (ASE) drains approximately 35% of the West Antarctic Ice Sheet (WAIS) and is one of the most rapidly changing parts of the cryosphere. In order to... -
Sedimentological and geophysical investigation of sediment cores from the Amu...
Ice loss from the marine-based, potentially unstable West Antarctic Ice Sheet (WAIS) contributes to current sea-level rise and may raise sea level by up to 3.3 to 5 meters in... -
Abundance and community structures of heterotrophic and oligotrophic bacteria...
Colony counts on high and low-nutrient agar media incubated at 2 and 20 °C, Acridine Orange Direct Counts and biomasses are reported for sediments of the Sierra Leone Abyssal... -
Rare earth element contents in deposits and minerals of the ocean floor
Current understanding of rare earth element (REE) geochemistry in the ocean is given in the book. Chemical properties determining REE migration ability in natural processes,... -
Geochemistry of sediments of stage 5 of the Nordic seas
Stable isotope, foraminifera and ice rafted detritus (IRD) records covering the last interglacial (the Eemian) from 7 sediment cores in a transect from the Norwegian to the... -
Sea surface temperature reconstruction based on planktonic foraminifera of su...
Quantitative and qualitative analyses of planktonic foraminiferal assemblages from 134 core-top sediment samples collected along the western Iberian margin were used to assess...
