Stable carbon and oxygen isotope ratios of benthic and planktic foraminifera ...
Benthonic foraminifera in late Pleistocene deep-sea cores show significant variation in delta 13C with depth in sediment. This, and the report by Sommer et al., (in prep) of... -
Stable carbon and oxygen isotope ratios of planktonic foraminifera from the e...
Carbon isotopic records of nutrient-depleted surface water place constraints on the past fertility of the oceans and on past atmospheric pCO2 levels. The best records of... -
Quaternary calcareous nannofossils from Periantarctic basins
Currently, coccolithophores have a widespread oceanic distribution and are reported from most latitudes, but not those higher than 65°S. Fifteen piston cores were sampled with... -
Size-related stable isotope changes in Late Cretaceous and Recent planktic fo...
The paleoecology of Cretaceous planktic foraminifera during the Late Cenomanian to Coniacian period (~95-86 Ma) remains controversial since much of the tropical marine record is... -
Response of deep-sea benthic foraminifera to Late Quaternary climate changes,...
The Late Quaternary benthic foraminifera of four deep-sea cores off Western Australia (ODP 122-760A, ODP 122-762B, BMR96GC21 and RC9-150) have been examined for evidence of... -
Diatom constrains on the position of the Antarctic Polar Front in the middle ...
The relative percentages of diatom taxa in 5 deep-sea cores (DSDP 266, ODP 699A, ODP 747A. ODP 751A, and Eltanin Core 50-28) from the Southern Ocean are determined for an... -
Sedimentology and geochemistry of Oxygen Isotope Stage 3 and Holocene sedimen...
Seismic reflection studies in the maar lake Laguna Potrok Aike (51°58? S, 70°23? W) revealed an erosional unconformity associated with a sub-aquatic lake-level terrace at a... -
Sedimentology and geochemistry of late glacial and Holocene sediments from La...
A high-resolution multiproxy geochemical approach was applied to the sediments of Laguna Potrok Aike in an attempt to reconstruct moist and dry periods during the past 16 000... -
Quarternary tephra layers in sediment cores from the Bellingshausen Sea and S...
The Southern Ocean is a region of the world's ocean which is fundamental to the generation of cold deep ocean water which drives the global therrno-haline circulation. Previous... -
Sedimentology of cores from the continental rise west of the Antarctic Peninsula
The continental rise west of the Antarctic Peninsula includes a number of large sediment mounds interpreted as contourite drifts. Cores from six sediment drifts spanning some... -
Sedimentology of various cores from the West Antarctic continental margin
Three megascopic and disseminated tephra layers (which we refer to as layers A, B, and C) occur in late Quaternary glaciomarine sediments deposited on the West Antarctic... -
Composition of noble gases in sediments and metasediments
Solar-type helium (He) and neon (Ne) in the Earth's mantle were suggested to be the result of solarwind loaded extraterrestrial dust that accumulated in deep-sea sediments and... -
Relative abundance of dinoflagellate cysts in surface sediments and dinoflage...
In this study we investigate the potential of organic-walled dinoflagellate cysts (dinocysts) as tools for quantifying past sea-surface temperatures (SST) in the Southern Ocean.... -
Sediment facies of the Indian-Pakistan continental margin, Indian Ocean Exped...
The studies described here base mainly on sedimentary material collected during the "Indian Ocean Expedition" of the German research vessel "Meteor" in the region of the... -
Palynology of marine sediment cores from the West African coast
Seven sediment cores from the cruises of the "Meteor" and "Valdivia" were examined palynologically. The cores were retrieved from the lower continental slope in the area of... -
Benthic foraminifera of surface sediments from the continental slope off Sier...
On "Meteor" cruise 30 (1973) 22 piston-cores were collected off Sierra Leone from water-depths between about 5000 m (Sierra Leone Basin) and 500 m (upper continental slope) with... -
Determination of Uranium, Thorium, and Ionium in sediment cores of the Caribb...
A rapid procedure for Io (Th230) dating of sediments with accumulation rates in the range of several cm/1000 years is described. Studying of large sample populations with very... -
Documentation of sediment cores from the Great Meteor Seamount, North Atlantic
Sedimentological and biostratigraphic investigations of 15 cores (total length: 88 m) from the vicinity of Great Meteor seamount (about 30° N, 28° W) showed that the calcareous... -
Geochemistry of recent sediments of the East African continental margin, Arab...
Chemical analyses have been carried out on 40 samples from the sediment surface and 210 samples from cores that were taken from the edge of the African continental block at the... -
Description of recent sediments of the East African continental margin
Recent sediments off East Africa coast show 5 fades, parallel the coast: biogene carbonate sand, olivgrey mud, foraminiferal sand, globigerine ooze, and deep sea clay. These...
