Grain size effects on excess Thorium-230 of sediment cores from the Southern ...
Excess Thorium-230 (230Thxs) as a constant flux tracer is an essential tool for paleoceanographic studies, but its limitations for flux normalization are still a matter of... -
Radionuclides measured on 21 water bottle profiles during POLARSTERN cruise A...
Drake Passage is a major route for many water masses from the strong Antarctic Circumpolar Current. During the ANTXXIV-3 expedition (in 2008) the vertical distributions of... -
Radionuclide analyses, and sedimentation and accumulation rates of sediment c...
There is increasing evidence indicating that syndepositional redistribution of sediment on the seafloor by bottom currents is common and can significantly affect sediment mass... -
Radionuclides of bulk and terrigenous surface sediments in the Southern Ocean
Sr and Nd isotopic compositions of Late Quaternary surface sediment and sediment cores from the south Atlantic and southeast Pacific sectors of the Southern Ocean are used to... -
Radionuclides in sediment cores of the Atlantic sector of the Southern Ocean
We present time series of export productivity proxy data including 230Thex-normalized deposition rates (rain rates) of 10Be, dissolution-corrected biogenic Ba, and biogenic opal... -
Radionuclides of sediment cores and a sediment trap in the Weddell Sea
The scavenging of 230Th and 231Pa was investigated in the central Weddell Sea by combining results from a sediment trap and three sediment cores. Scavenging of both... -
Radionuclides in the Weddell Sea
228Ra and its granddaughter 228Th were measured on a N-S transect from 45's to the Antarctic continent across the Antarctic Circumpolar Current (ACC) and the Weddell Sea. The... -
Radionuclides in the water column at stations near the Antarctic Polar Front ...
Vertical profiles of dissolved and particulate 230Th and 231Pa were obtained across the Antarctic Circumpolar Current (ACC) in the southern Atlantic. North of the Polar Front,... -
Biogeochemistry of the Eastern Weddell Gyre
The Southern Ocean (SO) plays a key role in modulating atmospheric CO2 via physical and biological processes. However, over much of the SO, biological activity is iron-limited.... -
Geochemistry of continental slope and deep sea basin sediments off Uruguay
Pore water and solid phase from surface sediments of the continental slope off Uruguay and from the Argentine Basin (southwestern Atlantic) were investigated geochemically to... -
Radionuclides and sedimentation rates of sediment cores from the eastern Sout...
High-resolution records of the natural radionuclide 230Th were measured in sediments from the eastern Atlantic sector of the Antarctic circumpolar current to obtain a detailed... -
