Radium 228 and Radium 226 in surface water of the Kara Sea and Laptev Sea
The surface water in the Transpolar Drift in the Arctic Ocean has a strong signature of 228Ra. In an earlier study of 228Ra in the open Arctic we showed that the major 228Ra... -

The scavenging of 231Pa and 230Th was investigated in the Atlantic Sector of the Southern Ocean by combining results from sediment trap and in situ filtration studies. We... -
Compilation of 231Protactinium/230 Thorium excess ratios in various surface s...
In large areas of the world's oceans, there is a relationship between the mass flux of particulate matter and the unsupported 231Pa/230Th (xs231Pa/xs230Th) activity ratio of... -

Lead and aluminum in Atlantic surface water measured along the track of POLAR...
Lead and aluminum were measured with a 40–100 km resolution in surface water on two transects across the Atlantic Ocean, one in May 1990 from Cape Town to the North Sea, the... -
Thorium isotopes in the water column in Amundsen Basin during POLARSTERN crui...
In this study we present dissolved ²³⁰Th and ²³²Th results, as well as amount of particulate ²³⁴Th from total ²³⁴Th. The data, obtained as part of the GEOTRACES central Arctic... -
Pore-water manganese, nitrate and oxygen data and solid-phase radionuclide an...
The manganese nodule belt within the Clarion and Clipperton Fracture Zones (CCZ) in the abyssal NE Pacific Ocean is characterized by numerous seamounts, low organic matter (OM)... -

In this study we present dissolved and particulate 230Th and 232Th results, as well as particulate 234Th data, obtained as part of the GEOTRACES central Arctic Ocean sections... -
231Pa/230Th measurements and related isotope series and SiO2 of five sediment...
Downcore measurements of SiO2 and 231Pa/230Th on sediment cores from the New Zaland Margin and the East Pacific Rise. The sediment cores were collected during expedtions PS75... -
Terrigenous input and marine productivity for the Pacific sector of the South...
In this study, we present a new multiproxy data set of terrigenous input, marine productivity and sea surface temperature (SST) from 52 surface sediment samples collected along... -
Quantification and molecular characterization of dissolved organic sulfur in ...
Although sulfur is an essential element for marine primary production and critical for climate processes, little is known about the oceanic pool of non-volatile dissolved... -
Net community production, Thorium-234 activity and particle flux during the S...
A closed eddy core in the Subantarctic Atlantic Ocean was fertilized twice with two tons of iron (as FeSO4), and the 300 km2 fertilized patch was studied for 39 days to test... -
Radium in Arctic surface water
The transpolar drift is strongly enriched in 228Ra accumulated on the wide Arctic shelves with subsequent rapid offshore transport. We present new data of Polarstern expeditions... -
230Th, 231Pa, and 10Be in particle size fractions of an opal-rich sediment of...
This study centers on the question: How sensitive are 231Pa/230Th and 10Be/230Th to sediment composition and redistribution? The natural radionuclides 231Pa, 230Th and 10Be... -
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...
