Down-core measurements of 231Pa/230Th for sediment core SO213/2_76-2
The concentrations of sedimentary 231Pa, 238U, 230Th, and 232Th were jointly measured by isotope dilution in a co-operation between AWI and Heidelberg University with... -

The Th230/Pa231 activity ratio in 7 of 11 manganese nodules is less than 10.8, the theoretical production ratio of activities in the ocean. This finding indicates difierential... -
Growth rates and possible age of a North Pacific manganese nodule
The rate of accumulation of a ferromanganese coating on a fragment of pillow basalt was estimated using a variety of techniques. Unsupported 230 Th activity decrease in the... -

Increased export production (EP) in the Subantarctic Zone (SAZ) of the Southern Ocean due to iron fertilisation has been proposed as a key mechanism for explaining carbon... -
Radionuclides, Nd isotopes and biogenic Opal in Atlanic Ocean sediments
Reconstructing past modes of ocean circulation is an essential task in paleoclimatology and paleoceanography. To this end, we combine two sedimentary proxies, Nd isotopes... -
