We conducted a sequential chemical extraction experiment for radiocesium (134Cs + 137Cs) using 21 surface sediment
samples and two sets of size-fractionated surface sediment samples collected offshor...
Factors controlling the geochemical composition of Limnopolar Lake sediments (Byers Peninsula, Livingston Island, South Shetland Island, Antarctica) during the last ca. 1600 years

The main input of phosphorus to the ocean is associated with river runoff, while this element leaves the marine system
via burial in the sediments. Solid phase P accumulation is a function of bottom ...
