Radionuclides measured on water bottle samples
Actinium is one of the rarest naturally occurring elements on earth. We measured its longest-lived isotope 227Ac (half-life 21.77 yr) for the first time in the water column of... -
Radionuclides of surface sediments and water samples in the South Atlantic so...
The fractionation of 230Th and 231Pa was investigated throughout the Atlantic sector of the Southern Ocean. Published scavenging models generally assume that the 231Pa/230T... -
Photophysiolgical parameters of Phaeocystis antarctica after exposure to diff...
Chlorophyll a fluorescence measurements were performed using a Fast Repetition Rate fluorometer (FRRf) coupled to a FastAct Laboratory system (FastOcean PTX, both from Chelsea... -
Absolute electron transport rates with increasing irradiance of Phaeocystis a...
At the end of the experiment, electron transport rates irradiance curves were conducted applying 8 irradiances from 0 up to ~400 μmol photons m-2 s-1 for 5 min for each light... -
Concentrations of total dissolved iron and dissolved manganese measured for t...
Total dissolved Fe (dFe) and Mn (dMn) concentrations were determined in the culture medium (without cells). To this end, 100 mL of seawater were filtered through HCl-cleaned... -
Intracellular trace metals content of iron and manganese of Phaeocystis antar...
For determination of the cellular trace metal content, at the end of the experiment 400 mL of water were filtered onto 0.2 μm TMC-cleaned polycarbonate filters (EMD Millipore,... -
