Chlorophyll a-content of all (total), the small (0.2-2 μm) and the large (> 2 μm) cells determined from the community sampled at station West and East (PS97) before and after exposure to different Fe and Mn availabilities ...
Two Fe-Mn bottle amendment experiments with two natural phytoplankton communities were performed during Polarstern expedition PS97 in 2016 in the Drake Passage. At two locations, sea water was pumped (using trace metals clean techniques) from 25m depth and used to fill polycarbonate bottles after ha...
