Fig. 1: Sampling locations on South Georgia Island.
From: Glacially derived iron is more bioavailable to Antarctic phytoplankton than other sources

a At two sites, seawater was collected as indicated by the red circles: Low chlorophyll water (LCW) and high chlorophyll water (HCW). To assess the bioavailability of Fe from different sources, a natural Fe-limited phytoplankton community (Phyto, red rectangle) was collected. b The different Fe sources were sampled in King Haakon Bay (south-western side of South Georgia) and Cumberland Bay (north-eastern side) as indicated by the red rectangles. Bathymetry from ref. 104.
