Biogeochemical Cycling of Iron and Phosphate under low Oxygen Conditions


This subproject combined water column and porewater sampling in the Oxygen Minimum Zone (OMZ) of the Tropical Eastern Pacific (Peru Upwelling) and Tropical Eastern Atlantic (Guinea Dome). The stated goal was to improve our understanding of benthic-pelagic coupling in the ocean at present by examining key chemical species, whose chemical behaviour and distribution are altered via oxygen mediated redox changes, most notably the key nutrients iron and phosphate, in both the water column and sediment porewaters simultaneously.
