PhD defence: Sources and biogeochemistry of bio-active trace metals in the Southern Ocean and coastal Antarctica: perspectives from their isotopes

to

Deep sea and sediments bring iron to Antarctic waters.

Iron that fertilizes the waters around Antarctica, mostly comes from the deep, upwelling waters and the sediments around the continent. That is shown by field research of NIOZ marine biogeochemist Hung-An Tian in the Amundsen Sea and the Weddell Sea. “Iron plays a pivotal role in the Antarctic ecosystem and potentially also in the climate”, Tian says. “But meanwhile, we still know very little about the exact bookkeeping of iron in the Southern Ocean.”
