International Polar Year

This international study investigates the abundance, biological evolution, and speciation of trace elements and isotopes in the Arctic and Southern Oceans. The research focuses on metals like Mn, Fe, Co, Ni, Cu, Zn, Ag, Cd, Hg, and Pb, and their impact on biogeochemical processes. The study aims to understand the essential and toxic roles of these elements in biological systems.

  6. Advantages Titan system • 3-4 fold more efficient station time than single GO-FLO on hydrowire • no carrying GO-FLO samplers • much faster turnaround sub-sampling • system on shipboard always in clean room • stations CTD data for physics • now building new prototype samplers • 18 Liter volume, • pharmaceutical industry quality plastics
