Titan: A new facility for ultraclean sampling of trace elements and isotopes in the deep oceans in the international Geotraces program
International audience Towards more rapid ultraclean sampling of deep ocean waters for trace elements, a novel rectangular frame was constructed of titanium, holding two rows of 12 samplers, as well as various sensors. The frame is deployed to deep ocean waters by an 8000 m length Kevlar wire with i...
