The NAT GT10 2010 cruise\u2019s aim was to obtain state of the art trace metal and isotope measurements on a collection of samples taken on the mid-latitude zonal transect of the North Atlantic. This cruise was dived into two separate legs: KN199-04 and KN199-05.<\/p>\n\n\n\n

The first leg, KN199-04, targeted the oxygen minimum zone off the west African coast and the TAG hydrothermal field.<\/p>\n\n\n\n

Science Objectives: To obtain state of the art trace metal and isotope measurements on a suite of samples taken on a mid-latitude zonal transect of the North Atlantic. In particular, sampling targeted the oxygen minimum zone extending off the west African coast near Mauritania, the TAG hydrothermal field, and the western boundary current system along Line W. For additional information, please refer to the GEOTRACES program Web site (https:\/\/www.geotraces.org\/<\/a>) for overall program objectives and a summary of properties measured.<\/p>\n\n\n\n

Science Activities include seawater sampling via GoFLO and Niskin carousels, in situ pumping (and filtration), CTDO2 and transmissometer sensors, underway pumped sampling of surface waters, and collection of aerosols and rain. Hydrography, CTD and nutrient measurements were supported by the Ocean Data Facility (J. Swift) at Scripps Institution of Oceanography and funded through NSF Facilities. They provided an additional CTD rosette system along with nephelometer and LADCP. A trace metal clean Go-Flo Rosette and winch were provided by the group at Old Dominion University (G. Cutter) along with a towed underway pumping system.<\/p>\n\n\n\n
