Objectives | US GEOTRACES East Pacific Zonal Transect (EPZT), a survey consisting of rosette/CTD casts, McLane in situ pump and 7Be pump casts and a variety of underway measurements. A sea-going science team gathered from 15 oceanographic institutions participated.
Two types of rosette/SBE9plus CTD casts (ODF/30L-Niskin and GT-C/12L-GoFlo) were made at 36 station locations. Deep ODF/30L-Niskin casts included a device suspended 20 meters below the rosette, designed to either take a core sample or pick up particulates from the sea floor. Shallow and deep McLane pump profiles were done at all Full stations, with an additional mid-water profile at Super Stations. An SBE19plus CTD was attached to the end of the McLane wire on all but seven deep pump casts, when it was attached to the ODF rosette instead. Water was pumped and filtered for Beryllium-7 analysis on some stations. Underway samples were also collected for multiple programs, and five ARGO floats were deployed during the eastern half of the cruise for the University of Washington. |
