Cruise Report S-200 : Scientific data collected aboard SSV Robert C. Seamans Honolulu, Hawaii – San Francisco, California. 5 July – 2 August 2005
MetadataShow full item record
This cruise report provides a record of data collected during S-200 aboard the SSV Robert C. Seamans on her voyage from Honolulu, Hawaii to San Francisco, California (Figure 1). We collected samples or data at 69 discrete oceanographic stations (Table 1) Continuous measurements included sea surface temperature, salinity, and in vivo fluorescence from the ship’s flow through system, and subsurface currents with a hull-mounted Acoustic Doppler Current Profiler (ADCP). This report summarizes sea surface chemical and biological characteristics (Tables 2-4), subsurface biological samples (Table 4), chemical properties with depth (Table 5), and sediment grain size (Table 6). Largescale hydrography of the NE Pacific shows low salinity intermediate water masses and both thermocline and deep chlorophyll maximum shoaling eastward (Figure 2). ADCP data reveal locations and sizes of mesoscale eddies in the NE Pacific, and the strength and depth of zooplankton vertical migration (Figure 3). Lengthy CTD, ADCP, and flowthrough data are not reported here. All unpublished data can be made available by arrangement with the Sea Education Association (SEA) archivist (contact information, p.2). The information in this report is not intended to represent final interpretation of the data and should not be excerpted or cited without written permission from SEA.
