Cruise Report C-200 : Scientific data collected aboard SSV Corwith Cramer, Woods Hole, MA – Sable Island, Canada – Halifax, Nova Scotia – Woods Hole, MA, 6 July, 2005 – 2 August, 2005

Abstract

This cruise report provides a record of data collected during C200 aboard the SSV Corwith Cramer from Woods Hole, MA, USA to Sable Island, Canada, continuing on to Halifax, Nova Scotia, Canada and returning to Woods Hole (Figure 1). We collected samples or data with 98 individual deployments from 37 discrete stations (Table 2) along our cruise track. In addition we continuously sampled water depth, sub-bottom profiles and Acoustic Doppler Current Profiles (ADCP) along with flow-through sea surface temperature, salinity and in vivo fluorescence. This report summarizes physical, chemical and biological characteristics at the sea surface (Table 3, Figure 2) and at depth (Tables 4 and 5, Figure 3a) along our cruise track. A complete oceanographic survey of two submarine canyons (Hydrographer’s canyon south of Georges bank and The Gully, east of Sable Island) were completed. Bathymetry and surface currents for each seamount are available on request. Temperature, salinity and fluorescence profiles are presented (Figures 3b and 3c). Large scale hydrography is summarized by contour plots of temperature, salinity and fluorescence (Figure 4); whereas large scale current patterns are summarized by contour plots of current direction, magnitude and echo amplitude (Figure 5). In addition, the distribution and density of zooplankton at the sea surface (Table 6) and at depth (Figures 7 and 8) are presented. Sediment samples were sieved and grain size percentage of each fraction was determined (Figure 9). Additional CTD, bathymetry (CHIRP), current (ADCP) and biological data are not reported here but are available on request through Sea Education Association (SEA) and the Chief Scientist.

Project topics included physical, chemical, biological and geological oceanography (Table 10). Student research efforts culminated in a written report and public presentation to the ship’s company.
