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. 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. Unpublished data can be made available by

As part of SEA’s educational program, undergraduates conducted student-designed oceanographic
research during the cruise. 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. These papers are available on request from SEA.
