PurposeResearch
ObjectivesThe goals of the program were primarily educational - 15 academic colleagues from 13 different universities and colleges joined the SSV Corwith Cramer to learn about SEA Semester programs and to learn ocean sampling techniques and collect data for analysis. The research undertaken on this cruise was a study of the Caribbean Sea and North Atlantic waters in the regions of the U.S. Virgin Islands, British Virgin Islands, and Puerto Rico. To complete this study, we occupied seven oceanographic stations consisting of:

1. Water depth profiles (to 600m) of temperature, salinity, fluorescence, and dissolved oxygen using a CTD at two of the seven stations, with accompanying Niskin bottle samples at set depths for extracted chlorophyll-a and phosphate analyses.
2. Secchi disk measurements at two of the seven stations.
3. Surface Neuston zooplankton tows at four of the seven stations to look at species composition and density.
4. Drifted phytoplankton net samples at two of the seven stations.
5. Surface water samples at all seven stations for temperature, salinity, chlorophyll and colored dissolved organic matter (CDOM) fluorescence, and transmissivity, as well as extracted chlorophyll-a and phosphate analyses.

In addition, we collected the following continuous data sets during our voyage while underway:
1. ADCP measurements of ocean currents
2. CHIRP bottom profiles
3. Surface temperature, salinity, fluorescence, CDOM, turbidity, wind speed and direction.
