Data Description This cruise report provides a record of data collected aboard the SSV Corwith Cramer during

cruise C-226 (U.S. State Department Cruise 2009-083), which departed from Christiansted, St.

Croix on 29 November 2009 and transited through the Caribbean Sea, arriving in Key West,

Florida on 21 December 2009 (Figure 1). This cruise was part of a joint program offered by

the Sea Education Association (SEA) and the Boston University Marine Program (BUMP).

Figure 1: C-226 cruise track plotted from hourly positions.

During the voyage we collected samples or data at 31 discrete oceanographic stations (Table

1), at which we performed 84 separate scientific deployments (Table 2). We also continuously

sampled water depth and sub-bottom profiles (CHIRP system), upper ocean currents (Acoustic

Doppler Current Profiler, ADCP), and sea surface temperature, salinity, in vivo fluorescence,

CDOM fluorescence and transmittance (via a seawater flow-through system). This report

summarizes sea surface biological and chemical characteristics (Tables 3 and 4), biological

and chemical properties with depth (Tables 5 and 6), and surface sediment characteristics

(Table 7). Lengthy CTD, CHIRP, ADCP, and flow-through data are not reported here. All

unpublished data may be made available by arrangement with the Sea Education Association

(SEA) data 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 and Boston University.

As part of the SEA-BUMP educational program, students conduct oceanographic research at

sea for studies they have designed prior to the cruise. Student projects span the four major

disciplines of oceanography – physical, chemical, biological, and geological oceanography

(Table 8). Student research efforts culminate in a written research paper and an oral

presentation to the ship’s company. The student research papers from cruise C-226 are

available upon request from SEA or Boston University.
