Introduction

This cruise report provides a summary of scientific activities aboard the SSV Corwith Cramer

during cruise C-235 (14 May – 16 June 2011). The 2486 nm cruise served as the second half of

the 12-week Sea Semester: Energy and the Ocean Environment program with Sea Education

Association (SEA), during which extensive oceanographic sampling was conducted for both

student research projects (Table 1) and the ongoing SEA research program. Students examined

physical, chemical, biological, and environmental oceanographic characteristics in accordance

with their written proposals and presented their results in a final poster session and papers

(available upon request from SEA).

The brief summary of data contained in this report is not intended to represent final data

interpretation and should not be excerpted or cited without written permission from SEA.

Data Description

This section provides a record of data collected aboard the SSV Corwith Cramer cruise C-235 (US

State Department Cruise: 2010-108) from Key West, Florida, USA to Woods Hole, Massachusetts,

USA (Figure 1). Port stops were made at Grand Isle, Louisiana and Key West, Florida on the way to

Woods Hole, Massachusetts.

Figure 1. Hourly positions along the C-235 cruise track.

During the five-week voyage, we sampled at 84 discrete oceanographic stations (Table 3). In

total 46 surface samples were taken coincident with hydrocast and neuston tow stations (Table

4). Additionally, we continuously sampled water depth and sub-bottom profiles (CHIRP system),

upper ocean currents (ADCP, Figure 2), and sea surface temperature, salinity, and in vivo

fluorescence, CDOM, and transmittance (seawater flow-through system, Figure 3 – temperature,

salinity and fluorescence).

Vertical temperature and salinity profiles were taken with the CTD (Figure 4). Additional

instrumentation on the CTDs allowed for profiling of dissolved oxygen, fluorescence,

transmittance, PAR and CDOM (Figure 5). Summaries of sea surface and water column

chemical and biological properties are found in Tables 4-7. Lengthy CTD, CHIRP, ADCP, and

flow-through data are not fully presented here. All unpublished data can be made available by

arrangement with the SEA data archivist (contact information, p. 2).
