The 2115 nm, five-week cruise served as the scientific data collection portion of the Sea Semester: Marine Biodiversity & Conservation program with Sea Education Association (SEA). Extensive oceanographic sampling was conducted for both student research projects (Table 1) and the ongoing SEA research program. Students measured biodiversity and 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.

Figure 1. Hourly positions along the C-247 cruise track. During the 5-week voyage, we sampled at 38 discrete oceanographic stations (Table 2), each with an associated surface sample for chlorophyll a and total inorganic phosphate (Table 3). Additionally, we continuously sampled water depth and sub- bottom profiles (CHIRP system), upper ocean currents (ADCP, Figure 2), and sea surface temperature, salinity, CDOM fluorescence, in-vivo chlorophyll fluorescence, and transmittance (seawater flow-through system, Figure 3 – temperature, salinity). Discrete CTD measurements of vertical temperature and salinity profiles are presented in Figure 4. Additional instrumentation on the CTDs allowed for profiling of dissolved oxygen, fluorescence, transmittance, PAR and CDOM fluorescence. Summaries of sea surface and water column chemical and biological properties are found in Tables 4 and 5. 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 All unpublished data can be made available by arrangement with the SEA data archivist (contact information, p. 2). 7 Table 2. Oceanographic sampling stations. X indicates type of station.
