Summary of Field Work: |
This work will consist of a single 6-day cruise in which we occupy one high resolution section across the Gulf Stream, sampling the upper water column for nutrients and water samples for nitrogen fixation incubations and molecular analyses. Approximate details are:
• Depart: GSO pier 4/29/2017 with science party of approximately 8 from this project and 6 from Rainer Lohman’s cruise. All equipment from both projects loaded at GSO pier, including 12-bottle Rosette with 12 or 20 L Niskin Bottles, CTD and O2 sensor, incubators, and nutrient bottles.
• Steam to Gulf Stream, heading approx. due south
• Start occupying section at approx. 37.25°N, 72°W; occupy approx. 12 stations at 15 km separation to approx. 35.5°N, 72°W. Exact locations to be determined from instantaneous position of the Gulf Stream.
• At each station: wire out on Rosette to 1000 m. Twelve bottles for nutrients and salts, with an emphasis on the upper 500 m.
• Depths for incubations and molecular analysis: 2 euphotic zone, 2 mesopelagic at every other station (6 total)
• Steam to Morehead City, NC. Palter and her students disembark; Rainer Lohman and the remainder of his crew join.
• Lohman’s cruise plan commences with Granger and Moisander (and students) continuing their incubations and possibly collecting more samples in the Carribean.
• Remaining science party unloads in Everglades. |
