Summary of Field Work: |
This request for ship time is to support three independent research grants awarded to principal investigators at the Univesity of Maine, City College of New York, and the NASA Langley Center. The desired ship for this project is the RV ENDEAVOR. The desired cruise period is for TWO WEEKS IN EARLY AUGUST (exact dates are flexible). Expenses for ship support WILL BE PAID FOR BY THE NASA OCEAN BIOLOGY AND BIOGEOCHEMISTRY PROGRAM, managed by Dr. Paula Bontempi (202-358-1508). M.J. Behrenfeld is a co-investigator in this reseach and is the current lead on organizing ship support. The project will involve in-water and flow-through optical and biological measurements, above water optical measurements from the ship, an airborne campaign synchronized with the ship schedule (involving lidar and polarimeter measurements), and satellite data.
The details of the cruise plan have not been finalized yet among the various participating organizations, but a preliminary plan has been established. We would like to begin the research cruise from the Endeavor's home port or thereabout, transect into the Gulf of Maine, followed by a transect to near Bermuda, and finishing near the mouth of the Chesapeake Bay (e.g., Norfolk). The daily measurement plan will include roughly 4 stations per day (three during daylight hours and one at night). Station work will include deployment of a CDT Rosette to approximately 150 m, with sample water collected at 4 depths during ascent. Following the CTD cast, we will deploy an opticial package from the ship, with the ship maintaining position such that the optical instruments are not shaded by the ship. Finally, a teathered polarimeter package will be deployed away from the ship (up to 100 feet) and polarization properties measured at one (or perhaps 2) depths. It is anticipated that the suite of deployments at each station will require approximately 2 to 2 1/2 hrs. During the night deployment, the polarimeter measurements will not be conducted (i.e., they require sunlight).
In addition to the overboard measurements, optical instruments will be plumbed into the ship's clean seawater supply to cotinuously measure absorption, scattering, backscattering, and attenuation properties. Descrete samples will also be collected for analysis of particulate organic carbon, chlorophyll, and phytoplankton carbon (measured with a sorting flow cytometer).
In coordination with the ship measurements, airborne polarimeter and lidar measurements will be conducted. This effort will be led by Drs. Chris Hoestetler (NASA Langley) and Brian Cairns (NASA GISS). The airborne measurements will survey waters transected by the ship, and coordination between platforms will be necessary to ensure overflights of the ship during the 3 daytime deployments. |
|
Summary of Facility Requirements: |
We will require (1) a CTD/rosette, (2) wench/cable for optics package deployment, (3) sufficient laboratory/bench space for filtrations, optical instruments, analytical instruments, and sorting flow cytometer, (4) deck space/rail space for above-water optical measurements, (5) access to flow through seawater from a system pre-cleaned just before departure, (6) ship crew support during overboard deployments, and (7) coordination between the ship and airborne campaigns. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Choice of ship: (1) budget available to cover ship time for 2 weeks, (2) home port proximity to research area of interest, (3) open ocean measurements
Dates: (1) desire for measurements in summer, (2) avoid early summer period due to persistent cloudiness in Gulf of Maine (compromises airborne campaign), (3) participating scientists are not available after last week of August
Number of days: (1) budget availabilty for simultaneous airborne support, (2) adequate allotment of time to sample a wide range of oceanographic conditions, from optically-complex near shore waters to productive GoM waters, to clear oligotrophic waters. |
