Summary of Field Work: |
Characterization of the relationships among lower and intermediate trophic level marine organisms and physical processes at oceanic fronts and eddies.
This work will consist of the deployment of fixed and mobile platforms, sensor and net towing, and traditional profiling and water sampling. Using near-real time modeling and remote sensing to choose the exact final locations we will deploy a small array of bottom mounted and string moorings to provide a fixed (Eulerian) frame of reference. A Lagrangian profiling drifter will be deployed with the goal of transiting the fixed array. Meanwhile, ship based sampling (stations and towed transects) will probe across physical/biological features. Day and night operations will be required. Ideally the timing of the cruise will coincide with the late spring (early June) secondary production maxima in the Delaware coastal region. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, wire for towing, dynamic positioning, and sufficient deck space/A-frame for mooring deployments/recoveries. Additional equipment may be required, depending on final plans: ADCP, MOCNESS, and/or radioisotope van. |

Explanation of Science Party Requirements and Technician Requirements |
After deployment of several moorings, we will alternate between towing (ISIIS or scan fish) and CTD rosette/water sampling and optical instrumentation casts. |

requirements that could affect choice
of ship in scheduling. |
We will require a CTD rosette with water sampling capabilities and the capacity to deploy (and recover) bottom mounted moorings and to tow an undulating vehicle. We will also deploy (and recover) a freely drifting sensor package (Wirewalker).
