Pioneer (Mobile). CP05MOAS-AV, AUV

Platform assembly containing data collection instruments/sensors on the Pioneer Array, a network of platforms and sensors operating on the continental shelf and slope south of New England in the Atlantic Ocean. An array of two Autonomous Underwater Vehicles (AUVs) will travel along transects across the shelf-break frontal system extending beyond the mooring array, covering an area approximately 80 x 100 km in size centered on the array of moorings. The primary role of the AUVs is to resolve cross- and along-front “eddy fluxes” due to frontal instabilities, wind forcing, and mesoscale variability. Approximate AUV sampling area boundaries: SE: 39.67°N, 70.25°W SW: 39.67°N, 71.17°W NW: 40.67°N, 71.17°W NE: 40.67°N, 70.25°W AUVs will travel along saw-toothed transects, penetrating the sea surface and diving down to a maximum depth of 600 meters Autonomous Underwater Vehicles (AUVs) are propeller-driven mobile assets. The underwater flight pattern of the AUV can be controlled from shore, making these robots well suited for sampling rapidly changing conditions as their flight pattern can be controlled from shore. Seafloor-mounted docking stations allow AUVs to be deployed for extended time periods.3-Wavelength Fluorometer (FLORT)--Dissolved Oxygen Stable Response (DOSTA)--CTD AUV (CTDAV)--Nitrate (NUTNR)--Velocity Profiler (short range) for mobile assets (ADCPA)--Photosynthetically Available Radiation (PARAD)--3-Wavelength Fluorometer (FLORT)--Dissolved Oxygen Stable Response (DOSTA)--CTD AUV (CTDAV)--Nitrate (NUTNR)--Velocity Profiler (short range) for mobile assets (ADCPA)--Photosynthetically Available Radiation (PARAD)Site Location: 40.1700, -70.7100; Water Depth: 0-600 meter
