Pioneer (Offshore). CP04OSSM, High-Power Surface Mooring

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. The Pioneer Offshore Surface Mooring is located on the Continental Slope approximately 450 meters deep. The Continental Shelf-Slope area off the New England coast is a highly productive area and one that is located at a dynamic intersection where ocean currents meet in weather-like “fronts,” and where nutrients, pollutants, and other properties are exchanged between the coast and the deep ocean. Data from the offshore, slope area help to examine exchanges between the shelf and slope and the shelf ecosystem, as well as provide broader insight into the issues of air-sea gas exchange, including Carbon Dioxide. Like other coastal moorings, the Pioneer Offshore Surface Mooring is specifically designed to examine coastal-scale phenomena and withstand the challenging conditions of shallow coastal environments, including large tidal fluctuations. The Surface Mooring contains a surface buoy floating on the sea surface and instruments located at fixed depths through the water column, and an anchor on the seafloor. The surface buoy provides a platform on which to secure surface instruments, allowing for the collection of data in the air and in the water, as well as an antenna to transmit data to shore via satellite.Velocity Profiler (long range) (ADCPS)--Seafloor Pressure (PRESF)--Single Point Velocity Meter (VELPT)--pCO2 Water (PCO2W)--Seawater pH (PHSEN)--Absorption Spectrophotometer (OPTAA)--CTD Pumped (CTDBP)--Dissolved Oxygen Stable Response (DOSTA)--Bio-acoustic Sonar (Coastal) (ZPLSC)--Single Point Velocity Meter (VELPT)--Modem acoustic (ACOMM)--Seawater pH (PHSEN)--Nitrate (NUTNR)--Spectral Irradiance (SPKIR)--Absorption Spectrophotometer (OPTAA)--3-Wavelength Fluorometer (FLORT)--CTD Pumped (CTDBP)--Dissolved Oxygen Stable Response (DOSTA)--3-Axis Motion Pack (MOPAK)--Hydrogen Sensor (HYDGN)--Bulk Meteorology Instrument Package (METBK)--Hydrogen Sensor (HYDGN)--pCO2 Air-Sea (PCO2A)Site Location: 39.9400, -70.8800; Water Depth: 450 meter
