The Pioneer Upstream Offshore Profiler Mooring is located on the Continental Slope (approximately 450 m deep), east (i.e., upstream) of the other Moorings.  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 Profiler Moorings, the Pioneer Upstream Offshore Profiler Mooring contains a Wire-Following Profiler that houses instruments.  The Wire-Following Profiler moves through the water column along the mooring riser, continuously sampling ocean characteristics over a specified depth interval.
