Science objectives

This cruise represents the fourth major infrastructure service cruise for the Pioneer Array of the National Science Foundation’s Ocean Observatories Initiative (OOI). The Pioneer Array will include a network of moorings and autonomous robotic vehicles to monitor waters of the continental shelf and slope south of New England and, in particular, the shelfbreak front where nutrients and other properties are exchanged between the coast and the deep ocean. Data from the Pioneer Array will provide new insights into coastal ocean processes such as shelf/slope nutrient exchange, air-sea property exchange, carbon cycling, and ocean acidification that are important to the New England shelf, and to continental shelf ecosystems around the world. For further information, see http://www.oceanobservatories.org.

Science Activities

The Pioneer-4 cruise has multiple main objectives and several ancillary objectives. The main objectives can be grouped into seven categories: 1) Deploy 3 Coastal Surface Moorings (CSMs), 2) Recover 2 CSMs, 3) Deploy 5 Coastal Profiler Moorings (CPMs), 4) Recovery 3 CPMs, 5) Deploy 6 Coastal Gliders, 6) Recover 5 Coastal Gliders, 7) Perform field evaluation activities, including CTD casts with water sampling. The ancillary objectives include 1) Compare buoy and shipboard data, 2) Deploy 1 Coastal Surface Piercing Profiler (CSPP), 3) Deploy and operate an AUV, 4) Conduct cross-shelf CTD surveys in the vicinity of the moored array, and 5) Conduct surveys using shipboard sensors (ADCP, thermosalinograph) in the Pioneer moored array region.
