Science Objectives

This is the sixth major infrastructure deployment and servicing cruise for the Pioneer Array of the National Science Foundation’s Ocean Observatories Initiative (OOI). The Pioneer Array includes 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-6 cruise has multiple main objectives and several ancillary objectives. The main objectives can be grouped into six categories: 1) Deploy 3 Coastal Surface Moorings (CSMs) and recover up to 3 CSMs, 2) Deploy 5 Coastal Profiler Moorings (CPMs) and recover up to 5 CPMs, 3) Deploy 2 Coastal Surface Piercing Profilers (CSPPs), 4) Deploy 6 Coastal Pioneer (CP) Gliders and recover up to 6 CP Gliders, 5) Recover 1 AUV Dock and deploy AUVs for ship-attended missions, 6) Perform field evaluation activities, including CTD casts with water sampling. The ancillary objectives include 1) Compare buoy and shipboard data, 2) Conduct cross-shelf CTD surveys in the vicinity of the moored array, and 3) Conduct surveys using shipboard sensors (ADCP, thermosalinograph, multibeam) in the Pioneer moored array region. Because all equipment cannot be fit on deck, the cruise will involve multiple legs in and out of Woods Hole.
