Science Objectives

This is the eighth 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-8 cruise will consist of 3 separate legs with distinct objectives. Leg A will focus on ROV operations. The main objectives are to recover 1 surface mooring anchor module and 4 profiler mooring anchors. The main objectives of Leg B are to deploy and recover 3 Coastal Surface Moorings (CSMs), deploy up to 8 and recover up to 6 Coastal Pioneer (CP) Gliders, and deploy 2 AUVs (singly or simultaneously) for ship-attended missions. The main objectives of Leg C are to deploy and recover 5 Coastal Profiler Moorings (CPMs). All three legs will involve ancillary activities, including CTD casts with water sampling adjacent to moorings, gliders and AUVs, comparison of buoy and shipboard data, cross-shelf CTD surveys in the vicinity of the moored array, and surveys using shipboard sensors (ADCP, EK-80, thermosalinograph, multibeam) in the Pioneer moored array region.
