Science Objectives

This is the eleventh 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-11 cruise will consist of 3 separate legs with distinct objectives. The main objectives of Leg A are to recover 1 Coastal Surface Mooring (CSM) anchor frame and 1 Coastal Profiler Mooring (CPM) anchor and line pack using an ROV. Leg A may also deploy 2 CPMs. The main objectives of Leg B are to deploy and recover 3 CSMs, deploy and recover multilple Coastal Pioneer (CP) Gliders, and deploy 2 AUVs (singly or simultaneously) for ship-attended missions. The main objectives of Leg C are to deploy 7 CPMs and recover 5 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.
