Science objectives

This is the 16th 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 is providing new insights into coastal ocean processes such as shelf/slope property exchange, air-sea heat 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-14 cruise will consist of 2 legs with distinct objectives.  The main objectives of Leg A are to deploy and recover 3 Coastal Surface Moorings (CSMs), deploy and recover multilple gliders, and deploy 2 AUVs (singly or simultaneously) for ship-attended missions. The main objectives of Leg B are to deploy 5 Coastal Profiler Moorings (CPMs) and recover 7 CPMs. Both 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.

Shipboard Communication

Basic Internet access via HiSeasNet
Is there a need to receive data from shore on a regular basis?
Is there a need to transfer data to shore on a regular basis?


Shipboard Communication Notes: Monitoring of mooring function by connecting to shore-side servers has been found to require more than the normal captive portal data allocation.
