Science Objectives

This is the twelfth 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-12 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. If time and conditions permit, Leg A will include test deployments of a small ROV (Saab Seaeye Falcon). The main objectives of Leg B are to deploy 5 CPMs and recover 7 CPMs. In addition, Leg B will use the Falcon ROV to recover 1 CSM anchor and 1 CPM anchor and line pack. 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.

Other Science Vans:

Shipboard Equipment

Bathymetry System 12 kHz
ADCP 300 kHz
ADCP 150 kHz
Deionized Water System
Science Underway Seawater System
12 kHz Pinger for Wire Use
Fume Hood
EK80 Sonar

Shipboard Equipment Notes: 12 kHz pinger only in the unlikely event of dragging. USBL navigation is for ROV.

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 that the normal captive portal data allocation.

CTD/Water Sampling

911+ Rosette 24-position, 10-liter bottle Rosette with dual T/C sensors
Biospherical underwater PAR (1000m depth limit) with reference Surface PAR
