Science objectives

This is the fifteenth 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-15 cruise will consist of 1 to 2 legs as needed to support the equipment to be deployed. The main objectives are to deploy and recover 3 Coastal Surface Moorings (CSMs), deploy 2 Coastal Profiler Moorings (CPMs). Ancillary activities will include CTD casts with water sampling adjacent to moorings, 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. This cruise has been reduced in scope (as was the previous Pioneer-14 cruise) due to the COVID-19 pandemic.

Shipboard Equipment Notes:

Shipboard Communication

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


Shipboard Communication Notes: We need to access data from the moorings on our shore server – both for moorings to be deployed and those in the water.  We have a secondary FleetBroadBand unit that we can use if necessary.
