Project aboard

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 the shelf break 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.
