The Olin Raytheon/WHOI SCOPE team is assisting WHOI in the buoy design effort by writing software tools for managing the energy budget of a deployed buoy. Woods Hole Oceanographic Institute (WHOI) scientists are constructing buoys for the Ocean Observatories Initiative (OOI), an NSF funded program that will construct a network of buoys for monitoring physical, chemical, geological, and biological variables in the ocean and on the sea floor. The buoys in development for the OOI by WHOI will be expected to operate for 25 years with annual maintenance. Power for an array of reprogrammable sensors will be dependent on a combination of solar and wind power generation and an on-board fuel cell replenished during the annual maintenance.
