The O-Buoy project is a collaborative effort to develop an autonomous buoy to measure atmospheric chemistry. The O-Buoy has evolved considerably from the first concept (left below) to the buoy that was installed in February 2009 (right below). The buoy has several components including the main buoy housing, a floatation collar, and a mast where instruments are mounted. The power system was a joint development by Purdue University and the U.S. Army Cold Regions Research and Enginerring Laboratory.

The project Website with detailed information about the instrumentation and power system. The site has many photos of the buoy structure and deployment.
International has developed a communications controller, utilizing a
low power single board computer running Linux, and an Iridium A3LA-SA
transceiver. This system provides scheduled data transfers from the
buoy along with updates uploaded to the instruments.
