| Description |
Overview
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.

SRI
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.
