The network of on-line buoys, jointly exploited by IML (Institut Maurice-Lamontagne, Department of Fisheries and Oceans Canada) and ISMER (Institut des sciences de la mer, Université du Québec à Rimouski), consists of buoys recording a suite of optical, oceanographic, and meteorological parameters. These buoys are equipped with communication systems, allowing the transfer and access to data in real time.

The collected information is used to validate and calibrate satellite images, which provide large-scale information on sea-surface temperature and phytoplankton biomass (chlorophylle a).

The network’s first buoy was moored in 2002 at the Rimouski Station. In 2004, a second buoy was moored at the Shediac Station in the southern Gulf of St. Lawrence, followed in 2005 by buoys at the Banc Beaugé as well as the Gaspé Current and Anticosti Gyre monitoring stations.
