An operational real-time ocean sensor network in the Gulf of Maine

The Gulf of Maine Ocean Observing System (GoMOOS) was established in the summer of 2001 as a prototype real-time observing system that now includes eleven solar-powered buoys with physical and optical sensors, four shore-based long-range HF radar surface current systems, circulation and wave models, satellite observations, and hourly web delivery of data. The Gulf of Maine is a harsh operational environment. Its winter storms pose severe challenges including the build up of sea ice on buoy sensors, superstructure, and solar panels, and in summer its productive waters present severe biofouling problems that can affect the optical sensors. The periods of most difficult operations often coincide with periods of greatest data value in terms of marine safety, search and rescue, and monitoring biological productivity. GoMOOS scientists and engineers continue to refine system designs and operational procedures to moderate the environmental stresses on the sensors and systems.
