A comprehensive, real-time, ocean observing system that includes an array of moored physical and optical
sensors, shore based long-range CODAR for surface current mapping, numerical circulation and wave modeling,
and satellite observations began operations in 2001. At the heart of the Gulf of Maine Ocean Observing System
is an array twenty two real-time, solar-powered oceanographic data buoys that are rotated at eleven monitoring
sites in the Gulf. Buoys are located at sites chosen for the monitoring of major inflows and the principal features
of the gulf-scale circulation. Additional buoys are deployed within the major bays and estuaries of the Gulf, where
they monitor location conditions and gulf/bay exchanges.
The Gulf of Maine is a harsh environment that has presented numerous challenges to the in situ observing
system. However, the buoy array has evolved into a very reliable real-time system that has delivered time-series
measurements long enough to provide the first indications of seasonal cycles and significant interannual
variability that combine to produce previously unrecorded reversals of the canonical Gulf of Maine circulation
features and contribute to major hydrographic anomalies that affect large regions of the Gulf last for several years.
