The Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) spans the coastal waters from Long Island Sound through the Gulf of Maine. NERACOOS's primary mission is to meet end-user needs by delivering real-time data to inform and support maritime safety, national security, strong economies, coastal preparedness, and ocean life in the Northeastern Region.

Distinguishing characteristics of the northeast region:

• Ensure safe navigation and operations for maritime vessels and the U.S. Coast Guard by providing real-time data on ocean conditions to reduce the risks associated with unpredictable conditions and improve safety.
• Drive success for New England’s fishing and aquaculture industry by delivering information on oceanography, plankton populations, ocean chemistry, and other environmental factors that affect short- and long-term planning.
• Inform event response strategies by delivering reliable ocean data to the National Weather Service and other users. Storm forecasts, coastal flood monitoring, and harmful algal bloom detection better equip people and businesses to respond to natural disasters and mitigate risks.
