Welcome to NERACOOS! The Northeastern Regional Association of Coastal Ocean Observing Systems is a component of the national IOOS, spanning coastal waters from the Canadian Maritime Provinces to the New York Bight. Our mission is to make available information to those who use these waters. We provide weather and ocean data to fishers and commercial shippers determining if conditions are safe for passage and to emergency managers issuing storm warnings. We are also advancing efforts to use these data for water quality monitoring, harmful algal bloom predictions and warnings, and coastal flooding and erosion forecasting systems..

As our eyes on the oceans, coasts, and Great Lakes, the Integrated Ocean Observing System (IOOSŪ) is a tool for tracking, predicting, managing, and adapting to changes in our marine environment. IOOSŪ delivers the data and information needed to increase our understanding of our coastal waters so decision makers can take action to improve safety, enhance our economy, and protect our environment. NERACOOS is one of 11 Regional Associations contributing to coastal IOOS, coordinated by NOAA IOOS and assisted by the National Federation of Regional Associations (NFRA).
