The marine forecasts issued are based on marine observations and model data. Marine observations include buoy and ship reports. Ship reports are invaluable to the NWS, and are reported through the U.S. Voluntary Observing Ship Project. If you are a mariner, please consider joining the nearly 1,000 volunteer ships from around the world that observe the weather at their location.
