“A new NOAA National Ocean Service website will provide mariners near real-time coastal ocean surface current observations and tidal current predictions in coastal waters using high frequency (HF) radar, making marine navigation safer for mariners and commercial shippers. The web-based observations are now available for the Chesapeake and San Francisco Bays in areas vital for marine navigation, with additional locations to follow. The product was made possible by NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) using data from the NOAA-led U.S. Integrated Ocean Observing System (IOOS^®).”
