During this time, Tides and Currents will be running on the backup website with limited capability. Click here for more information.

Center for Operational Oceanographic Products and Services


Turning operational oceanographic data into meaningful information for the Nation


CO-OPS provides the national infrastructure, science, and technical expertise to monitor, assess, and distribute tide, current, water level, and other coastal oceanographic products and services that support NOAA's mission of environmental stewardship and environmental assessment and prediction. CO-OPS provides operationally sound observations and monitoring capabilities coupled with operational Nowcast Forecast modeling.

Tides and Currents Map

Tides and Currents Map

The Tides and Currents station map can be used to locate stations that provide water levels, meteorological observations, and current observations, as well as other CO-OPS products.

PORTS<sup>®</sup>

PORTS®

The Physical Oceanographic and Real-Time Measurement System measures and disseminates observations and predictions of water levels, currents, salinity, and meteorological parameters (e.g., winds, atmospheric pressure, air and water temperatures) that mariners need to navigate safely.

Sea Level Trends

Sea Level Trends

The Center for Operational Oceanographic Products and Services has been measuring sea level for over 150 years, with tide stations operating on all U.S. coasts through the National Water Level Observation Network.

Operational Forecast Systems

Operational Forecast Systems

The primary objective of the National Operational Coastal Modeling Program (NOCMP) is to develop and operate a national network of Operational Nowcast and Forecast Hydrodynamic Model Systems (called OFS) to support NOAA's mission goals and priorities.
