Atmospheric Forecasting

We partner with experts at the Naval Research Laboratory to run regional forecasts of atmospheric conditions. Three day forecasts of coastal and ocean weather are made with the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS). At a 4-km resolution, covering the ocean from Oregon to Mexico, this model is state of the art for forecasting coastal weather patterns.

High Frequency Radar Stations

As part of the national surface current mapping system, we fund several institutions to collect current measurements with high frequency radar. Radar stations operate continuously and provide near-real-time ocean current measurements which improve ocean forecasts, aid mariners and map oil spills.


Ocean Circulation Forecasts

Two ROMS (Regional Ocean Modeling System) models are currently supported by CeNCOOS. The West Coast ROMS extends from Canada to Mexico at a resolution of 10 km, and the California ROMS spans from the CA-Oregon border to Mexico at a higher 3-km resolution. Both models provide information on sea surface height, water temperature, salinity, and currents.


Shore Station Measurements

CeNCOOS provides near real-time observations of water conditions at the shore throughout central and northern California. Continuous monitoring at sites like these allows researchers to look at long-term trends related to ocean acidification, hypoxia and climate patterns.



Two gliders continuously monitor ocean conditions in the waters offshore of central and northern California. One glider transects CalCOFI Line 66.7 between Monterey Bay and 500 km offshore to the southwest. Another glider, off Humboldt, transects between Trinidad Head and about 300 km offshore, repeating the line every 15-20 days.


HABS Forecasting

Researchers at UC Santa Cruz have partnered with CeNCOOS to make Harmful Algal Bloom (HAB) forecasts for the region. The project produces two-day forecasts of Pseudo-nitzschia blooms and domoic acid probabilities along the California coast.


OA Monitoring at Hog Island Oyster Company

A cutting-edge sensor monitors ocean acidification at Hog Island Oyster Company in Tomales Bay, CA. This monitoring effort is funded the IOOS Marine Sensor Innovation Program and is led by UC Davis Bodega Marine Lab. Information from this sensor will allow researchers to better track the impacts of ocean acidification shellfish aquaculture. This kind of industry-academic partnership is integral to addressing OA and its impacts to California.
