CA harmful algae risk mapping (C-HARM)
Full text linkThe CA-Harmful Algae Risk Mapping (C-HARM) system generates predictions of harmful algal bloom (HAB) conditions in California and Southern Oregon coastal waters through a combination of 1) real-time circulation models that predict the ocean physics, i.e. the West Coast Operational Forecast System (WCOFS), 2) satellite remote-sensing data of the ocean “color” and chlorophyll patterns, and 3) statistical models for predicting bloom and toxin likelihoods. These predictions are generated daily to provide a forecast of where you might encounter a Pseudo-nitzschia bloom and/or domoic acid event in the next one to three days
Using gliders to track low dissolved oxygen water in Dungeness crab habitat in partnership with Quinault Indian Nation
Full text linkAutonomous underwater gliders operated by Oregon State University, OSU, in collaboration with the Columbia River Inter-Tribal Fish Commission, CRITFC, and funded by the Northwest Association of Networked Ocean Observing Systems, NANOOS, are monitoring water quality along the central Washington shelf with guidance from the Quinault Indian Nation, QIN. The gliders collect high-resolution data on temperature, salinity, dissolved oxygen, and other water properties, helping identify seasonal hypoxic zones. Data from these missions are visualized on the NANOOS Visualization System, supporting real-time decision-making for fisheries management. These insights allow resource managers to mitigate risks to Dungeness crab populations by identifying low oxygen conditions before they cause mass mortality in crab pots. The collaboration also includes community engagement, such as outreach to Quinault youth, connecting data science and traditional resource stewardship
Ocean Heat Content
Full text linkSeasonal and annual ocean Heat Content time series are calculated using in situ subsurface temperature data aggregated from the across ocean observing systems in the World Ocean Database (WOD)

Surface Currents Data for Search and Rescue, Ocean and Weather Forecasting
Full text linkHigh-Frequency Radar (HFR) systems provide near real-time measurements of surface ocean currents, offering broad and continuous coastal coverage. Supported by CeNCOOS as part of the national U.S. IOOS network, 33 HFR stations across Central and Northern California collect critical data used in applications including search and rescue, maritime navigation, and oil spill response. Data are processed and visualized on the CalOOS Data Portal, with high-resolution coverage in key areas like San Francisco Bay. These systems enhance operational efficiency, reduce emergency response times, and support safer and more informed decision-making along the coast
Marine Exchange of Alaska Automatic Identification System and Weather Station Installations
Full text linkThe Alaska Ocean Observing System (AOOS) has supported the Marine Exchange of Alaska (MXAK) for over 15 years to enhance maritime safety in Alaska by installing and operating 70 terrestrial weather stations in areas that lacked reliable weather intelligence. The MXAK provides the real-time weather information directly to vessels over the Automatic Identification System (AIS) vessel tracking network. The MXAK also equips 16 vessels with weather sensors to build-out automated shipboard weather observing capabilities. All data are made available to NOAA\u27s National Weather Service (NWS) in real-time, supporting Alaska\u27s marine forecasts, situational awareness, weather models, and decision support for the protection of life, property, and enhancement of the national economy
Charleston, SC Branch Pilots Association and NOAA PORTS
Full text linkThe Charleston, SC Branch Pilots Association (end user 1) make “go-no-go” decisions based on data from the National Water Level Observation Network (NWLON), Official NOAA Tide Predictions and Physical Oceanographic Real Time System (PORTS) sensors for tall, deep draft vessels transiting through Charleston Harbor and into the associated tributaries. Data from these sources allows more precise calculations of clearances of at the Don Holt Bridge at North Charleston, SC. The NWLON and PORTS are sponsored by CO-OPS which is the source for accurate, reliable, and timely tides, water levels, currents, and other oceanographic data. The vision of CO-OPS is to support the Nation\u27s economy and safeguard coastal communities with oceanographic information accessible by anyone, at any time, from any place
Blended Sea Winds
Full text linkThe Blended Sea Winds product is a synthesis of observations from multiple satellites (up to seven satellites) to create gridded wind speeds.
The NOAA NCEI Blended Seawinds (NBS) version 2.0 dataset synthesizes observations from multiple satellites (up to seven satellites since June 2002) to create gridded wind speeds (10m, neutral). This is an updated version of the existing NOAA NBS v1.0, which is a global gridded 0.25° and 6-hourly sea surface winds product that has wide applications in marine transportation, marine ecosystem and fisheries, offshore winds, weather and ocean forecasts, and other areas
Regional Ocean Climatologies
Full text linkOcean temperature and salinity data are compiled from the World Ocean Database (WOD), the world’s largest collection of ocean profile data that are available without restriction. There are several downstream uses of this Database, ranging from scientific research of climate to initial conditions for climate forecasts and projections
Penobscot Bay & River Pilots Association: Moving Large Ships within a Complex Coastal Environment in a Safe and Timely Manner
Full text linkThe central coast of Maine is a convergence of marine commerce. The lucrative lobster fishery, ocean-based tourism, recreation, cargo shipping, and cruise ships all commingle amidst an intricate geography of bays, harbors, fjords, islands, and rivers. Throughout this complex coastline is a series of commercial, industrial, and residential ports – including Rockland, Belfast, Stonington, Bar Harbor, Bucksport, Searsport, and Bangor – that rely on safe and timely vessel transit. The Penobscot Bay & River Pilots Association (PBRPA) has the critical responsibility of safely moving cruise ships, tankers ships, and other large vessels to port through this maritime epicenter. To do their job, PBRPA relies on a network of ocean observing assets that deliver real-time data on sea state and weather and support oceanographic and meteorological forecast models
