The IOOS Association celebrated their second “Ocean Data Day” on June 25th. This year’s theme, Coastal Data for a Strong Economy, recognized the essential role ocean, coastal, and Great Lakes data play in supporting industries, communities, public safety, and the nation’s ocean economy.

Investments in ocean observing are economic multipliers. IOOS data support industries connected to $319 billion in economic activity and 2.1 million jobs nationwide, helping guide ships safely into port, informing fishing operations, strengthening forecasting, and supporting coastal communities across the country.

As part of this year’s recognition, the IOOS Association honored U.S. Representatives Mike Ezell (R-MS-04) and Suzanne Bonamici (D-OR-01) with the IOOS Association Congressional Award for Bipartisan Leadership in Ocean Observing. Their leadership and support have advanced ocean observing and the delivery of critical ocean, coastal, and Great Lakes data that support public safety, coastal resilience, and the nation’s blue economy.

We are also grateful to the strong ocean, coastal, and Great Lakes observing community that we are a part of, and which we help convene. The work that the many data scientists, oceanographers, marine scientists, technicians, modelers, data managers, innovators, Regional Associations, and partners do every day is essential to turning observations into decision-ready information every day.

The U.S. IOOS Advisory Committee held a public meeting June 16-17. The meeting focused on refining the three sets of draft recommendations from the Committee: Observations and Modeling, Private Sector, and Interagency Coordination. Recommendations will be submitted to the NOAA Administrator later this summer once finalized. The Committee also considered three possibilities for future work plans. Minutes from this meeting will be published on the Committee’s website as soon as they are available.
Welcome Ella Scott, who has joined the NOS modeling community this summer as a Lapenta intern! Ella, a rising senior at Vanderbilt University studying Environmental Sociology and Legal Studies, will focus on stakeholder engagement and communications for operational ocean modeling products and tools during her internship.
IOOS funding opportunity under the Ocean Technology Transition Program closes July 15. Visit the U.S. IOOS Ocean Technology Transition website for more information about the program, and find more about the notice of funding opportunity here.

With support from NOAA, the Virginia Institute of Marine Science and partners just completed a 5-year project to build out the Chesapeake Bay Environmental Forecast System. Users can now view longer range forecasts — five days instead of two — and view a forecast about the chance of any harmful algal bloom. They also developed a machine learning-based forecasting model for a HAB species commonly found in the Bay and built a 40 year digital atlas of physical and biogeochemical variables! Read More
The Biodiversity Information Standards (TDWG) Executive Committee has ratified a Conceptual Model and Data Package Guide as additions to the Darwin Core Standard. The Darwin Core Data Package Guide (DwC-DP) specifies how biodiversity data can be formatted in a manner that describes the relationships among the fields in data tables. By basing these relationships on a common Conceptual Model that is not limited by the “star schema” of the existing Darwin Core Archives system, it will be possible to publish complex data sets whose structure is consistent among data providers.
NOAA released its Artificial Intelligence Policy (NAO 216-128). This new administrative order provides essential direction, guidelines, and governance to advance the responsible development and use of AI in support of NOAA’s mission and business objectives. The policy applies to all AI use across the agency, ranging from scientific research, writing, and operations to code development and administrative workflows, and states that all AI applications must be firmly grounded in scientific integrity, accountability, transparency, trustworthiness, and strong risk management.
As part of Hurricane Glider Coordination, Rutgers University developed tools to explore model-data comparisons of NOAA, the U.S. Navy, and European ocean models and glider, Argo, and Fishing Vessel Observing Network data. The Archive Viewer loads the most recent map for a region, and users can view different variables and comparisons or plot profiles. Adaptive sampling guidance compares ocean heat content, sea surface salinity, and current speed from Atlantic basin models to support glider operations. The Transect Plotter allows along-track cross-section comparisons of observations and models.
The NECOFS Casco Bay layers are up on the IOOS Model Viewer! Forecasts include surface and bottom currents, salinity, and temperature.
The Waimea Bay buoy is back online! Moored approximately 4 miles offshore Waimea Bay on the North Shore of Oʻahu, the buoy transmits wave height, direction and period every half hour.
Two NOAA Olympic Coast National Marine Sanctuary (OCNMS) seasonal moorings have been redeployed with real-time capabilities, thanks to technological expertise from NANOOS and funds from the NOAA Climate Program Office and the Washington Ocean Acidification Center! OCNMS has maintained seasonal moorings from Cape Flattery to Grays Harbor since 2000, now designated as a NOAA Ocean Acidification Sentinel Site. Until now, these data could only be accessed after the season. See hourly real-time data from the OCNMS sensors here: Makah Bay and Cape Elizabeth.
The Oregon State University glider team led by NANOOS PI Jack Barth joined the restored historic R/V Western Flyer’s Pacific Northwest expedition to deploy an autonomous underwater glider off the coast of Washington. These glider deployments are a collaboration with the Columbia River Inter-Tribal Fish Commission and the Quinault Indian Nation and provide invaluable data to better understand regional concerns like hypoxia, HABs, and rising water temperatures. Data is available on the NVS Autonomous Vehicle app and learn more about the glider here.
