As part of a funded climate project to extend marine hazard information to week two and beyond, with a focus on oceanic waves, the principal investigator, Dr. Ricardo Martins Campos, has concluded a 20-year wave reforecast using GEFSv12 wind forcings. The reforecast information, along with a more detailed description, is available at the web sites below.  We are happy to have generated a long wave reforecast dataset by joining the efforts of multiple centers, including OPC, EMC, CPC, and AOML/CIMAS.

The first publicly available 20-year wave reforecast dataset, which includes extensive validation and discussions on its performance, has been released! This reforecast provides valuable insights for improving wave forecasts, particularly in extreme weather events. It offers a reliable reference for both research and operational applications, enhancing the understanding and prediction of ocean wave conditions over time.

Since 2011, large accumulations of Sargassum is a recurrent problem in the Caribbean Sea, Gulf of America, and tropical Atlantic Ocean. These events can cause significant economic, environmental and public health harm. AOML developed experimental Sargassum Inundation Reports (SIR) to provide an overview of the risk of Sargassum coastal inundation in the Caribbean and Gulf regions. SIR is the result of the collaboration between the Atlantic Oceanographic and Meteorological Laboratory (NOAA/AOML), NOAA/CoastWatch/OceanWatch, and USF. To view the reports, click here.

For anyone who would like to contribute with a report of Sargassum sighting, please go to this page.
