Description: The data shown for each year in these maps depict monthly sea surface temperature (SST) anomalies (°C) calculated based on a 20-year climatological baseline (2000-2020), with the long-term warming trend removed (detrended). Overlaid on the SST anomaly is a contour that outlines the spatial area under marine heatwave conditions for each month. Marine heatwaves were identified as pixels experiencing a monthly sea surface temperature anomaly above the 90th percentile of the seasonal threshold for that pixel (2000-2020 climatological baseline). <br/> <br/> The suite of years shown in the Northeast Ocean Data Portal depict the most recent year for which data are available (2024) and several additional years for which recent marine heatwave patterns were particularly interesting. To view the monthly data for each year, click the Active Layers tab in the table of contents to access the time slider. <br/> <br/> Anomalies were calculated using the Multi-scale Ultra-high Resolution (MUR) Sea Surface Temperature (SST) product, a part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program (<a href='https://podaac.jpl.nasa.gov/MEaSUREs-MUR' target='_blank'>here</a>). Additional information about this project and for more details on how these models are produced and used can be found in the layer metadata and on the Fisheries and Climate Toolkit website. <br/> <br/> This data layer was produced by the <a href='https://fisheriesclimatetoolkit.sdsu.edu/protected-areas' target='_blank'>Fisheries Climate Toolkit</a> (FaCeT) project team to support marine protected area planning and climate-ready management.
