Global sea surface temperature (SST) anomalies are shown on the map for June 8, 2025, where deep red colors indicate SST increases of about 3°C from normal climatological conditions, whereas blue/purple colors indicate cooler SST temperatures. Press the "Play" button in the lower left corner to see the changes in SST anomalies for the past 10 days.
Many nations gather this week for the United Nations (UN) Ocean Conference in Nice, France, which is to "Support the Implementation of Sustainable Development Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development." Satellite data and imagery are integral for tracking changes in the global ocean and informing stakeholders on how to address these changes in the future.
The Sea Surface Temperature Anomalies (L4, MUR) layer is created from the Group for High Resolution Sea Surface Temperature (GHRSST) Sea Surface Temperature Level 4, MUR sea surface temperature analysis product, which uses wavelets as basis functions in an optimal interpolation approach on a global 0.011 degree grid. The version 4 Multiscale Ultrahigh Resolution (MUR) L4 analysis is based upon nighttime GHRSST L2P skin and subskin SST observations from several instruments including the Advanced Microwave Scanning Radiometer-EOS (AMSR-E), the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua and Terra platforms, the U.S. Navy microwave WindSat radiometer, and in situ SST observations from the NOAA iQuam project. The ice concentration data are from the archives at the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF) High Latitude Processing Center and are also used for an improved SST parameterization for the high-latitudes.
