Because the ocean covers 71 percent of Earth's surface, scientists record sea surface temperature (SST) to understand how the ocean communicates with Earth's atmosphere. SST provides fundamental information on the global climate system. SST is an essential parameter in weather prediction and atmospheric model simulations, and is also important for the study of marine ecosystems.
On July 15, 1942, German submarine U-576 sank the freighter SS Bluefields, just before the merchant ship convoy and its U.S. military escorts returned fire and sank the U-boat minutes later off of Cape Hatteras, North Carolina. Both the Bluefields and U-576 remained undisturbed until their discovery by NOAA in 2014. Through September 5, NOAA and its partners will revisit the remains of the two ships.
One hundred years ago, President Woodrow Wilson signed into law an act creating the U.S. National Park Service. Our national parks are magnificent places where we gather with our family, friends and neighbors to experience our nation's most stunning land- and seascapes. While many of us are familiar with the national treasures managed by the National Park Service, you might not know another vast system of parks exists. Only, they're underwater.
