The U.S. Geological Survey hosted the most recent Landsat Science Team Meeting at the Earth Resources Observation and Science Data Center in Sioux Falls, South Dakota from July 7–9. On the first day presentations on the project status were given; this was followed by a day and a half of science presentations by the science team. USGS has made all of the presentations available online.
On the most recent nautical chart of the Beaufort Sea where the long narrow Tapkaluk Islands of Alaska’s North Slope separate the sea from the shallow Elson Lagoon (Nautical Chart 16081) a massive shoal is immediately noticeable just west of the entrance to the lagoon. On the chart it looks like a massive blue thumb jutting out into the sea. The National Oceanographic and Atmospheric Administration (NOAA) identified this prodigious, 6-nautical mile-long, 2-nm-wide shoal using Landsat satellite data.
On Tuesday, Mapbox announced that it is at work incorporating atmospherically corrected Landsat 8 data into its constantly refreshed Landsat-live map. After ironing out a few remaining kinks, data processed through this automatic atmospheric correction will be incorporated into the publicly available Landsat-live layer.
Hydrologists from the University of North Carolina have come up with an innovative way to estimate the size of rivers via satellite images. Combing through data acquired by Landsat satellites, George Allen and Tamlin Pavelsky have compiled a new database of river widths for North America.
Researchers and citizens have known for some time that Turkey’s glaciers are shrinking. Now scientists have calculated the losses and found that more than half of the ice cover in this mountainous country has vanished since the 1970s.
