The ravages of deforestation, wildfires, windstorms, and insects on global forests are revealed in unprecedented detail in a new study based on data from Landsat satellites. Researchers developed new mapping tools that are the first to document forest loss and gain at high resolution and with a consistent method around the globe. The maps will allow scientists to compare forest changes in different countries and to monitor annual deforestation.
Since each pixel in a Landsat image shows a 30-meter square of land—an area about the size of a baseball diamond—researchers can see enough detail to tell local, regional, and global stories. University of Maryland researcher Matthew Hansen and colleagues analyzed 143 billion pixels in 654,000 Landsat images to compile maps of forest loss and gain between the years 2000 and 2012. Key to the project was a collaboration with a team from Google Earth Engine, who took the models developed at the University of Maryland for processing and characterizing the Landsat data and reproduced them in the Google Cloud. Years of data processing was reduced to days.
In many workplaces, wearing the same outfit as your coworkers would come off as a bit strange. Not so if you happen to be in Antarctica as part of Operation IceBridge. In the photograph below, IceBridge team member Theresa Stumpf, right, and other passengers have just arrived on McMurdo's sea ice runway. They touched down on Nov. 12, 2013 aboard a U.S. Air Force C-17 transport aircraft. In past years, IceBridge campaigns were based in Punta Arenas, Chile. Flying from McMurdo this year will make it possible for the team to survey areas they couldn't during previous missions.
