Cold-sensitive mangrove forests have expanded dramatically along Florida’s Atlantic Coast since the mid-1980s, as the frequency of killing frosts has declined, according to a new study based on 28 years of satellite data from the NASA-USGS Landsat program.
Maps often convey our relationship to the world. In this map of the northern San Francisco Bay and surrounding environs, the early development of the region is recorded in detail. The full and arduous title of this map is “Map showing portions of Alameda and Contra Costa counties, city and county of San Francisco, California, carefully compiled from official and private maps, surveys and data.”
Forest conservation is an issue of major concern to communities large and small around the globe. But gathering the monitoring data needed to make the right decisions has proven extremely prohibitive for individuals to entire governments.
Maps often help us manage our world. In 1797, when cartographic engraver and chart publisher William Heatheri released his New Chart of the Mediterranean Sea, he had the needs of sea merchants foremost in mind.
Landsat Science Team member Ted Scambos, a lead scientist at the National Snow and Ice Data Center (NSIDC), will present new satellite-derived measurements pointing to the coldest place on Earth this year at the AGU 2013 Fall Meeting in San Francisco, CA.
Since 1972, the Landsat program has allowed scientists and analysts to observe the world beyond the power of human sight, monitor changes to the land, and detect critical trends in the conditions of natural resources.
