The National Oceanic and Atmospheric Administration (NOAA) is an American scientific agency with roots that reach back to 1807. Its mission is to “understand and predict changes in climate, weather, oceans, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources.” Over the years, NOAA has amassed a sizable library of photographs of our natural world, some of which I've selected here. To explore more NOAA photos, be sure to browse their albums on Flickr.
