Adule Golden Eagle (Landscape)
A USGS biological science technician holds an adult golden eagle (Aquila chrysaetos) ready for release. The USGS uses solar-powered GPS tags and special 3-D mapping techniques to track the eagles' movements across the landscape.

Photograph of shallow-water coral bleaching at Sombrero de Pelo reef
Photograph of shallow-water coral bleaching at Sombrero de Pelo reef in Pacific Panama during the 2015-2016 El Nino event. Because of the influence of internal waves, corals growing at deeper locations at this site did not bleach.

Coffee Farm in Puerto Rico
Typical mountain mixed coffee farm operation in Puerto Rico. Climate models project drying conditions in the US Caribbean which would have signficiant effects on moisture-sensitive species such as many endemic frogs.

Aquaculture in Armenia
The growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin of Armenia. The USGS is working with partners, including USAID, to develop scientific tools for water-resource managers to understand and predict consequences of management decisions in Armenia.

Field Training in Armenia
Field training provided by the U.S. Geological Survey on measuring the hydraulic head (water level) above land surface using a pressure gage for a flowing well in Sis, Armenia. The well owner stated that the pressure and discharge have decreased markedly in the last few years.
