To understand how changes in rainfall and temperature might affect coastal wetlands in the northern Gulf of Mexico, USGS researchers conducted field studies at 10 estuaries in five states (Texas, Louisiana, Mississippi, Alabama, and Florida). The fieldwork took place in a variety of coastal wetland types, including mangroves, marshes, and salt flats.

Historically, the coastal plain of Alaska has been characterized by cloudy or foggy conditions, with only limited summer rain. However, with increasing air temperatures, convective storms are becoming increasingly common.

In the Corn Belt states of the Midwestern U.S., intensive row-cropping surrounds small streams, effectively eliminating riparian cover and habitat. Agricultural activities can have profound effects on the chemical and physical characteristics of small streams.

Outcrop of the Bouse Formation in Chemehuevi Valley, Whipple Mountains, Calfornia in background. The Bouse Formation includes sedimentary deposits that chronicle the first arrival of Colorado River water into desert basins downstream from Grand Canyon. The deposits in Chemehuevi Valley are particularly well-exposed.
