Assessment and validation of depressions in digital elevation models from multiple elevation data sources and delineation of depressions, sinking streams, and their watersheds in Tennessee and parts of Kentucky, Virginia, North Carolina, Georgia, Alabama, Assessment and validation of depressions in digital elevation models from multiple elevation data sources and delineation of depressions, sinking streams, and their watersheds in Tennessee and parts of Kentucky, Virginia, North Carolina, Georgia, Alabama,
Closed depressions and sinking streams in karst landscapes pose difficulties for water-resources management, in the construction of roads and other public works, and in hydrologic and hydrogeomorphic analyses. Digital elevation models (DEMs) can be used to identify the location and determine the size and shape of closed depressions, but separating artificial depressions due to error from...
Widespread thiamine deficiency in California salmon linked to an anchovy-dominated marine prey base Widespread thiamine deficiency in California salmon linked to an anchovy-dominated marine prey base
Thiamine (vitamin B1) deficiency in marine systems is a globally significant threat to marine life. In 2020, newly hatched Chinook salmon (Oncorhynchus tshawytscha) fry in California’s Central Valley (CCV) hatcheries swam in corkscrew patterns and died at unusually high rates due to a lack of this essential vitamin. We subsequently investigated the impacts and causes of thiamine...

Mobile River Basin Study
The Mobile River Basin in Alabama, Georgia, Mississippi, and Tennessee is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound...

Geohydrology and Effects of Climate and Pumpage Change on Water Resources of the Aucilla–Suwannee–Ochlockonee River Basin, South-Central Georgia and Adjacent Areas of Florida, Progress and Significant Results, 2006—2007
Episodic droughts and increased pumpage since the mid-1970s have caused unprecedented ground-water level decline in the Upper Floridan aquifer in much of the roughly 8,000 square-mile Aucilla-Suwannee-Ochlockonee (ASO) River Basin. To address concerns about water availability, USGS worked with Georgia Environmental Protection Division to improve understanding of the hydrogeologic framework and...
