Organic-carbon sequestration in soil/sediment of the Mississippi River deltaic plain — Data; landscape distribution, storage, and inventory; accumulation rates; and recent loss, including a post-Katrina preliminary analysis
Helaine W. Markewich, Gary R. Buell, Louis D. Britsch, John P. McGeehin, John A. Robbins, John H. Wrenn, Douglas L. Dillon, Terry L. Fries, Nancy R. Morehead
2007, Professional Paper 1686-B
Soil/sediment of the Mississippi River deltaic plain (MRDP) in southeastern Louisiana is rich in organic carbon (OC). The MRDP contains about 2 percent of all OC in the surface meter of soil/sediment in the Mississippi River Basin (MRB). Environments within the MRDP differ in soil/sediment organic carbon (SOC) accumulation rate,...
Bathymetry of Walker Lake, West-Central Nevada

Effects of climatic extremes on ground water in western Utah, 1930-2005
Joseph S. Gates
2007, Scientific Investigations Report 2007-5045
Climatic extremes affect ground-water levels and quality in the basins of western Utah. The five droughts since 1930: 1930-36, 1953-65, 1974-78, 1988-93, and 1999-2004—resulted in much-less-than-average recharge, and the pronounced wet period of 1982-86 resulted in much-greater-than-average recharge. Decreased recharge lowered the ground-water level, and increased recharge raised it. These...
