Diffusion sampler testing at Naval Air Station North Island, San Diego County, California, November 1999 to January 2000 Diffusion sampler testing at Naval Air Station North Island, San Diego County, California, November 1999 to January 2000
Volatile organic compound concentrations in water from diffusion samplers were compared to concentrations in water obtained by low-flow purging at 15 observation wells at the Naval Air Station North Island, San Diego, California. Multiple diffusion samplers were installed in the wells. In general, comparisons using bladder pumps and diffusion samplers showed similar volatile organic...

Pattern and process of land loss in the Mississippi Delta: A spatial and temporal analysis of wetland habitat change Pattern and process of land loss in the Mississippi Delta: A spatial and temporal analysis of wetland habitat change
An earlier investigation (Turner 1997) concluded that most of the coastal wetland loss in Louisiana was caused by the effects of canal dredging, that loss was near zero in the absence of canals, and that land loss had decreased to near zero by the late 1990s. This analysis was based on a 15-min quadrangle (approximately 68,000 ha) scale that is too large to isolate processes responsible...

The ecological condition of estuaries in the Gulf of Mexico The ecological condition of estuaries in the Gulf of Mexico
The Gulf of Mexico is a vast natural resource encompassing the coastal areas of western Florida, Alabama, Mississippi, Louisiana, and Texas, as well as a portion of Mexico. Many estuaries flow into the Gulf of Mexico and serve as nursery grounds for fish, habitat for a wide variety of wildlife, shipping routes, and a source of recreation. Estuarine-dependent species constitute more than...
