Environmental exposures to agrochemicals in the Sierra Nevada mountain range
James S. LeNoir, Linda Aston, Seema Data, Gary Fellers, Laura McConnell, James Sieber
1999, Conference Paper, Analysis of environmental endocrine disruptors
The release of pesticides into the environment may impact human and environmental health. Despite the need for environmental exposure data, few studies quantify exposures in urban areas and even fewer determine exposures to wildlife in remote areas. Although it is expected that concentrations in remote regions will be low, recent...
Potential endocrine disrupting organic chemicals in treated municipal wastewater and river water
Larry B. Barber, Greg K. Brown, Steven D. Zaugg
1999, Conference Paper, Analysis of environmental endocrine disruptors
Select endocrine disrupting organic chemicals were measured in treated wastewater from Chicago, IL, Minneapolis/St. Paul, MN, Detroit, MI, and Milwaukee, WI, and in the Des Plaines, Illinois, and Minnesota Rivers during the fall of 1997 and the spring of 1998. Emphasis was given to alkylphenolpolyethoxylate (APEO) derived compounds, although 17-??-estradiol,...
Pattern and process of land loss in the Mississippi Delta: A spatial and temporal analysis of wetland habitat change
John W. Day, Gary P. Shaffer, Louis D. Britsch, Denise J. Reed, Suzanne Hawes, Donald R. Cahoon
1999, Conference Paper, Recent research in coastal Louisiana : natural system function and response to human influence : a symposium convened by the Louisiana Universities Marine Consortium, February 3-5, 1998, Lafayette, Louisiana
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...
The ecological condition of estuaries in the Gulf of Mexico
1999, Cooperator Report 620-R-98-004
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,...
Environmental models of mineral deposits- A state of the art
Richard B. Wanty, Byron R. Berger, Geoffrey S. Plumlee
1999, Geologica Hungarica. Series geologica (24) 97-106
Although mineral deposits have been classified by their geologic and mineralogical characteristics for decades, the recognition that mineral deposits also could be classified by their environmental characteristics is relatively new. In the past 5 years, numerous advancements have been made in this subject area, building on the earlier work of...

Integrated use of continuous seismic-reflection profiling and ground-penetrating radar methods at John's Pond, Cape Cod, Massachusetts
C.J. Powers, F.P. Haeni, S. Smith
1999, Conference Paper, Proceedings of the symposium on the application of geophysics to engineering and environmental problems : March 14-18, 1999, Oakland, CA
Continuous seismic-reflection profiling (CSP) and ground-penetrating radar (GPR) surveys were conducted by the U.S. Geological Survey in April 1998 over the northern part of John’s Pond, a glacial kettle pond southeast of Otis Air National Guard Base, Cape Cod, Massachusetts. The surveys were conducted to delineate the types and...
Interaction of soil moisture and seedling shelters on water relations of baldcypress seedlings
Ty Swirin, Hans Williams, Bob Keeland
1999, Conference Paper, Proceedings of the tenth biennial southern silvicultural research conference
Stomata1 conductance, transpiration, and leaf water potential were measured during the 1996 growing season on baldcypress (Taxodium disfichum (L.) Rich.) seedlings. Seedlings were hand-planted from 1-O bareroot stock in mesic and permanently Rooded soil conditions. One-half of all seedlings were fitted with 122-cm tall polyethylene tree shelters, Seedlings were planted 1...
