The behavior of U- and Th-series nuclides in the estuarine environment The behavior of U- and Th-series nuclides in the estuarine environment

Rivers carry the products of continental weathering, and continuously supply the oceans with a broad range of chemical constituents. This erosional signature is, however, uniquely moderated by biogeochemical processing within estuaries. Estuaries are commonly described as complex filters at land-sea margins, where significant transformations can occur due to strong physico-chemical...

Workshop 3.5: Closing the gap between exposure and effects in monitoring studies Workshop 3.5: Closing the gap between exposure and effects in monitoring studies

A major challenge to contaminant monitoring programs is the selection of an appropriate suite of measurements for assessing exposure and effects. Early monitoring programs relied solely on residue analysis to detect the organochlorine compounds that were in use at that time. A shift to the use of more transient, less persistent chemicals required that a new set of tools be developed to...

The interactive effects of UV-B and insecticide exposure on tadpole survival, growth and development The interactive effects of UV-B and insecticide exposure on tadpole survival, growth and development

Because declines within amphibian populations can seldom be attributed to a single cause, it is important to focus on multiple stressors, both natural and anthropogenic. Variables such as UV-B radiation and chemical contamination can interact with one another in ways that might not be predicted from single-factor studies. We exposed southern leopard frog (Rana sphenocephala) tadpoles to...

Database of historically documented springs and spring flow measurements in Texas Database of historically documented springs and spring flow measurements in Texas

Springs are naturally occurring features that convey excess ground water to the land surface; they represent a transition from ground water to surface water. Water issues through one opening, multiple openings, or numerous seeps in the rock or soil. The database of this report provides information about springs and spring flow in Texas including spring names, identification numbers...

Aquatic synthesis for Voyageurs National Park Aquatic synthesis for Voyageurs National Park

Voyageurs National Park (VOYA), which was established in 1975, contains significant aquatic resources with about 50% of its total area of 883 km2 (341 mi2) consisting of aquatic habitats. In addition to the Park's 30 named lakes, there are numerous wetlands including hundreds of beaver ponds. Due to the Park's size and location in the drainage basin, aquatic resources within the Park are
