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...

Water Resources Data, Alabama, Water Year 2002 Water Resources Data, Alabama, Water Year 2002
Water resources data for the 2002 water year for Alabama consist of records of stage, discharge, and water quality of streams; stages and contents of lakes and reservoirs; and water levels in wells. This report includes records on both surface and ground water in the State. Specifically, it contains: (1) discharge records for 131 streamflow-gaging stations, for 41 partial-record or...

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

Atlas of interoccurrence intervals for selected thresholds of daily precipitation in Texas Atlas of interoccurrence intervals for selected thresholds of daily precipitation in Texas
A Poisson process model is used to define the distribution of interoccurrence intervals of daily precipitation in Texas. A precipitation interoccurrence interval is the time period between two successive rainfall events. Rainfall events are defined as daily precipitation equaling or exceeding a specified depth threshold. Ten precipitation thresholds are considered: 0.05, 0.10, 0.25, 0.50...

A chronicle of organochlorine contamination in Clear Creek, Galveston and Harris Counties, Texas, 1960-2002, as recorded in sediment cores A chronicle of organochlorine contamination in Clear Creek, Galveston and Harris Counties, Texas, 1960-2002, as recorded in sediment cores
Clear Creek flows through the Texas Coastal Plain from its headwaters southeast of Houston, Texas, to Clear Lake, which empties into Galveston Bay. Segments of Clear Creek were on the State of Texas 303(d) list for 1998, 1999, and 2000 as a result of a fish consumption advisory issued by the Texas Department of Health. One of the contaminants for which the fish consumption advisory was...
