Acute toxicity of three fire-retardant and two fire-suppressant foam formulations to the early life stages of rainbow trout (Oncorhynchus mykiss) Acute toxicity of three fire-retardant and two fire-suppressant foam formulations to the early life stages of rainbow trout (Oncorhynchus mykiss)
Laboratory studies were conducted with five early life stages of rainbow trout, Oncorhynchus mykiss, to determine the acute toxicities of five fire-fighting chemical formulations in standardized soft and hard water. Eyed egg, embryo–larvae, swim-up fry, and 60- and 90-d posthatch juveniles were exposed to three fire retardants (Fire-Trol LCG-R, Fire-Trol GTS-R, and Phos-Chek D75-F) and...

Interaction of flooding and salinity stress on baldcypress (Taxodium distichum) Interaction of flooding and salinity stress on baldcypress (Taxodium distichum)
Coastal wetlands of the southeastern United States are threatened by increases in flooding and salinity as a result of both natural processes and man-induced hydrologic alterations. Furthermore, global climate change scenarios suggest that, as a consequence of rising sea levels, much larger areas of coastal wetlands may be affected by flooding and salinity in the next 50 to 100 years. In...

Peak-flow frequency and extreme flood potential for streams in the vicinity of the Highland Lakes, central Texas Peak-flow frequency and extreme flood potential for streams in the vicinity of the Highland Lakes, central Texas
The Highland Lakes on the Colorado River are in an area periodically threatened by large storms and floods. Many storms exceeding 10 inches (in.) in depth have been documented in the area, including some with depths approaching 40 in. These storms typically produce large peak discharges that often threaten lives and property. The storms sometimes occur with little warning. Steep stream...

Summary of data-collection activities and effects of flooding from tropical storm Alberto in parts of Georgia, Alabama, and Florida, July 1994 Summary of data-collection activities and effects of flooding from tropical storm Alberto in parts of Georgia, Alabama, and Florida, July 1994
Parts of central and southwestern Georgia, southeastern Alabama, and the western panhandle of Florida were devastated by floods resulting from rainfall produced by Tropical Storm Alberto in July 1994. As tributary floodwaters combined and moved downstream in the Flint, Ocmulgee, and Choctawhatchee Rivers, peak discharges exceeded the 100-year flood discharges along most stream reaches...

Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay
Introduction A series of short piston cores ( 2m) were taken from eleven stations in Florida Bay in May, 1994 by researchers from the U.S. Geological Survey (St. Petersburg, FL., Woods Hole, MA., and Denver CO.) in cooperation with South Florida Water Management District, and the Everglades National Park, and the National Oceanic and Atmospheric Administration (NOAA). Core 6A from Bob...

Direct denitrification in mangrove sediments in Terminos Lagoon, Mexico Direct denitrification in mangrove sediments in Terminos Lagoon, Mexico
Rates of direct denitrification were measured using 15N isotope tchniques in intact sediment cores from fringe and basin mangroves in Terminos Lagoon, Mexico. Sediments were injected with 15NO3- and the distribution of 15N was measured over time in the head space, overlying water, and sediments. Experiments included an investigation of spatial variation in denitrification rates by...
