Florida Integrated Science Center (FISC) Coral Reef Research Florida Integrated Science Center (FISC) Coral Reef Research
Coral reefs provide important ecosystem services such as shoreline protection and the support of lucrative industries including fisheries and tourism. Such ecosystem services are being compromised as reefs decline due to coral disease, climate change, overfishing, and pollution. There is a need for focused, integrated science to understand the complex ecological interactions and effects...

Derivation of ground surface and vegetation in a coastal Florida wetland with airborne laser technology Derivation of ground surface and vegetation in a coastal Florida wetland with airborne laser technology
The geomorphology and vegetation of marsh-dominated coastal lowlands were mapped from airborne laser data points collected on the Gulf Coast of Florida near Cedar Key. Surface models were developed using low- and high-point filters to separate ground-surface and vegetation-canopy intercepts. In a non-automated process, the landscape was partitioned into functional landscape units to...

Mapping of Florida's coastal and marine resources: Setting priorities workshop Mapping of Florida's coastal and marine resources: Setting priorities workshop
The importance of mapping habitats and bioregions as a means to improve resource management has become increasingly clear. Large areas of the waters surrounding Florida are unmapped or incompletely mapped, possibly hindering proper management and good decisionmaking. Mapping of these ecosystems is among the top priorities identified by the Florida Oceans and Coastal Council in their...

Bed-material entrainment and associated transportation infrastructure problems in streams of the Edwards Plateau, central Texas Bed-material entrainment and associated transportation infrastructure problems in streams of the Edwards Plateau, central Texas
The Texas Department of Transportation commonly builds and maintains low-water crossings (LWCs) over streams in the Edwards Plateau in Central Texas. LWCs are low-height structures, typically constructed of concrete and asphalt, that provide acceptable passage over seasonal rivers or streams with relatively low normal-depth flow. They are designed to accommodate flow by roadway...

Estimated Flood-Inundation Mapping for the Upper Blue River, Indian Creek, and Dyke Branch in Kansas City, Missouri, 2006-08 Estimated Flood-Inundation Mapping for the Upper Blue River, Indian Creek, and Dyke Branch in Kansas City, Missouri, 2006-08
In the interest of improved public safety during flooding, the U.S. Geological Survey, in cooperation with the city of Kansas City, Missouri, completed a flood-inundation study of the Blue River in Kansas City, Missouri, from the U.S. Geological Survey streamflow gage at Kenneth Road to 63rd Street, of Indian Creek from the Kansas-Missouri border to its mouth, and of Dyke Branch from the...

Thiamine deficiency effects on the vision and foraging ability of lake trout fry Thiamine deficiency effects on the vision and foraging ability of lake trout fry
The exact causes of the historical recruitment failures of Great Lakes lake trout Salvelinus namaycush are unknown. Thiamine deficiency has been associated with neurological abnormalities in lake trout that lead to early mortality syndrome (EMS) in salmonine swim-up fry, and EMS-related mortality at the swim-up stage is a factor that contributes to the reproductive failure of lake trout

Synthesis of the Hydrogeologic Framework of the Floridan Aquifer System and Delineation of a Major Avon Park Permeable Zone in Central and Southern Florida Synthesis of the Hydrogeologic Framework of the Floridan Aquifer System and Delineation of a Major Avon Park Permeable Zone in Central and Southern Florida
The carbonate Floridan aquifer system of central and southern Florida (south of a latitude of about 29 degrees north) is an invaluable resource with a complex framework that has previously been mapped and managed primarily in a subregional context according to geopolitical boundaries. As interest and use of the Floridan aquifer system in this area increase, a consistent regional...

Estimation of the change in freshwater volume in the North Coast Limestone upper aquifer of Puerto Rico in the Rio Grande de Manati-Rio de la Plata area between 1960 and 1990 and Implications on public-supply water availability Estimation of the change in freshwater volume in the North Coast Limestone upper aquifer of Puerto Rico in the Rio Grande de Manati-Rio de la Plata area between 1960 and 1990 and Implications on public-supply water availability
Ground water in the upper aquifer of the North Coast Limestone aquifer system historically has been the principal source of public-supply and self-supplied industrial water use in north-central Puerto Rico. Development of the aquifer for these two major water-use categories began in about 1930; however, withdrawals did not become an important water-supply source for sustaining local...

Results of the chemical and isotopic analyses of sediment and ground water from alluvium of the Canadian River near a closed municipal landfill, Norman, Oklahoma, part 2 Results of the chemical and isotopic analyses of sediment and ground water from alluvium of the Canadian River near a closed municipal landfill, Norman, Oklahoma, part 2
Analytical results on sediment and associated ground water from the Canadian River alluvium collected subsequent to those described in Breit and others (2005) are presented in this report. The data presented herein were collected primarily to evaluate the iron and sulfur species within the sediment at well sites IC 36, IC 54, and IC South located at the USGS Norman Landfill study site...

Drier forest composition associated with hydrologic change in the Apalachicola River floodplain, Florida Drier forest composition associated with hydrologic change in the Apalachicola River floodplain, Florida
Forests of the Apalachicola River floodplain had shorter flood durations, were drier in composition, and had 17 percent fewer trees in 2004 than in 1976. The change to drier forest composition is expected to continue for at least 80 more years. Floodplain drying was caused by large declines in river levels resulting from erosion of the river channel after 1954 and from decreased flows in...

Total selenium and selenium species in irrigation drain inflows to the Salton Sea, California, October 2007 and January 2008 Total selenium and selenium species in irrigation drain inflows to the Salton Sea, California, October 2007 and January 2008
This report presents the results for two sampling periods (October 2007 and January 2008) during a 4-year monitoring program to characterize selenium concentrations in selected irrigation drains flowing into the Salton Sea, California. Total selenium, selenium species (selenite, selenate, organoselenium), and total suspended solids were determined in water samples, and total selenium was
