Prioritization of Currently Suitable Brood Rearing Habitat for Mottled Ducks in the Western Gulf Coast

This is a continuous raster dataset identifying wetlands that are currently suitable for mottled duck brood-rearing activities in the Western Gulf Coast. The identification process is based on key biological parameters such as wetland type, number of years inundated, distance to brood nesting habitat, etc. Additionally, this raster dataset presents the data in a form that prioritizes habitat from more suitable to less suitable based on landscape metrics. The scale ranges from 9.9999 to .000005, higher value designating higher suitability ranking.

Prioritization of Wetland Basins for Freshwater Enhancement for Mottled Ducks in the Western Gulf Coast

This is a continuous raster dataset identifying wetland basins/rice fields that are priority for freshwater enhancement to increase the quantity and/or quality of mottled duck brood rearing wetlandsin the Western Gulf Coast. The identification process is based on key biological parameters such as patch size, land use type, distance to brood rearing habitat, etc. Additionally, this raster datasets presents the data in a form that prioritizes habitat from more suitable to less suitable based on landscape metrics. The scale ranges from 1.99to .02, higher value designating higher priority for enhancement.

Research Activities at U.S. Government Agencies in Subsurface Reactive Transport Modeling

The fate of contaminants in the environment is controlled by both chemical reactions and transport phenomena in the subsurface. Our ability to understand the significance of these processes over time requires an accurate conceptual model that incorporates the various mechanisms of coupled chemical and physical processes. Adsorption, desorption, ion exchange, precipitation, dissolution, growth, solid solution, redox, microbial activity, and other processes are often incorporated into reactive transport models for the prediction of contaminant fate and transport. U.S. federal agencies use such models to evaluate contaminant transport and provide guidance to decision makers and regulators for treatment issues. We provide...

USGS Geomagnetism Program: Definitive Disturbance Storm-Time (Dst) Data

A revised version of the storm-time disturbance index Dst is calculated using hourly-mean magnetic-observatory data from four standard observatories and collected over the years 1958–2007. The calculation algorithm is a revision of that established by Sugiura et al., and which is now used by the Kyoto World Data Center for routine production of Dst. The most important new development is for the removal of solar-quiet variation. This is done through time and frequency-domain band-stop filtering – selectively removing specific Fourier terms approximating stationary periodic variation driven by the Earth’s rotation, the Moon’s orbit, the Earth’s orbit around the Sun, and their mutual coupling. The resulting non-stationary...

Prioritization of Areas for Grassland Establishment for Mottled Duck in the Western Gulf Coast

This is a continuous raster dataset identifying areas that are priority for grassland establishment to increase the quantity and/or quality of mottled duck nesting habitat in the Western Gulf Coast. The identification process is based on key biological parameters such as patch size, land use type, distance to brood rearing habitat, etc. Additionally, this raster datasets presents the data in a form that prioritizes habitat from more suitable to less suitable based on landscape metrics. The scale ranges from 1 to 0, higher value designating higher priority for grassland establishment.
