Using GIS to analyze animal movements in the marine environment Using GIS to analyze animal movements in the marine environment
Advanced methods for analyzing animal movements have been little used in the aquatic research environment compared to the terrestrial. In addition, despite obvious advantages of integrating geographic information systems (GIS) with spatial studies of animal movement behavior, movement analysis tools have not been integrated into GIS for either aquatic or terrestrial environments. We...

Variation in aluminum, iron, and particle concentrations in oxic ground-water samples collected by use of tangential-flow ultrafiltration with low-flow sampling Variation in aluminum, iron, and particle concentrations in oxic ground-water samples collected by use of tangential-flow ultrafiltration with low-flow sampling
Particulates that move with ground water and those that are artificially mobilized during well purging could be incorporated into water samples during collection and could cause trace-element concentrations to vary in unfiltered samples, and possibly in filtered samples (typically 0.45-um (micron) pore size) as well, depending on the particle-size fractions present. Therefore, measured

Alteration of reactive mineral surfaces by ground water Alteration of reactive mineral surfaces by ground water
Two different investigations of shallow sandy aquifers inform our thinking about the role of reactive iron minerals in hydrogeological systems. Ground water in a number of settings has been described as having elevated concentrations of dissolved iron in anoxic portions of contaminant plumes (e.g. Baedecker et al., 1993; Lyngkilde and Christensen, 1992), and the coupling of microbial...

Analysis of USVI coastal feature products from the 1980s and 1990s Analysis of USVI coastal feature products from the 1980s and 1990s
The authors have used color stereo photos along with a three-dimensional visualization photogrammetric software package, Socet Set, to produce orthophotometric-corrected mosaics of St. Croix, St. John, and St. Thomas in the U.S. Virgin Islands. These mosaics are used for numerous applications such as characterization of the shallow water benthic habitat, terrestrial habitat...
