Borehole-wall imaging with acoustic and optical televiewers for fractured-bedrock aquifer investigations Borehole-wall imaging with acoustic and optical televiewers for fractured-bedrock aquifer investigations
Imaging with acoustic and optical televiewers results in continuous and oriented 360 degree views of the borehole wall from which the character and orientation of lithologic and structural features can be defined for fractured-bedrock aquifer investigations. Fractures are more clearly defined under a wider range of conditions on acoustic images than on optical images including dark...

Characterization and disinfection by-product formation potential of natural organic matter in surface and ground waters from Northern Florida Characterization and disinfection by-product formation potential of natural organic matter in surface and ground waters from Northern Florida
Streamwaters in northern Florida have large concentrations of natural organic matter (NOM), and commonly flow directly into the ground water system through karst features, such as sinkholes. In this study NOM from northern Florida stream and ground waters was fractionated, the fractions characterized by infrared (IR) and nuclear magnetic resonance (NMR), and then chlorinated to...

Comparisons of in situ and core gas measurements in ODP Leg 164 bore holes Comparisons of in situ and core gas measurements in ODP Leg 164 bore holes
During Ocean Drilling Program Leg 164, an unprecedented effort was made to determine the amounts of gas and gas hydrate in the sediments from Sites 994, 995, and 997. For the first time in the history of academic drilling, a pressure core sampler (PCS) worked well enough to generate an independent stratigraphy of in situ gas concentrations and compositions with depth. Here, gas...

Comprehensive isolation of natural organic matter from water for spectral characterizations and reactivity testing Comprehensive isolation of natural organic matter from water for spectral characterizations and reactivity testing
A variety of approaches were tested to comprehensively isolate natural organic matter (NOM) from water. For waters with high NOM concentrations such as the Suwannee River, Georgia, approaches that used combinations of membrane concentrations, evaporative concentrations, and adsorption on nonionic XAD resins, ion exchange resins and iron oxide coated sand isolated over 90% of the NOM...

Contribution of landbird migration to the biological diversity of the northwest gulf coastal plain Contribution of landbird migration to the biological diversity of the northwest gulf coastal plain
This study examined seasonal diversity and feeding behavior of those avian species utilizing that region of the Northwest Gulf Coastal Plain known as the Chenier Plain. Field observations were conducted at three forested locations on coastal cheniers for three years (1993-95) in the spring and at one location for three years (1996-98) in autumn to determine species presence and diet. One...

Correlation of offshore seismic profiles with onshore New Jersey Miocene sediments Correlation of offshore seismic profiles with onshore New Jersey Miocene sediments
The New Jersey passive continental margin records the interaction of sequences and sea-level, although previous studies linking seismically defined sequences, borehole control, and global ??18O records were hindered by a seismic data gap on the inner-shelf. We describe new seismic data from the innermost New Jersey shelf that tie offshore seismic stratigraphy directly to onshore...
