Ranchers and biologists in Hawai‘i — Keeping a business strong and protecting native forests at Ulupalakua Ranch, Maui
Sumner Erdman, Arthur C. Medeiros, Anthony Durso, Lloyd Loope
2000, Rangelands (22) 33-35
The loss of ranchland to critical habitat has been a major concern to ranchers and other large landowners in recent years. On the island of Maui, a novel approach is in the works which seems to have merit both for conservation of endangered species and for helping a landowner ethically...
Usoi Landslide Dam and Lake Sarez – An assessment of hazard and risk in the Pamir Mountains, Tajikistan
D. Alford, Rudy Schuster
2000, Report
Lake Sarez, which is located in the Pamir Mountains in Tajikistan, was created in 1911. A massive landslide, triggered by an earthquake, blocked the Murgab River valley, creating a natural dam, which was called Usoi. In 1999, the International Decade for Natural Disaster Reduction Secretariat led a mission...

Forces dictating colloidal interactions between viruses and soil
Sandip Chattopadhyay, Robert W. Puls
2000, Chemosphere (41) 1279-1286
The fate and transport of viruses in soil and aquatic environments were studied with respect to the different forces involved in the process of sorption of these viruses on soil particles. In accordance with the classical DLVO theory, we have calculated the repulsive electrostatic forces and the attractive van der...

2000, Open-File Report 2000-239
The Thompson Creek mine is an inactive and abandoned tungsten mine located along Thompson Creek about 10.5 miles (17 km) northwest of Clayton, Idaho (see location map in file LOCATION.PDF). The mine consisted initially of open pit mining of outcrops and later of underground workings accessed by a single adit....

2000, International Journal of Remote Sensing (21) 1987-2021
This paper summarizes the steps taken in the generation of the global 1-km AVHRR land dataset, and it documents an evaluation of the data product with respect to the original specifications and its usefulness in research and applications to date. The evaluation addresses data characterization, processing, compositing and handling issues....

Field estimates of gravity terrain corrections and Y2K-compatible method to convert from gravity readings with multiple base stations to tide- and long-term drift-corrected observations
Donald Plouff
2000, Open-File Report 2000-140
Gravity observations are directly made or are obtained from other sources by the U.S. Geological Survey in order to prepare maps of the anomalous gravity field and consequently to interpret the subsurface distribution of rock densities and associated lithologic or geologic units. Observations are made in the field with gravity...

Depth to bedrock in the upper San Pedro Valley, Cochise County, southeastern Arizona
M. E. Gettings, Brenda B. Houser
2000, Open-File Report 2000-138
The thickness, distribution, and character of alluvial sediments that were deposited in the structural subbasins of the upper San Pedro basin in southeastern Arizona during the late Cenozoic provide important constraints on ground-water availability of the area. Two sedimentary units are recognized; the Oligocene and Miocene Pantano(?) Formation and an...
Ecosystem history of Biscayne Bay and the southeast coast

2000, Fact Sheet 145-96
OverviewThe U.S. Geological Survey is participating in a multi-institutional effort to assess, monitor, and restore the ecosystem of South Florida. Federal, State and local agencies are collaborating to establish a firm scientific basis for land management and water policy issues. Historical changes in South Florida related to rapid population growth...
Ecosystem history of Florida Bay
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 144-96
In the past decade seagrass die-offs, algal blooms, and declining numbers of shellfish and sponges have occurred in Florida Bay. These changes have been attributed to human activities; however, neither the natural patterns of change, nor the pre-human baseline for the environment have been determined. Currently, efforts are underway to...
