The increasing frequency of detection of the widely used gasoline additive methyl tertbutyl ether (MTBE) in both ground- and surface waters is receiving much attention from the media, environmental scientists, state environmental agencies, and federal agencies. At the national level, the September 15,1999, Report of the Blue Ribbon Panel on Oxygenates...

Hawaiian volcanoes are exceptional examples of intraplate hotspot volcanism. Hotspot volcanoes, which frequently host large eruptions and related earthquakes, flank‐failure landslides, and associated tsunamis, can present severe hazards to populated regions. Many studies have focused on subaerial parts of Hawaiian volcanoes, but the deep‐water flanks of the edifices, which can...
Subaqueous lava flow lobes, observed on ROV dives off Hawaii
Susumu Umino, Peter W. Lipman, Sumie Obata
2000, Geology (28) 503-506
Remotely operated vehicle (ROV) KAIKO dives north of Oahu Island, Hawaii, and on the lower south rift zone of Loihi Seamount revealed diverse flow morphologies of submarine lava that correlate with slope and rate of lava delivery. Steep to moderate (>10°) slopes are covered with elongate pillows and narrow pahoehoe...
Conveying multiple, complex themes and classes for natural resource assessments
Elijah Ramsey III, Marshall L. Strong
2000, Geocarto International (15) 31-38
Two methods were used to convey the spatial association between a classified forested landscape, the distribution of a hurricane impact, and the subsequent recovery of the habitat from the storm. The first method used a constant hue matrix with varying intensity to visually represent combinations of impact and recovery magnitudes....

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...

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...

Seismic instrumentation of buildings
Mehmet Çelebi
2000, Open-File Report 2000-157
The purpose of this report is to provide information on how and why we deploy seismic instruments in and around building structures. The recorded response data from buildings and other instrumented structures can be and are being primarily used to facilitate necessary studies to improve building codes and therefore reduce losses...

Preliminary Gulf Coast Coalbed Methane Exploration Maps: Depth to Wilcox, Apparent Wilcox Thickness and Vitrinite Reflectance
Charles E. Barker, Laura R. Biewick, Peter D. Warwick, John R. SanFilipo
2000, Open-File Report 2000-113
Strong economic controls on the viability of coalbed methane (CBM) prospects make coal geometry and coal property maps key elements in identifying sweet spots and production fairways. Therefore, this study seeks to identify the apparent prospective areas for CBM exploration in the Wilcox Group (Paleocene-Eocene) lignite and coalbeds by mapping...
