Impacts of exploratory drilling for oil and gas on the benthic environment of Georges Bank Impacts of exploratory drilling for oil and gas on the benthic environment of Georges Bank
A 3-year monitoring program was performed to assess the impacts of exploratory drilling for oil and gas on the benthic environment of Georges Bank, an important commercial fishery region in the North Atlantic east of Massachusetts, USA. Surficial sediments were sampled for chemical and benthic infaunal analysis and bottom still photographs were taken to document bottom microtopography...

Statistical analysis of factors affecting landslide distribution in the new Madrid seismic zone, Tennessee and Kentucky Statistical analysis of factors affecting landslide distribution in the new Madrid seismic zone, Tennessee and Kentucky
More than 220 large landslides along the bluffs bordering the Mississippi alluvial plain between Cairo, Ill., and Memphis, Tenn., are analyzed by discriminant analysis and multiple linear regression to determine the relative effects of slope height and steepness, stratigraphic variation, slope aspect, and proximity to the hypocenters of the 1811-12 New Madrid, Mo., earthquakes on the...

Preliminary geologic map of the Puu Anahulu quadrangle, Hawaii Preliminary geologic map of the Puu Anahulu quadrangle, Hawaii
Vent deposits and lava flows from Hualalai Volcano and lava flows from Mauna Loa and Mauna Kea Volcanoes cover the Puu Anahulu 7 1/2-minute quadrangle. Hualalai's diffuse north-trending rift zone, marked by the large trachyte cone of Puu Waawaa and several basaltic spatter cones, is located mainly in the southwestern part of the quadrangle. Several Hualalai flows originated in the...

A direct method for calculating instrument noise levels in side-by-side seismometer evaluations A direct method for calculating instrument noise levels in side-by-side seismometer evaluations
The subject of determining the inherent system noise levels present in modem broadband closed loop seismic sensors has been an evolving topic ever since closed loop systems became available. Closed loop systems are unique in that the system noise can not be determined via a blocked mass test as in older conventional open loop seismic sensors. Instead, most investigators have resorted to...
