Sedimentary environments within a glaciated estuarine-inner shelf system: Boston Harbor and Massachusetts Bay Sedimentary environments within a glaciated estuarine-inner shelf system: Boston Harbor and Massachusetts Bay

Three modern sedimentary environments have been identified and mapped across the glaciated Boston Harbor estuary and adjacent inner shelf of Massachusetts Bay by means of an extensive set of sidescan sonar records and supplemental bathymetric, sedimentary, subbottom and bottom-current data. 1. (1) Environments of erosion and nondeposition appear on the sonographs either as patterns with...

Lime-mud layers in high-energy tidal channels: A record of hurricane deposition Lime-mud layers in high-energy tidal channels: A record of hurricane deposition

During or immediately following the transit of Hurricane Andrew (August 23-24, 1992) across the northern part of the Great Bahama Bank, thin laminated beds of carbonate mud were deposited in high-energy subtidal channels (4 m depth) through the ooid shoals of south Cat Cay and Joulters Cays. During our reconnaissance seven weeks later, we observed lime-mud beds exposed in the troughs of...

Fluorspar Fluorspar

The U.S. produced 50 kt of fluorspar in 1992 and imported nearly 409 kt. Almost all the fluorspar was imported from China. The U.S. consumption of 467 kt represents the lowest level since 1958. This is due to the continuing decrease in consumption by the steel and aluminum industries.

Resistance of young wolf pups to inclement weather Resistance of young wolf pups to inclement weather

Three observations of young wolf (Canis lupus) pups in Denali National Park and Preserve, Alaska, and two on Ellesmere Island, Northwest Territories, Canada, indicate that pups

Prey escaping wolves, Canis lupus, despite close proximity Prey escaping wolves, Canis lupus, despite close proximity

We describe attacks by wolf (Canis lupus) packs in Minnesota on a white-tailed deer (Odocoileus virginianus) and a moose (Alces alces) in which wolves were within contact distance of the prey but in which the prey escaped.

Sex and age identification of palila Sex and age identification of palila

Methods to sex and age Palila (Loxioides bailleui), an endangered Hawaiian finch restricted to subalpine woodlands on Hawai'i, were identified on the basis of measurements and plumage characteristics of 17 museum specimens and 96 known-age, live Palila. Palila undergo a single annual molt during September-December following the breeding season. Presence of a complete or partial wingbar

Site tenacity of the endangered palila Site tenacity of the endangered palila

Strong site tenacity might prevent Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, from repopulating favorable habitats in their former range. We used radio telemetry during the nonbreeding and breeding seasons to study movements and dispersal rates of 57 Palila. All Palila remained in the study area, and home range sizes and movement distances were small relative to...
