Lithology, stratigraphy, and paleoenvironments of the Mobil 312-1 well, Georges Bank Basin, US North Atlantic outer continental shelf Lithology, stratigraphy, and paleoenvironments of the Mobil 312-1 well, Georges Bank Basin, US North Atlantic outer continental shelf
The Mobil 312-1 hydrocarbon exploratory well, southeastern Georges Bank Basin penetrated a section entirely composed of sedimentary rocks that range from Middle to Pliocene age. Carbonates are the dominant lithologies in the intervals at 6096-3444 m, 2560-2096 m and 1067-887 m; siliciclastics make up most of the remaining section. Although inferred paleoenvironments range primarily from...

Anomalous abundances of deep-sea fauna on a rocky bottom exposed to strong currents Anomalous abundances of deep-sea fauna on a rocky bottom exposed to strong currents
Unusually high abundances of sponges and gorgonian corals, covering as much as 25% of the bottom, occur at depths greater than 3.5 km on the Blake Spur, a rocky cliff-dominated feature on the western Atlantic continental margin. This is the first report of such high abundances of megafauna from a non-hydrothermal or otherwise chemosynthetically enriched site in abyssal depths. Animal...

Distribution and effects of shallow gas on bulk estuarine sediment properties Distribution and effects of shallow gas on bulk estuarine sediment properties
Gas bubble are present in sediments covering approximately 30% of the main stem of Chesapeake Bay, with bubbles occurring at the sediment-water interface in 18% of the main stem sediments. This biogenic gas is found either in the sediments in the lower salinity reaches of the Bay, or confined to sediments which overline infilled palaeodrainage channels formed during the Wisconsinan low...

Evaluation of nutrient quality-assurance data for Alexanders and Mount Rock Spring basins, Cumberland County, Pennsylvania Evaluation of nutrient quality-assurance data for Alexanders and Mount Rock Spring basins, Cumberland County, Pennsylvania
A total of 304 nutrient samples were collected from May 1990 through September 1991 to determine concentrations and loads of nutrients in water discharged from two spring basins in Cumberland County, Pa. Fifty-four percent of these nutrient samples were for the evaluation of (1) laboratory consistency, (2) container and preservative cleanliness, (3) maintenance of analyte...

Mineralogy of the silt fraction in surficial sediments from the United States mid-Atlantic shelf, slope and rise Mineralogy of the silt fraction in surficial sediments from the United States mid-Atlantic shelf, slope and rise
An analysis of the abundances and distributions of silt-sized heavy minerals from the U.S. mid-Atlantic outer continental shelf, slope, and rise shows that heavy minerals constitute a substantially greater weight percent of the silt fraction than that of the sand fraction regardless of environment and sediment texture. Concentrations of silt-sized heavy minerals progressively decrease...

Relating results from earthworm toxicity tests to agricultural soil Relating results from earthworm toxicity tests to agricultural soil
The artificial soil tests of the European Economic Community and of the Organization for Economic Cooperation produce data relating earthworm mortality to pesticide concentrations in soil under laboratory conditions. To apply these results to agricultural soils it is necessary to relate these concentrations to amounts of pesticide applied per area. This paper reviews the relevant...
