Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay

Introduction A series of short piston cores ( 2m) were taken from eleven stations in Florida Bay in May, 1994 by researchers from the U.S. Geological Survey (St. Petersburg, FL., Woods Hole, MA., and Denver CO.) in cooperation with South Florida Water Management District, and the Everglades National Park, and the National Oceanic and Atmospheric Administration (NOAA). Core 6A from Bob...

The influence of Hurricane Andrew on sediment distribution in Louisiana coastal marshes The influence of Hurricane Andrew on sediment distribution in Louisiana coastal marshes

The areal extent and temporal patterns of sediment deposition in delta marshes and shallow water bodies of Louisiana associated with the passage of Hurricane Andrew were determined from sediment traps, marker horizons, and benchmarks deployed for other studies. Data were collected over different time scales from 11 sites representing salt, brackish, and intermediate marshes, shallow...

Population size, trends, and conservation problems of the Double-Crested Cormorant on the Pacific Coast of North America Population size, trends, and conservation problems of the Double-Crested Cormorant on the Pacific Coast of North America

Population size, trends and conservation problems of the Double-crested Cormorant (Phalacrocorax auritus) were collated for the Pacific coast of North America using available data up to 1992. About 54,942 birds currently breed there, including roughly 5,848 (5,622 at 90 coastal colonies and at least 226 at 5 interior colonies) and 49,094 (43,358 at 126 coastal colonies and at least 5,736...

Audit of VSMOW distributed by the United States National Institute of Standards and Technology Audit of VSMOW distributed by the United States National Institute of Standards and Technology

Bright-orange floating matter (possibly algae) has been observed in the United States supply of some ampoules and in one of two 10-L primary glass storage flasks of the isotopic reference water VSMOW (Vienna Standard Mean Ocean Water). Within experimental error, ampoules with and without this orange matter are identical in stable hydrogen and oxygen isotopic composition. Thus, the North...

Continental drilling for paleoclimatic records: Recommendations from an international workshop Continental drilling for paleoclimatic records: Recommendations from an international workshop

The Workshop, entitled "Continental Drilling for Paleoclimate Records", was sponsored by the Past Global Changes (PAGES) Project, a core project of the International Geosphere-Biosphere Programme (IGBP) and by the GeoForschungsZentrum, Potsdam, Germany, in conjunction with the International Continental Drilling Programme (ICDP). The impetus for the meeting was the need for long...

Seafloor environments within the Boston Harbor- Massachusetts Bay sedimentary system: A regional synthesis Seafloor environments within the Boston Harbor- Massachusetts Bay sedimentary system: A regional synthesis

Modern seafloor sedimentary environments within the glaciated, topographically complex Boston Harbor and Massachusetts Bay area have been interpreted and mapped from an extensive collection of sidescan sonar records and supplemental marine geologic data. Three categories of environments are present that reflect the dominant long-term processes of erosion or nondeposition, deposition, and...
