Processes affecting coastal wetland loss in the Louisiana deltaic plain Processes affecting coastal wetland loss in the Louisiana deltaic plain

Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline erosion of 20 m.yr and loss of land area of up to 75 km/yr result from a complex combination of natural (delta switching, subsidence, sea-level rise, storms) and human (flood control, navigation, oil and...

Antarctic glacier-tongue velocities from Landsat images: First results Antarctic glacier-tongue velocities from Landsat images: First results

We measured the velocities of six glacier tongues and a few tongues within ice shelves distributed around the Antarctic coastline by determining the displacement of crevasse patterns seen on sequential Landsat images. The velocities range from less than 0.2 km a−1 for East Antarctic ice-shelf tongues to more than 2.5 km a−1 for the Thwaites Glacier Tongue. All glacier tongues show...

Paper plant effluent revisited-southern Lake Champlain, Vermont and New York Paper plant effluent revisited-southern Lake Champlain, Vermont and New York

We used geologic and geochemical techniques to document the change with time of the distribution and concentration of contaminated bottom sediments in southern Lake Champlain near an International Paper Company plant. Our work, initiated in 1972, was expanded on behalf of Vermont citizens in a class-action suit against the International Paper Company. To update our 1972-1973 results, we...

Radiocarbon ages from two submerged strandline features in the western Gulf of Maine and a sea-level curve for the northeastern Massachusetts coastal region Radiocarbon ages from two submerged strandline features in the western Gulf of Maine and a sea-level curve for the northeastern Massachusetts coastal region

New radiocarbon dates provide ages for two submerged strandline features on the Massachusetts inner shelf. These ages provide limited control on a relative sea-level (RSL) curve for the late Wisconsinan and Holocene. The curve indicates a late Wisconsinan high stand of RSL of +33 m about 14,000 yr ago and a very short-lived relative low stand of about -43 m at about 12,000 yr ago...

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...

Benthic Acoustic Stress Sensor (BASS): Electronics Check-Out Procedures Benthic Acoustic Stress Sensor (BASS): Electronics Check-Out Procedures

Summary The procedures described here are presented so that a technician with limited experience with BASS can perform basic tests which, when executed properly, should be a thorough evaluation of the health of the system. This is not intended as an in depth explanation of how BASS works. Should any significant problems be found, it is suggested that you contact the manufacturer...

Active volcanism beneath the West Antarctic ice sheet and implications for ice-sheet stability Active volcanism beneath the West Antarctic ice sheet and implications for ice-sheet stability

IT is widely understood that the collapse of the West Antarctic ice sheet (WAIS) would cause a global sea level rise of 6 m, yet there continues to be considerable debate about the detailed response of this ice sheet to climate change1-3. Because its bed is grounded well below sea level, the stability of the WAIS may depend on geologically controlled conditions at the base which are...
