Initial results of high-resolution sea-floor mapping offshore of the New York - New Jersey metropolitan area using sidescan sonar Initial results of high-resolution sea-floor mapping offshore of the New York - New Jersey metropolitan area using sidescan sonar

High-resolution seismic, sidescan-sonar, multibeam bathymetry, and sediment sampling techniques were used to map the surficial geology and shallow subbottom stratigraphy of a segment of the inner shelf and nearshore region of New York-New Jersey metropolitan area. Preliminary analyses of these data provide a sedimentologic framework for addressing a wide range of science and management...

Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies

Sediments from three cores obtained from distinct depositional environments in Lake Baikal, Siberia were analyzed for organic carbon, total nitrogen and lignin phenol concentration and composition. Results were used to examine changes in paleoenvironmental conditions during climatic cycles of the late Quaternary ( 125 ka). Average organic carbon, and total nitrogen concentrations, atomic...

Effect of wave-enhanced bottom friction on storm-driven circulation in Massachusetts Bay Effect of wave-enhanced bottom friction on storm-driven circulation in Massachusetts Bay

Massachusetts Bay is a shallow (35 m average depth) semienclosed embayment, roughly 100 ?? 50 km, which opens into the Gulf of Maine at its eastern boundary. Surface waves associated with winter storm winds from the northeast cause large sediment resuspension events, and wave and circulation fields during these events have a quasi-steady response to the wind stress. Coupled wave...

Maps showing the surficial geology of the Culebra shelf, Puerto Rico Maps showing the surficial geology of the Culebra shelf, Puerto Rico

This study presents the surficial and shallow subbottom geology of the insular shelf around Culebra, Puerto Rico. In view of the need for sand and gravel for construction purposes in the area, we inferred the thickness of unlithified, surficial sediment deposits from high-resolution acoustic-reflection profiles and described seafloor sediment samples collected with a Shipek grab.

Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands

This paper examines the influence of Hurricane Andrew on the sediment budget of an 80-kilometer section of the Louisiana barrier islands west of the modern Mississippi delta. Because long-term bathymetric change has been extensively studied in this area, excellent baseline data are available for evaluating the impact of Hurricane Andrew. Results show that despite the high intensity of...

Massive sediment bypassing on the lower shoreface offshore of a wide tidal inlet: Cat Island Pass, Louisiana Massive sediment bypassing on the lower shoreface offshore of a wide tidal inlet: Cat Island Pass, Louisiana

Analysis of a series of historical bathymetric and shoreline surveys along the Louisiana coast west of the Mississippi River mouth detected a large area of deposition in water depths of 2.0–8.5 m offshore of a 9-km-wide tidal inlet, the Cat Island Pass/Wine Island Pass system. A 59.9 · 106 m3 sandy deposit formed from the 1930s–1980s, spanning 27 km in the alongshore direction...

Iron and manganese oxide mineralization in the Pacific Iron and manganese oxide mineralization in the Pacific

Iron, manganese, and iron-manganese deposits occur in nearly all geomorphologic and tectonic environments in the ocean basins and form by one or more of four processes: (1) hydrogenetic precipitation from cold ambient seawater, (2) precipitation from hydrothermal fluids, (3) precipitation from sediment pore waters that have been modified from bottom water compositions by diagenetic...

Contaminants in the Gulf of Maine-What's here and should we worry? Contaminants in the Gulf of Maine-What's here and should we worry?

The Gulf of Maine is a dynamic environment that has highly variable bottom type and localized depositional and transport processes. It is used and impacted by the people around it who hope to use the marine system for many purposes such as fishing, recreation, housing, sewage and dumped disposal, shipping, recreation, and preservation. In order to identify "pollution", which is defined...
