Fundamental challenges to methane recovery from gas hydrates Fundamental challenges to methane recovery from gas hydrates

The fundamental challenges, the location, magnitude, and feasibility of recovery, which must be addressed to recover methane from dispersed hydrate sources, are presented. To induce dissociation of gas hydrate prior to methane recovery, two potential methods are typically considered. Because thermal stimulation requires a large energy input, it is less economically feasible than...

Coastal vulnerability assessment of Virgin Islands National Park (VIIS) to sea-level rise Coastal vulnerability assessment of Virgin Islands National Park (VIIS) to sea-level rise

A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise within Virgin Islands National Park on St. John in the US Virgin Islands. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of relative sea-level rise, historical...

Early to middle Jurassic salt in Baltimore Canyon trough Early to middle Jurassic salt in Baltimore Canyon trough

A pervasive, moderately deep (5-6 s two-way traveltime), high-amplitude reflection is traced on multichannel seismic sections over an approximately 7500 km² area of Baltimore Canyon Trough. The layer associated with the reflection is about 25 km wide, about 60 m thick in the center, and thins monotonically laterally, though asymmetrically, at the edges. Geophysical characteristics are...

Submarine groundwater discharge to a small estuary estimated from radon and salinity measurements and a box model Submarine groundwater discharge to a small estuary estimated from radon and salinity measurements and a box model

Submarine groundwater discharge was quantified by a variety of methods for a 4-day period during the early summer of 2004, in Salt Pond, adjacent to Nauset Marsh, on Cape Cod, USA. Discharge estimates based on radon and salinity took advantage of the presence of the narrow channel connecting Salt Pond to Nauset Marsh, which allowed constructing whole-pond mass balances as water flowed in...

Simulating the evolution of coastal morphology and stratigraphy with a new morphological-behaviour model (GEOMBEST) Simulating the evolution of coastal morphology and stratigraphy with a new morphological-behaviour model (GEOMBEST)

A new morphological-behaviour model is used to simulate evolution of coastal morphology associated with cross-shore translations of the shoreface, barrier, and estuary. The model encapsulates qualitative principles drawn from established geological concepts that are parameterized to provide quantitative predictions of morphological change on geological time scales (order 10 3 years), as...

The kinematic and hydrographic structure of the Gulf of Maine Coastal Current The kinematic and hydrographic structure of the Gulf of Maine Coastal Current

The Gulf of Maine Coastal Current (GMCC), which extends from southern Nova Scotia to Cape Cod Massachusetts, was investigated from 1998 to 2001 by means of extensive hydrographic surveys, current meter moorings, tracked drifters, and satellite-derived thermal imagery. The study focused on two principal branches of the GMCC, the Eastern Maine Coastal Current (EMCC) that extends along the...

Toxic Alexandrium blooms in the western Gulf of Maine: The plume advection hypothesis revisited Toxic Alexandrium blooms in the western Gulf of Maine: The plume advection hypothesis revisited

The plume advection hypothesis links blooms of the toxic dinoflagellate Alexandrium fundyense in the western Gulf of Maine (GOM) to a buoyant plume derived from river outflows. This hypothesis was examined with cruise and moored-instrument observations in 1993 when levels of paralytic shellfish poisoning (PSP) toxins were high, and in 1994 when toxicity was low. A coupled physical...

Vertical motions of the Puerto Rico Trench and Puerto Rico and their cause Vertical motions of the Puerto Rico Trench and Puerto Rico and their cause

The Puerto Rico trench exhibits great water depth, an extremely low gravity anomaly, and a tilted carbonate platform between (reconstructed) elevations of +1300 m and -4000 m. I argue that these features are manifestations of large vertical movements of a segment of the Puerto Rico trench, its forearc, and the island of Puerto Rico that took place 3.3 m.y. ago over a time period as short...

Physical properties of sediment containing methane gas hydrate Physical properties of sediment containing methane gas hydrate

A study conducted by the US Geological Survey (USGS) on the formation, behavior, and properties of mixtures of gas hydrate and sediment is presented. The results show that the properties of host material influence the type and quantity of hydrates formed. The presence of hydrate during mechanical shear tests affects the measured sediment pore pressure. Sediment shear strength may be...

Catastrophic meltwater discharge down the Hudson Valley: A potential trigger for the Intra-Allerød cold period Catastrophic meltwater discharge down the Hudson Valley: A potential trigger for the Intra-Allerød cold period

Glacial freshwater discharge to the Atlantic Ocean during deglaciation may have inhibited oceanic thermohaline circulation, and is often postulated to have driven climatic fluctuations. Yet attributing meltwater-discharge events to particular climate oscillations is problematic, because the location, timing, and amount of meltwater discharge are often poorly constrained. We present...

Surficial geology of the sea floor in west-central Long Island Sound as shown by sidescan-sonar imagery Surficial geology of the sea floor in west-central Long Island Sound as shown by sidescan-sonar imagery

We used sidescan-sonar imagery detailing almost 300 km2 of the sea floor in west-central Long Island Sound in conjunction with bathymetry, sediment samples, bottom video, and seismic data to interpret the area's surficial geology. The distribution of sediments and sedimentary environments interpreted from these data sets represents the Quaternary geology, regional bathymetry, and effects...
