Correction to “Elastic wave speeds and moduli in polycrystalline ice Ih, sI methane hydrate, and sII methane-ethane hydrate”
(American Geophysical Union, 2009-04-10)
Elastic wave speeds and moduli in polycrystalline ice Ih, sI methane hydrate, and sII methane-ethane hydrate
(American Geophysical Union, 2009-02-27)
We used ultrasonic pulse transmission to measure compressional, P, and shear, S, wave speeds in laboratory-formed polycrystalline ice Ih, sI methane hydrate, and sII methane-ethane hydrate. From the wave speed's linear ...
Geomorphic and stratigraphic evidence for an unusual tsunami or storm a few centuries ago at Anegada, British Virgin Islands
Waters from the Atlantic Ocean washed southward across parts of Anegada, east-northeast of Puerto Rico, during a singular event a few centuries ago. The overwash, after crossing a fringing coral reef and 1.5 km of shallow ...
Size distribution of submarine landslides and its implication to tsunami hazard in Puerto Rico
(American Geophysical Union, 2006-06-13)
We have established for the first time a size frequency distribution for carbonate submarine slope failures. Using detailed bathymetry along the northern edge of the carbonate platform north of Puerto Rico, we show that ...
Exploration of the canyon-incised continental margin of the northeastern United States reveals dynamic habitats and diverse communities
(Public Library of Science, 2015-10-28)
The continental margin off the northeastern United States (NEUS) contains numerous, topographically complex features that increase habitat heterogeneity across the region. However, the majority of these rugged features ...
Assessing sulfate reduction and methane cycling in a high salinity pore water system in the northern Gulf of Mexico
(Elsevier B.V., 2008-05-10)
Pore waters extracted from 18 piston cores obtained on and near a salt-cored bathymetric high in Keathley Canyon lease block 151 in the northern Gulf of Mexico contain elevated concentrations of chloride (up to 838 mM) and ...
A photographic and acoustic transect across two deep-water seafloor mounds, Mississippi Canyon, northern Gulf of Mexico
(Elsevier B.V., 2008-05-21)
In the northern Gulf of Mexico, a series of seafloor mounds lie along the floor of the Mississippi Canyon in Atwater Valley lease blocks 13 and 14. The mounds, one of which was drilled by the Chevron Joint Industry Project ...
Tsunami hazard along the U.S. Atlantic coast
(Elsevier B.V., 2009-03-28)
Assessment of natural hazards typically relies on analysis of past occurrences of similar disaster events. Assessment of tsunami hazard to the Atlantic coast of the Unites States poses a scientific challenge because of the ...
Submarine landslide as the source for the October 11, 1918 Mona Passage tsunami : observations and modeling
(Elsevier B.V., 2008-05-17)
The October 11, 1918 ML 7.5 earthquake in the Mona Passage between Hispaniola and Puerto Rico generated a local tsunami that claimed approximately 100 lives along the western coast of Puerto Rico. The area affected by this ...
Seismic imaging of deep low-velocity zone beneath the Dead Sea basin and transform fault : implications for strain localization and crustal rigidity
(American Geophysical Union, 2006-12-23)
New seismic observations from the Dead Sea basin (DSB), a large pull-apart basin along the Dead Sea transform (DST) plate boundary, show a low velocity zone extending to a depth of 18 km under the basin. The lower crust ...
