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 ...

Large internal waves in Massachusetts Bay transport sediments offshore
(Elsevier B.V., 2006-09-26)
A field experiment was carried out in Massachusetts Bay in August 1998 to assess the role of large-amplitude internal waves (LIWs) in resuspending bottom sediments. The field experiment consisted of a four-element moored ...
Coupled atmosphere-ocean-wave simulations of a storm event over the Gulf of Lion and Balearic Sea
(American Geophysical Union, 2012-09-15)
The coastal areas of the North-Western Mediterranean Sea are one of the most challenging places for ocean forecasting. This region is exposed to severe storms events that are of short duration. During these events, significant ...
Quantity, composition, and source of sediment collected in sediment traps along the fringing coral reef off Molokai, Hawaii
(Elsevier B.V., 2006-03-20)
Sediment traps were used to evaluate the frequency, cause, and relative intensity of sediment mobility/resuspension along the fringing coral reef off southern Molokai (February 2000–May 2002). Two storms with high rainfall, ...
Accuracy of a pulse-coherent acoustic Doppler profiler in a wave-dominated flow
(American Meteorological Society, 2004-09)
The accuracy of velocities measured by a pulse-coherent acoustic Doppler profiler (PCADP) in the bottom boundary layer of a wave-dominated inner-shelf environment is evaluated. The downward-looking PCADP measured velocities ...
The impact of Hurricane Sandy on the shoreface and inner shelf of Fire Island, New York : large bedform migration but limited erosion
We investigate the impact of superstorm Sandy on the lower shoreface and inner shelf offshore the barrier island system of Fire Island, NY using before-and-after surveys involving swath bathymetry, backscatter and CHIRP ...
Current subsidence rates due to compaction of Holocene sediments in southern Louisiana
(American Geophysical Union, 2006-06-14)
Relative contributions of geologic and anthropogenic processes to subsidence of southern Louisiana are vigorously debated. Of these, shallow sediment compaction is often considered dominant, although this has never been ...
Tidal asymmetry and residual circulation over linear sandbanks and their implication on sediment transport : a process-oriented numerical study
(American Geophysical Union, 2007-12-22)
A series of process-oriented numerical simulations is carried out in order to evaluate the relative role of locally generated residual flow and overtides on net sediment transport over linear sandbanks. The idealized ...
Sediment transport on the Palos Verdes shelf, California
(Elsevier B.V., 2010-02-01)
Sediment transport and the potential for erosion or deposition have been investigated on the Palos Verdes (PV) and San Pedro shelves in southern California to help assess the fate of an effluent-affected deposit contaminated ...
