Glacial morphology and depositional sequences of the Antarctic continental shelf
(Geological Society of America, 1995-07)
We propose a simple model for the unusual depositional sequences and morphology of the Antarctic continental shelf. Our model considers the regional stratal geometry and the reversed morphology of the Antarctic continental ...
Refining the model of barrier island formation along a paraglacial coast in the Gulf of Maine
Details of the internal architecture and local geochronology of Plum Island, the longest barrier in the Gulf of Maine, has refined our understanding of barrier island formation in paraglacial settings. Ground-penetrating ...
Flow and geochemistry of groundwater beneath a back-barrier lagoon : the subterranean estuary at Chincoteague Bay, Maryland, USA
(Elsevier B.V., 2009-01-21)
To better understand large-scale interactions between fresh and saline groundwater beneath an Atlantic coastal estuary, an offshore drilling and sampling study was performed in a large barrier-bounded lagoon, Chincoteague ...
A catastrophic meltwater flood event and the formation of the Hudson Shelf Valley
(Elsevier B.V., 2007-01-04)
The Hudson Shelf Valley (HSV) is the largest physiographic feature on the U.S. mid-Atlantic continental shelf. The 150-km long valley is the submerged extension of the ancestral Hudson River Valley that connects to the ...
Smartphone-based distributed data collection enables rapid assessment of shorebird habitat suitability
(Public Library of Science, 2016-11-09)
Understanding and managing dynamic coastal landscapes for beach-dependent species requires biological and geological data across the range of relevant environments and habitats. It is difficult to acquire such information; ...
Effect of roughness formulation on the performance of a coupled wave, hydrodynamic, and sediment transport model
(Elsevier B.V., 2010-03-27)
A variety of algorithms are available for parameterizing the hydrodynamic bottom roughness associated with grain size, saltation, bedforms, and wave–current interaction in coastal ocean models. These parameterizations give ...
Along-shelf current variability on the Catalan inner-shelf (NW Mediterranean)
(American Geophysical Union, 2012-09-22)
We examine the circulation over the inner-shelf of the Catalan Sea using observations of currents obtained from three Acoustic Doppler Current Profilers (two at 24 m and one at 50 m) during March–April 2011. The along-shelf ...
Decadal-timescale estuarine geomorphic change under future scenarios of climate and sediment supply
Future estuarine geomorphic change, in response to climate change, sea-level rise, and watershed sediment supply, may govern ecological function, navigation, and water quality. We estimated geomorphic changes in Suisun ...
Estimating hydrodynamic roughness in a wave-dominated environment with a high-resolution acoustic Doppler profiler
(American Geophysical Union, 2005-06-30)
Hydrodynamic roughness is a critical parameter for characterizing bottom drag in boundary layers, and it varies both spatially and temporally due to variation in grain size, bedforms, and saltating sediment. In this paper ...
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)
