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 ...
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 ...
Development of a Coupled Ocean–Atmosphere–Wave–Sediment Transport (COAWST) Modeling System
(Elsevier B.V., 2010-07-29)
Understanding the processes responsible for coastal change is important for managing our coastal resources, both natural and economic. The current scientific understanding of coastal sediment transport and geology suggests ...
Shoaling of nonlinear internal waves in Massachusetts Bay
(American Geophysical Union, 2008-08-19)
The shoaling of the nonlinear internal tide in Massachusetts Bay is studied with a fully nonlinear and nonhydrostatic model. The results are compared with current and temperature observations obtained during the August ...
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”

Storm-driven sediment transport in Massachusetts Bay
(Elsevier B.V., 2007-09-22)
Massachusetts Bay is a semi-enclosed embayment in the western Gulf of Maine about 50 km wide and 100 km long. Bottom sediment resuspension is controlled predominately by storm-induced surface waves and transport by the ...
Modeled alongshore circulation and force balances onshore of a submarine canyon
(John Wiley & Sons, 2015-03-23)
Alongshore force balances, including the role of nonlinear advection, in the shoaling and surf zones onshore of a submarine canyon are investigated using a numerical modeling system (Delft3D/SWAN). The model is calibrated ...
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; ...
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 ...
