The plume of Mississippi and Atchafalaya River system (MARS) is normally confined to the continental shelf
and extends westward. During March 2010, while weather in North America was dominated by unu...
The spectral slope coefficient of chromophoric dissolved organic matter (S275–295)asa tracer of terrigenous dissolved organic carbon in river-influenced ocean margins

We examined the dispersal of larvae (glochidia) of a common unionid mussel species, Actinonaias ligamentina,
which need to attach to a host fish in order to develop into juveniles, in a lowland river...
The Noutidal Flow in the Providence River of Narragansett Bay：A Stochastic Approach to Estuarine Circulation
Noutidal Flow Narragansett Bay Providence River Estuarine Circulation
font style='font-size:12px;'>
2009/3/7
Atmospherically driven flow in the Providence River (a partially mixed estuary) has been examined using a 51-day velocity record measured 2 m from the bottom. Velocity fluctuations at time scales betw...
Non-Tidal Variability in the Chesapeake Bay and Potomac River：Evidence for Non-Local Forcing
Non-Tidal Variability Chesapeake Bay Potomac River Non-Local Forcing
font style='font-size:12px;'>
2009/2/23
Non-tidal variability in the Chesapeake Bay and Potomac River, and its relation to atmospheric forcing, is examined from two-month sea level and bottom current measurements. The dominant sea level flu...
Circulation Induced by River Inflow in Well Mixed Water over a Sloping Continental Shelf
River Inflow Sloping Continental Shelf Well Mixed Water

2009/1/21
The pressure field over a sloping continental shelf subject to freshwater runoff at the coast can be resolved into a nearly two-dimensional dynamic height field and a residual field, the latter arisin...
The Influence of Wind Stress and River Runoff on a Shelf-Sea Front
Wind Stress River Runoff Shelf-Sea Front
