چکیده
First Question: Dredging of channels to keep them open to shipping is a recurring and costly activity, especially in cases where channels have to be deepened and maintained to accommodate larger and deeper-draft vessels. There is also the concern of how to dispose of the dredge spoil. How does the Corps balance the cost of dredging and dredge spoil disposal with NEPA requirements and with the environmental, esthetic and economic concerns of the different stakeholder groups? How does the Corps engage these groups in the process and work with them to design projects that are cost-effective and environmentally sound?

STOCK DEFINITION AND GEOGRAPHIC RANGE The northern Gulf of Mexico (i.e., U.S. Gulf of Mexico) continental shelf bottlenose dolphin stock inhabits waters from 20 to 200 m deep in the northern Gulf from the U.S.-Mexican border to the Florida Keys (Figure 1). Both “coastal” and “offshore” ecotypes of bottlenose dolphins occur in the Gulf of Mexico (Hersh and Duffield 1990; LeDuc and Curry 1998). T...

متن کاملModeling the dynamics and export of dissolved organic matter in the Northeastern U.S. continental shelf
Continental shelves are believed to play a major role in carbon cycling due to their high productivity. To improve our understanding of carbon dynamics on continental margins, a dissolved organic matter (DOM) model was developed and imbedded within an existing coupled ocean circulation-biogeochemical model of the U.S. East coast. A model simulation with the DOM module was compared with the refe...
متن کاملCoastal Ocean Modeling: Processes and Real-time Systems
Introduction The coastal oceans are among the most challenging marine environments in the world. They are subject to the combined geometrical constraints of irregular coastlines and highly variable (steep and tall) bathymetry, and are forced both internally, laterally and surfacially by a complex array of tidal, wind and buoyancy forces on a broad range of space/time scales. The resulting coast...

The intersection of human health and the ocean occurs overwhelmingly in the coastal zone. The coastal zone extends from the upland penetration of tidal rivers to the edge of the continental shelf, which can extend 100 miles or more beyond the coast itself. The world's coastlines, including temperate, tropical, and polar coasts, have been estimated to total about 372,000 miles (Smithsonian Insti...
