0002885 / Yankovsky<br/><br/>The PIs propose a study of various aspects of shelf circulation in the <br/>presence of coastal upwelling. Their approach is to conduct further <br/>analysis using data collected and analyzed as part of a prior award. <br/>The data are from an experiment on the continental shelf in the Middle <br/>Atlantic Bight and included measurements from moored instruments, <br/>repeated ship surveys, drifters and coastal radar. The goals are: to <br/>examine the cross-shelf pathway of upwelled water; to determine the <br/>structure of the mass budget and, in particular, to determine whether <br/>it is 2D or 3D; to determine the potential vorticity budget; and to <br/>determine the tidally rectified flow.
