Títol: Near-Surface Water Transport in and around Cape Cod Bay, with application to the potential Pilgrim Nuclear Power Station wastewater release.
Resum: This study was motivated by the recent closing of the power plant and a possible release of accumulated wastewater. The investigation applies several different techniques to the drifter data set, as well as to the output from a high-resolution ocean circulation model, to estimate and quantify various aspects of the circulation and spreading and to investigate their underlying physical drivers. Our goal was two-fold: first, to better understand and predict the fate of the Pilgrim wastewater should it be released; and second, to review, compare, and contrast several useful techniques that can be applied to drifter datasets and model outputs in other parts of the global ocean. Our analysis suggests weaker spreading of the wastewater plume inside the Bay than outside, and sensitivity of the advection pathways to the location of the release. Statistical techniques predicted that part of the plume would likely be advected cyclonically around the inner coastline of the Bay towards the more quiescent eastern regions, while another part of the plume would likely pass close to the tip of Cape Cod and the beaches of the Outer Cape. Transport exhibits strong seasonal variability, and wind forcing acts as one of its dominant drivers
