Stormy conditions associated with periodic winter cold front passages are closely related to transport of suspended sediment to the continental shelf, coastal erosion, and coastal progradation along shoreline sectors where abundant fine-grained sediments are stored on the inner shelf. Cold front passages occur between October and April on 3 to 5-day cycles. Their typical northwest to southeast direction of approach, large spatial scales, and numerous yearly occurrences (20-30 cycles/year) drive physical processes that cause significant coastal change. Acquisition of both remotely sensed multispectral and high-quality photographic data, collected from altitudes of 1,500, 9,000, and 21,000 m before and after cold front passages, forms a database for evaluating coastal change and suspended sediment transport pathways. Satellite imagery provide a longer term perspective on coastal change. Remotely sensed data sets are augmented with ground truth measurements of coastal configuration, sedimentological framework, and water quality.
