Moored Observations to Define the Structure and Energetics of Non- Linear Internal Wave Generation over the New Jersey Shelf

摘要

Non-Linear Internal Wave (NLIW) packets are ubiquitous, yet they arrive with a high degree of irregularity in coastal oceans. Through this award, three water-column moorings and four bottom landers were deployed during the New Jersey Shelf Shallow Water 2006 (SW06) experiment. These moorings span the generation region for NLIWs and have been used to (1) quantify the structure, energetics, and timing of O(100) wave packets, (2) elucidate wave formation, the process internal tide steepening, (3) understand what sets the conversion efficiency between barotropic tide, baroclinic tide, and NLIW packets, and (3) determine the external factors (seasonal/mesoscale/tidal) that control NLIW energetics and variability in the coastal environment.
