Mapping the Spatial Dynamics in Optically Significant Nephaloid Layers using Autonomous Underwater Gliders during MIREM.

摘要

Our long-term goal is to develop a coherent understanding of the dynamics and optics of nepheloid layers. To accomplish this, particle composition characteristics will be resolved with the relevant physical forcing mechanisms across a wide range of time and space scales. For the first time, as a result of recent efforts by these investigators, we now have the deployment platform and optical sensing technology that can adequately address this critical problem (Glenn et al. 2004). This work is submitted in collaboration with E. Boss, J. Trowbridge, P. Hill, and T. Milligan (ONR-OB), who are looking at the effects of aggregation and disaggregation on the particle size distribution in nepheloid layers at the Martha's Vineyard Coastal Observatory (MVCO). This work is also in collaboration C. Jones (ONR-PO), who is developing new autonomous sensing capabilities for Mine Counter Measure applications.
