Laser Sensor Development for Fluorescence Detection of Plastics and other Anthropogenic Compounds Dissolved in Seawater.

摘要

The long-term goal is to build and deploy a highly sensitive, in situ AUV-mounted instrument optimized for distinguishing natural colored dissolved organic matter (CDOM) in seawater as well as locating and identifying plastic and rubber-coated objects, such as mines, in the water column and buried within the seafloor. Oceanographic applications include UV-vis spectral characterization of dissolved and particulate (phytoplankton) fluorescence for remote sensing, plume tracking, and pollution applications. The multi-channel UV laser-induced fluorescence sensor (MUVLIFS) will ultimately be integrated and deployed on an autonomous underwater vehicle (AUV) to enhance strategic and oceanographic applications.
