DOLPHIN

The DOLPHIN (Diving OpticaL Profiler and High-speed Integration Network) is a compact, towed body, integrated sensor system designed for rapid optical surveying and real-time realization of advanced data products. The key DOLPHIN system components are a towed optical and hydrographic instrumentation package, a real-time, automated data integration, processing, and visualization network, and a discrete sampling system designed to continuously pump water from the towed package to the boat for analysis. The goal of the system is to provide optical data sets ideally suited for fulfilling calibration and validation needs for NASA remote sensing applications, including aircraft-based and future space-based lidar technologies. These remotely sensed data help researchers better understand and protect the planet Earth.
