Abstract: The present invention provides a novel and unique device, method and system that detects thiocyanate in seawater with the halide ions present that can be provided in a hand-portable device that offers detection limits to 1-2 ppb which at least twice as sensitive as the nearest known device in the current state of the art. The sensor is also sensitive to nitrate ions (NO3?) in seawater at similar ppb concentrations as thiocyanate.

Abstract: A velocimetry apparatus and method for the collection of target-specific images of fluid motions are disclosed. The apparatus includes a camera and a light source. The camera collects and provides images of the fluid showing instantaneous positions of particles in the fluid. The light source provides a light sheet (two-dimensional) or volume (three-dimensional) to illuminate the particles. The camera and the light source are powered by portable energy sources and measure instantaenous velocity of the fluid in a field of view. Shape and distance between first camera, the light source and the portable energy sources are so configured that the apparatus is a self-contained apparatus portable by a diver during operation thereof.
