TECHNICAL ABSTRACT: A flow micro-photometer is proposed that can measure absorption and backscatter from single aquatic particles including phytoplankton, detritus and minerals. This instrument will make use of a novel adaptive diaphragm to define an analysis region of interest that exactly matches the size, shape and orientation of each particle being analyzed. A micro-fluidic chip will be used to convey the particles in a sequential fashion through the analysis region of the system. The proposed instrument will be designed to be capable of measuring the transmitted and backreflected light of particles from 0.5 microns to 100 microns in diameter. This tool will measure aquatic optical properties over the wavelength range from 400 nm to 700 nm. The instrument will also provide images of each particle, from which the identification of the type of particle being analyzed is possible, as well as provide morphology information.SUMMARY OF ANTICIPATED RESULTS: The anticipated results of this research are sets of imagery and photometric data from a variety of ocean particles that demonstrate the technical feasibility of the tool and a plan to go forward with a further Phase III commercialization.
