How can sensing technology for surface water dispersant monitoring be practically implemented to measure droplet size distribution in the event of an accidental oil discharge? That’s the question this week’s tank test set out to answer. During the week-long research project, the Ohmsett staff assisted BSEE and NJIT scientists as they continue to test a variety of sensors to measure droplet size distribution, fluorescence, and determine which approaches are the most successful at evaluating the presence of oil droplets in the water column.
