Publication Highlights Study Shows Drifter Data on Surface Currents Critical to Predict Pollutant Transport 2416

Scientists measured the speed of small, short-lived Gulf surface currents using position data from nearly 300 drifters to determine surface current impact on the dispersion of ocean contaminants. They found that the energy contained in these fluctuating currents makes them primary contributors to the local dispersion and transport of pollutants. Drifter clusters revealed a broad, Read More

Scientists using a high-speed camera to observe bubbles bursting have gained new insight into the hydrodynamics of complex fluids. They found that collapsing bubbles emit a downward spray into the water and that the presence of a surfactant can facilitate the transport of tiny, submicron-diameter oil droplets into the underlying water column. While this phenomenon Read More

Nathan Laxague studies a small-scale subject matter that has potentially large-scale applications. Capillary waves – or ripples – on the ocean surface can indicate the presence of a film or oil slick on the water’s surface, making them “an important link in the chain of oil spill response.” Nathan is a physics Ph.D. student at Read More
