Dr. Uta Passow describes ECOGIG research on the phenomena known as Marine Snow, with footage from a recent cruise by Dr. Passow and colleagues Dr. Arne Dierks and Dr. Vernon Asper. Oil released in 2010 from the Deepwater Horizon explosion floated upwards, and then some of this oil sank towards the seafloor as part of marine snow. Marine snow are the “dust bunnies” of the ocean. When marine snow sinks it transports microscopic algae and other particles from th sunlit surface ocean to the deep dark ocean, where animals rely on marine snow for food.
