Sink or break: Oil increases resistance of phytoplankton aggregates to fragmentation by Kai Ziervogel, Julia A. Sweet, Yixuan Song, Laura Bretherton, Matthew J. Rau, Antonietta Quigg, Uta Passow

“…Using phytoplankton aggregates, we demonstrate that marine snow with oil, termed marine oil snow, had a higher resistance to fragmentation compared to marine snow without oil when exposed to turbulence ex situ. At moderate shear levels, typical of the ocean mixed layer, 17% of marine snow without oil broke, whereas 63% of marine snow fragmented at intermediate shear. …”
