Eddies are slow-moving swirls of water, or circular ocean currents, that can be tens to hundreds of miles across. They can rotate clockwise or counter-clockwise. Pacific Islands Fisheries Science Center scientists Dr. Phoebe Woodworth-Jefcoats and Dr. Donald Kobayashi contributed to a new study showing that catch rates in Hawaiʻi’s longline fishery are higher in these clockwise eddies than elsewhere in the ocean. The study suggests that these eddies have a higher abundance of prey across the food web—from phytoplankton to fish.
