Breath Of The Ocean Calls Fish
ScienceDaily (Mar. 6, 2008) — An ocean odor that affects global climate also gathers reef fish to feed as they "eavesdrop" on events that might lead them to food.
Dimethylsulfoniopropionate (DMSP) is given off by algae and phytoplankton, microscopic one-celled plants that float in the ocean. Release of DMSP usually indicates either that tiny animals in the plankton are feeding on the algae, or that massive growth of algae — an algal bloom — has occurred, said Jennifer DeBose, a UC Davis graduate student and now a researcher with the National Oceanic and Atmospheric Administration’s Flower Garden Banks National Marine Sanctuary in the northwestern Gulf of Mexico.
Once released from the ocean into the atmosphere, derivatives of DMSP promote cloud formation, so clouds reflect more sunlight back into space and cool the Earth.
