Heidi M. Sosik


Heidi Sosik received bachelor and master of science degrees in Civil and Environmental Engineering from MIT in 1988 and a doctorate in Oceanography from Scripps Institution of Oceanography in 1993. She joined the Woods Hole Oceanographic Institution as a Postdoctoral Scholar in 1993 and is now an Associate Scientist in the Biology Department. Her research interests focus on phytoplankton ecology and factors that influence light in the marine environment. She received a Presidential Early Career Award for Scientists and Engineers in 1996 and is currently a joint Fellow of WHOI’s Ocean Life Institute and Coastal Ocean Institute. “Never a dull moment” is an apt description of life for Heidi, whose family—one husband, three kids, two dogs, and a cat—keep her keel even and her sails full through the ups and downs of a career as an oceanographer.

The New Wave of Coastal Ocean Observing

The New Wave of Coastal Ocean Observing

Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse both biologically and physically. The diversity and the high energy of the ecosystem make estuaries remarkably resilient. With a better understanding of these systems, we can reverse

their decline and restore the ecological richness of these valuable, albeit muddy, environments.

Shedding Light on Light in the Ocean

Shedding Light on Light in the Ocean

Light in the ocean is like light in no other place on Earth. It is a world that is visibly different from our familiar terrestrial world, and one that marine animals, plants, and microbes are adapted to in extraordinary ways. Light behaves very differently when it moves from air into water. It moves through the expansive depths of an ocean that is devoid of solid surfaces. These and other factors combine to create an environment that has no equivalent on land.
