Jennifer Ruesink, University of Washington professor of biology, studies the relationship between the environment and marine organisms, including eelgrass, the primary species of seagrass that resides in the oceans surrounding Washington. In honor of World Seagrass Day, UW News asked Ruesink to explain what seagrass is and what makes the seagrasses in Washington unique.
Researchers at the University of Washington and the University of Strathclyde report that, in Willapa Bay in Washington state, the water washing over the tidal flats during high tides is largely the same water that washed over the flats during the previous high tide. This “old” water has not been mixed in with “new” water from deeper parts of the bay or the open Pacific Ocean, and has different chemical and biological properties, such as lower levels of food for creatures within the tide flats.
