Puget Sound Nearshore Environments

Introduction

Eelgrass BedsThe nearshore environment covers the most productive waters of Puget Sound. The nearshore encompasses a wide range of habitat types, from marshes and sandflats to kelp and eelgrass beds and upland areas. Ron Thom, a scientist from Battelle Marine Sciences Laboratory, defines the nearshore as "the intertidal portion of the ecosystem that encompasses the tidally influenced portions of rivers and streams. The nearshore extends down to the depth where light can no longer support photosynthetic plants on the bottom."
