Marine habitat

The Marine System encompasses all coastal areas not appreciably diluted by freshwater (surface salinities seldom falling below 30 ppt), including open coastal areas, straits, and euhaline inland waters.  It can extend from the outer edge of the continental shelf to (1) the landward limit of tidal inundation or wave splash or (2) the seaward limit of the Estuarine System.

Overview

Each year, the Puget Sound Ecosystem Monitoring Program releases the annual Puget Sound Marine Waters Overview report. The latest report combines a wealth of data from comprehensive monitoring programs and provides a concise summary of what was happening in Puget Sound’s marine waters during 2022. The report represents the collective effort of 84 contributors from federal, tribal, state, and local agencies, academia, nonprofits, and private and volunteer groups.
