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.

Scientists at the Washington Department of Ecology along with many other researchers have spent years studying and debating the problem of low oxygen in Puget Sound. Now, many new developments — technical, scientific and legal — are reaching a critical stage and setting up a framework to make some major decisions. This is part four of a four-part series originally published in the Puget Sound Institute blog.

Now, many new developments — technical, scientific and legal — are reaching a critical stage and setting up a framework to make some major decisions. This four-part series was originally published in the Puget Sound Institute blog and looks back on how we have reached our present condition, including a consideration of possible solutions.

About 83% of the water in Puget Sound comes from the ocean. That brings with it all kinds of benefits, including an ocean-size amount of life-giving nutrients that feed the creatures that live here. But it has one potential drawback. That ocean water is notoriously low in oxygen. Why is that and what does it mean for the future of Puget Sound?
