Vignette 01: The Salish Sea Estuary System, Bert Webber
Institute Publications
The Salish Sea is an estuarine ecosystem. Freshwater from land drainages mixes with the waters of the Pacific Ocean and results in water with a measurable, although sometimes small amount of freshwater. The Salish Sea is among the preeminent estuaries of North America. Estuarine circulation and flow are central to the high biological productivity in the Salish Sea.

Vignette 03: Birds Of The Salish Sea, Rob Butler
Institute Publications
The significance of the Salish Sea comes into focus when we look at the diversity and abundance of its birds and mammals, some of which are globally, continentally, and nationally important. Of particular importance is the diversity and abundance of species on the Fraser River Delta. There are more species of birds on the delta than any comparable area in Canada, and nearly half of all 550 species of birds reported for British Columbia have been seen on the delta. Despite all that has been learned about marine birds and mammals, large areas of the Salish Sea in Canada have …

Vignette 12: The Blob, Nicholas Bond
Institute Publications
A marine heat wave of unprecedented severity, areal extent and duration occurred in the Northeast Pacific Ocean during 2014-2016. This event, known as the “Blob,” had a wide variety of far- ranging effects on physical, chemical, and biological ocean properties. Because the Blob was such a massive perturbation, it represents an attractively large signal for inquiry in the Salish Sea. It represents a dress rehearsal for typical conditions in future decades due to global climate change.

Vignette 07: Stormwater Effluent Exerts A Key Pressure On The Salish Sea, Emily Howe
Institute Publications
One of the primary terrestrial pressures on the Salish Sea estuarine and marine environment is urban stormwater runoff. When rainfall runs across hard, impervious surfaces, rather than soaking into the soil, it picks up and delivers toxic contaminants directly to nearby streams, rivers, and eventually the Salish Sea. In fact, for most toxic substances, surface runoff is the largest contributing source of loading to Puget Sound. Unfortunately, the Salish Sea’s relationship with stormwater effluent is no outlier; stormwater is the fastest growing cause of surface water impairment in the United States as urbanization transitions forested and other natural landscapes to …
State Of The Salish Sea: Executive Summary, Kathryn L. Sobocinski
State Of The Salish Sea: Executive Summary, Kathryn L. Sobocinski
Institute Publications
This report synthesizes information on past, current, and emerging stressors within the Salish Sea estuarine ecosystem. The Salish Sea is a complex waterbody shared by Coast Salish Tribes and First Nations, Canada, and the United States. It is defined by multiple freshwater inputs and marine water from the Pacific Ocean that mix in two primary basins, Puget Sound and the Strait of Georgia. Human impacts are multifaceted and extensive within the Salish Sea, with a regional population of almost 9 million people. Population growth has driven urbanization and development, which in turn has triggered structural changes to the landscape and …

Vignette 20: Fraser River Estuary In Need Of Urgent Intensive Care, Laura Kehoe, Tara G. Martin
Institute Publications
The Fraser River is the lifeline of the Salish Sea, influencing its stratification, circulation, and primary productivity. If we do not take strong action to conserve the Fraser River estuary, two-thirds of the species at risk in this region are predicted to have a less than 50% chance of survival. Many of the region's most iconic species could disappear. Conservation action combined with environmental governance is a pathway for a brighter future for the Fraser River and other highly contested regions.

Section 1: Introduction, Kathryn L. Sobocinski
Institute Publications
Section 1 is an introduction to the report and the Salish Sea as a whole. The introduction provides an overview of the Salish Sea, the concept of "ecosystem health," and a roadmap to the rest of the report.
Vignette 17: Salish Sea Jellyfish, Correigh Greene
Vignette 17: Salish Sea Jellyfish, Correigh Greene
Institute Publications
The Salish Sea is home to a diverse community of gelatinous zooplankton (or "jellies"). In their adult forms, jellies comprise a relatively large proportion of biomass in the Salish Sea. Questions regarding jellyfish abundance and climate variation in the Salish Sea have been difficult to address, in part because of a lack of consistent monitoring. Research presented in this vignette suggests that jellyfish are sensitive to climate signals like marine water temperatures, but do not appear to be systematically increasing in abundance over time. Due to advances in modeling, we may gain a better perspective on the roles jellies play …

Section 2 sets a foundation for understanding the Salish Sea ecosystem by describing its fundamental biophysical processes and structure, including estuarine circulation, ecological productivity, and an overview of several important biogenic habitats.
