Plankton form the base of the pelagic marine food web in the Salish Sea, and are eaten by fishes, marine mammals, and seabirds. Plankton include microscopic plants (phytoplankton) and very small animals (zooplankton). This vignette presents an overview of monitoring observations of phytoplankton and zooplankton distribution and biomass in the Strait of Georgia. Climate change may lead to unusual and unexpected patterns of phytoplankton and zooplankton in the future.

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.

Given numerous concerns related to the health of the ecosystem and the possibility of anthropogenic impacts—from population growth to climate impacts, such as sea level rise—scientists, engineers, and planners seek an improved basic understanding of the biophysical behavior of the Salish Sea. The Salish Sea Model (SSM) development was motivated by this urgent need for a comprehensive predictive model that could diagnose water quality issues and concerns and serve as a planning tool in support of Puget Sound restoration efforts. The SSM was developed by the Pacific Northwest National Laboratory in collaboration with the Washington State Department of Ecology (Ecology) …

Section 5 introduces cumulative effects and brings in brief case discussions focused on herring, salmon, and orcas. Understanding the layers of stressors the ecosystem faces is integral to gaining a full picture of declines in ecosystem function.

Section 4: Climate Change: A Global Problem With Local Impacts, Kathryn L. Sobocinski
Institute Publications
Section 4 shifts from the local impacts of urbanization to the locally realized impacts of global climate change, including ocean acidification and sea level rise, followed by evidence of climate change in the ecosystem, ranging from phytoplankton and kelp, to wetlands, salmon, and marine birds.
