Regional And Temporal Variability In Puget Sound Zooplankton: Bottom-Up Links To Juvenile Salmon, Julie Keister, Julia Bos, Bethellee Herrmann, Mya Keyers, Christopher Krembs, John Mickett, J. A. (Jan A.) Newton, Wendi Reuf, Amanda Winans

Salish Sea Ecosystem Conference

We use data from the Puget Sound Zooplankton Monitoring Program to explore patterns of spatial and interannual variability in zooplankton communities in response to environmental change during 2014-2017. This program is a collaborative effort involving 10 tribal, county, state, federal, academic, and nonprofit entities initiated via the Salish Sea Marine Survival Project with the goal of understanding the key role of zooplankton in food webs and ecosystems. Large interannual differences in the environment over this period strong effects on zooplankton community structure and abundance. 2014 began as a fairly normal year in Puget Sound until the Pacific Warm Anomaly event …


Zooplankton Variability In The Northern Salish Sea Over The Past 3 Decades, And Relationships With Coho Salmon, Kelly Young, Moira Galbraith, Richard Ian Perry Apr 2018

Zooplankton Variability In The Northern Salish Sea Over The Past 3 Decades, And Relationships With Coho Salmon, Kelly Young, Moira Galbraith, Richard Ian Perry

Salish Sea Ecosystem Conference

The past 30 years have seen huge changes in the populations of Pacific salmon in the Salish Sea. These changes include very large reductions in the abundances of Chinook and Coho, and high variability of Fraser River Sockeye salmon populations. The Salish Sea Marine Survival Program is a Canada – U.S. collaborative multi-year research initiative established to investigate two main questions: what has driven the very strong declines in abundances of Coho and Chinook populations in the Salish Sea since the 1980s, and what determines the interannual variability of present populations. In this study we examine these two questions from …


Seasonal Dynamics Of Oceanographic Conditions, Phytoplankton, And Zooplankton In The Malaspina Strait, Strait Of Georgia, Svetlana Esenkulova, Karyn Suchy, Richard Ian Perry, Kelly Young, Maycira Costa, Ryan Flagg, Moira Galbraith, Isobel Pearsall Apr 2018

Seasonal Dynamics Of Oceanographic Conditions, Phytoplankton, And Zooplankton In The Malaspina Strait, Strait Of Georgia, Svetlana Esenkulova, Karyn Suchy, Richard Ian Perry, Kelly Young, Maycira Costa, Ryan Flagg, Moira Galbraith, Isobel Pearsall

Salish Sea Ecosystem Conference

Plankton dynamics in the Salish Sea may directly impact resident and migratory fish populations that are of major economic importance in the region. The Malaspina Strait in the northern Salish Sea is of particular interest as it is an important migration route for juvenile salmon. Here, we present data collected at three stations in the Malaspina Strait as part of the Citizen Science initiative of the Salish Sea Marine Survival Project. Sampling was conducted at bi-monthly (or higher) frequency from February to October, 2015 to 2017. Relationships between the regional hydrography, environmental parameters (temperature, salinity, dissolved oxygen, etc.), nutrient concentrations, …


The Effects Of Anti-Sea Lice Drugs And Pesticides On Marine Zooplankton, Jenna Keen Apr 2018

The Effects Of Anti-Sea Lice Drugs And Pesticides On Marine Zooplankton, Jenna Keen

Salish Sea Ecosystem Conference

The quality of near-shore coastal waters and estuaries is of great concern to North Americans, particularly as these ecosystems become increasingly threatened by pollution. An improved understanding of chemical impacts on near-shore ecosystems is essential to responsible stewardship of these coastal areas. In recent years, the aquaculture industry has become a major contributor to the Canadian economy, however, this industry’s use of chemicals, including those used in disinfectants, anti-fouling paints, and feed additives has resulted in the contamination of local net pen areas. Another complication of these net-pen areas is the abundance of sea lice on the fish, which the …
