Oil Spill Preparedness Planning: Filling Critical Species Data Gaps Using Habitat Suitability Modelling, Candice St. Germain, Jessica Finney, Cole Fields, Edward Gregr, Lucie Hannah, Sharon Jeffery
Salish Sea Ecosystem Conference
Under the World Class Tanker Safety System Initiative (WCTSS) a national framework was developed to identify marine biological organisms most vulnerable to ship-source oil spills. The Pacific regional application of this framework identified 27 highly vulnerable biological groups, with sea grasses, salt marsh grasses/succulents, sea otters, and baleen whales at the top of the list. A gap analysis during the Pacific regional application identified critical species data gaps that must now be filled to ensure effective response in marine oil spill emergencies. In the absence of robust species distribution and abundance data, habitat suitability models can be used to predict …
Biogeochemical Cycling Of Polybrominated Diphenyl Ethers (Pbdes) In The Strait Of Georgia, Yuanji Sun, Maria T. Maldonado, Roger Francois
Biogeochemical Cycling Of Polybrominated Diphenyl Ethers (Pbdes) In The Strait Of Georgia, Yuanji Sun, Maria T. Maldonado, Roger Francois
Salish Sea Ecosystem Conference
The temporal and spatial distribution of dissolved and particulate PBDEs seawater concentration has been monitored in the Strait of Georgia (SoG) since 2013. We aim to determine the sources, sinks and biogeochemical cycling of PBDE congeners in the water column in SoG. Particulate PBDEs concentrations show high temporal and spatial variability, indicating that the outfalls from the waste water treatment plants are major point sources. Changes in congener distributions in relation to total particulate PBDE concentrations suggest that the less brominated congeners desorb from sewage particles and add to the dissolved PBDEs pool more rapidly than the more brominated congeners. …
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, …
Dissolved Cu Concentrations In The Strait Of Georgia: Trends, Speciation, And Accumulation By Local Calanoid Copepods, Bertha Iselle Flores Ruiz, Jack Anthony, Lori-Jon C. Waugh, Cheng Kuang, Roger Francois, Maria T. Maldonado

Most research on the effects of copper (Cu) on marine ecosystems has focused on benthic organisms and Cu concentrations in the sediments. In contrast, little is known about the effects of dissolved copper (dCu) in pelagic food webs. In most marine waters, more than 99.9% of dCu is bound to organic ligands. These ligands diminish dCu toxicity to aquatic organisms by lowering the concentrations of inorganic dCu, the most bioavailable species of Cu. For the past year, we have studied seasonal trends of dCu concentrations in the Strait of Georgia and have measured and characterized its speciation in seawater. Measurements …
Dispersion And Removal Of Two Toxic Trace Metals (Ag And Cd) In The Strait Of Georgia, Cheng Kuang, Bertha Iselle Flores Ruiz, Samuel Stevens, Maria Maldonado, Roger Francois
Dispersion And Removal Of Two Toxic Trace Metals (Ag And Cd) In The Strait Of Georgia, Cheng Kuang, Bertha Iselle Flores Ruiz, Samuel Stevens, Maria Maldonado, Roger Francois
Salish Sea Ecosystem Conference
Two highly toxic trace metals, silver (Ag) and cadmium (Cd) have been monitored in the sediments and water column of the Strait of Georgia since 2014. With the advent of nanotechnology, silver nanoparticles are widely used in medical applications and consumer products, and inevitably being discharged into the environment. Cd is of particular concern in the coastal waters of B.C. due to its naturally high concentration in the incoming Pacific water and possible anthropogenic sources. The sediment profile of a core taken near the Iona Island wastewater treatment plant outfall showed rising levels of both Ag and Cd in the …
Harmful Algae In The Strait Of Georgia, Citizen Science Data, Svetlana Esenkulova, Isobel Pearsall
Harmful Algae In The Strait Of Georgia, Citizen Science Data, Svetlana Esenkulova, Isobel Pearsall
Salish Sea Ecosystem Conference
The Citizen Science Program was initiated by the Pacific Salmon Foundation, Fisheries and Oceans Canada, and Ocean Networks Canada in 2015. This Program was designed to achieve oceanographic monitoring of the Strait of Georgia on temporal and spatial scale that had never been done before. Samples and measurements were taken at approximately 80 sites on a bi-monthly (or higher) frequency from February to October, 2015 to 2017. This presentation will be focused on the spatial and temporal distribution of harmful algae based on the analysis of about 5000 phytoplankton samples. Preliminary results indicate that during the sampling period in the …
