Ocean Pollution 

The Northeast Pacific Ocean conjures images of tidal pools, migrating salmon, pods of killer whales and awe-inspiring grizzly bears. It also provides food, jobs and security to the people of the region, through fishing, trade and ecotourism. However, the diverse ecosystems of this coastal region face tremendous pressures, as both local and global stressors threaten their health. Threats include urban and industrial effluents, runoff from forestry and agriculture, oil and gas shipping and exploration, plastics and debris, and climate change. Understanding the nature and extent of these threats provides a basis for policies and practices to protect ocean health for future generations.

Program Launch

The Ocean Pollution Research Program was established in 2014 as a major new Vancouver Aquarium research initiative. This program is conducting international-caliber scientific research on priority topics in ocean pollution. Its focus is to determine the sources and consequences of ocean pollution, communicating results to stakeholders and the public, and to provide guidance on solutions in the form of best practices, consumer choices and policies.

Dr. Peter S. Ross, an internationally recognized scientist with over 25 years of experience in marine pollution research in government and academia, is serving as the Program’s founding director and senior scientist.

Dr. Marie Noel is the program’s new Research Manager, overseeing safe and effective laboratory and field operations.

Mrs. Anahita Etemadifar is a Research Analyst, focusing on the lab-based forensic analysis of microplastics in environmental samples.

Kelsey Delisle is the new PollutionTracker Coordinator, overseeing the collection, analysis and interpretation of contaminant data from sediments and mussels collected from over 50 stations along the British Columbia coast.

The Ocean Pollution Research Program has the support of graduate students, post-doctoral fellows and biologists working on individual projects, as well as university, government and private sector collaborators. A new laboratory with state-of-the-art equipment for measuring the impacts of ocean pollutants has been established to enable in-house research.

Key Program Components

  • Microplastics in the ocean
  • Marine mammals as sentinels of ocean pollution
  • Clean seafood for coastal aboriginal communities
  • PollutionTracker, a new coast-wide monitoring initiative
  • Oil spill science

The Ocean Pollution Research Program builds on established knowledge, provides critical research capacity to Western Canada, and establishes British Columbia as a leader in this vitally-important field.

Pollution tracker

The Ocean Pollution Research Program Will:

  • Measure the health of invertebrates, fish and marine mammals in a newly-established Ocean Pollution Research Laboratory using instruments that quantify hormones, enzymes, proteins, antibodies, gene expression and immune endpoints;

  • Measure the levels of contaminants including microplastics, pesticides, industrial chemicals, flame retardants, pharmaceuticals, hydrocarbons and metals in invertebrates, fish, marine mammals and their habitat;

  • Design and conduct research projects that broaden our concepts of ocean health, conservation science, and understanding of human impacts;

  • Establish a network of collaborators to leverage capacity through existing ocean science research platforms in Canada and internationally (e.g. ships, field stations and specialized laboratories);

  • Facilitate solutions through creative research, stakeholder engagement programs, and expert working groups; and

  • Provide science content to educators, conservation managers and policy makers.

The Ocean Pollution Research Program works actively with other programs within the Vancouver Aquarium family. For example, it collaborates with the Marine Mammal Research Program on studies of the health of killer whales, with the Howe Sound Research Group on applied, local studies in a ‘living laboratory’, and with the Aquarium’s veterinary department and Marine Mammal Rescue Centre on factors affecting marine mammal health.
