Comox Valley Nature webinar to discuss effect of climate change on marine life

A trifecta of extreme weather events took turns battering British Columbia this year: wildfires, floods and a summer heatwave that killed off billions of sea life.

A leading expert at the Institute for Oceans and Fisheries and the Department of Zoology at the University of British Columbia will discuss the effects of climate change in an online lecture for Comox Valley Nature this Sunday.

Dr. Chris Harley will present “Well that stunk: mass die-offs of BC seashore life during the 2021 heatwave” in a live webinar from 7:00 pm to 9:00 pm this Sunday, Nov. 21.

In late June, western North America experienced an unprecedented heatwave. A new Canadian all-time high-temperature record was set and hundreds of people died.

Along the coast of BC, the high temperatures coincided with very low tides, and that combination was lethal for billions of barnacles, mussels, sea stars, and other sea creatures that live in the intertidal zone. Such intense heat waves, once a 1-in-1000 year occurrence, are expected to become more common and more severe due to climate change.

Harley’s lecture will provide an overview of how climate change has already impacted seashore life in British Columbia. He will then describe the impacts of the 2021 heatwave – it’s geographic extent, the species affected, and the ongoing ecological implications for the northern Strait of Georgia and beyond.

Harley has been studying coastal marine ecosystems along the west coast and around the world for over 25 years. He and his students at UBC are interested in how marine ecosystems are changing and why. They study the ecological impacts of gradual warming, sudden heat waves, ocean acidification, and changes in salinity.

They are especially interested in how biodiversity is changing as a result, and how certain key species can speed up or slow down ecological change driven by human activities.

Comox Valley Nature is a non-profit society affiliated with BC Nature, consisting only of unpaid volunteers. Founded in 1966, it is one of the oldest environmental societies on the North Island. You can register for the webinar here.

Do you want to learn about the threats facing whales in our waters and what local citizens can do to help to protect them? Comox Valley Nature has invited Sarah Patton to present an illustrated talk, The Whales in Our Waters, at 2:00 pm Thursday, May 30 in the Denman Island Community Hall, 1196 Northwest Road, Denman Island. 

Patton is a Research Biologist with Ocean Wise’s Marine Mammal Research Program, and coordinator of its Southern Vancouver Island Cetacean Research Initiative (SVICRI).

Ocean Wise’s Marine Mammal Research Program has conducted conservation-oriented research on killer whales, belugas and other marine mammals since the mid-1980s. The program focuses on long-term studies of marine mammal populations in BC, and works across multiple science-based platforms to understand and mitigate the threats they face.

Patton’s experience in her field includes nearly 20 years working on marine research and conservation within governments in Canada, Australia and the USA, with several Canadian and international non-profits, and within academia. She holds a master’s degree in marine conservation biology from James Cook University in Australia, which she took as a Rotary International Academic Ambassador representing Eastern Canada. She also earned an undergraduate degree in marine biology from Dalhousie University, and a diploma in adult education.

In her spare time, Sarah is an avid outdoors woman and naturalist, and an active member of Maritime Search and Rescue Station #35 in Victoria.

Comox Valley Nature is a non-profit society affiliated with BC Nature, consisting only of unpaid volunteers. CVN fulfills its educational mandate by hosting monthly lectures, organizing free weekly guided hikes for members, and a free monthly walk open to the public. Comox Valley Nature also supports specialized groups (birding, botany, marine and shoreline, conservation, Garry Oak restoration, wetland restoration, photography and a Young Naturalists Club) which have separate monthly activities. Membership in BC Nature and Comox Valley Nature is $30 per adult or for a family.

Founded in 1966, it is one of the oldest environmental societies on the North Island. Meetings and lectures of the Comox Valley Naturalists Society are held on the third Sunday of most months at the Florence Filberg Centre in Courtenay. Meetings and guided walks are open to the public, including children and youth.

This lecture is free, although a $4 contribution from non-members would be appreciated. New memberships are always welcomed.

Anyone interested in this lecture or participating in CVNS activities can contact CVN at their website.  

 

 

 

 

 

KILLER WHALES
AT A GLANCE

Survival has become uncertain for the southern resident killer whale. For years, pressures on these awe-inspiring whales — icons of the Pacific coast, culturally significant to First Nations people and beloved by tourists — have been increasing. Today, only 74 wild southern resident killer whales remain, and the next few years will determine if the group can rebuild or go functionally extinct.

Scientific name: Orcinus orca
Status: Endangered
Adult Weight: Up to five tonnes
Diet: Chinook salmon
Population: 74 individuals
Location: Southeastern Alaska to central California. In spring and summer, they can be found off the coast of British Columbia in the Salish Sea.
