West Coast toxic hot spots threaten endangered salmon and killer whales

Editor’s note: Though Cortes Island is not mentioned in the following report, it is on the embedded map of metal hotspots. We appear to be either bordering on, or close to, the areas for cadmium (Cd), nickel (Ni) copper (Cu) and lead (Pb).

Newly identified toxic metal hot spots on the West Coast further threaten endangered killer whales and their key food source, a recent study shows.

Canada under pressure to ban deep-sea mining as global ocean summit starts in Vancouver

National Observer, Local Journalism Initiative Reporter

Canada is under increasing pressure to declare a moratorium on seabed mining just as federal leaders are set to host an international marine conservation summit. 

More than 700 international scientists and a multitude of environmental organizations are calling on Canada to ban the search for deep-sea minerals in its own waters and show global leadership by joining a chorus of countries, such as France, Germany, Chile and Pacific Island nations, in calling for a mining ban in shared international waters. The country will host the fifth International Marine Protected Area Congress (IMPAC5) starting Friday in Vancouver.

Ocean Acidification poses a top climate change danger on B.C. coast

National Observer, Local Journalism Initiative Reporter

Lurking in B.C.’s ocean is a lesser-known climate risk experts say has the potential to cause significant harm to the marine ecosystem and the economies of coastal communities.

Now scientists and stakeholders are developing an action plan to deal with the dual dangers of ocean acidification and hypoxia — or dangerously low oxygen levels — in the marine environment.

Climate change could spark international fish fights

National Observer, Local Journalism Initiative Reporter

Tensions between countries are likely to rise with the global temperature as valuable fish stocks fleeing warmer waters cross into different national boundaries, a new study suggests.

The climate crisis will push 45 per cent of the world’s shared fish stocks away from historic habitat ranges and migration routes by 2100, posing a challenge for international co-operation, said senior author William Cheung.

A type of Orca: the big game hunter of the sea

National Observer, Local Journalism Initiative Reporter

There’s a type of killer whale that prowls deeper waters and specializes in hunting big game, research by a B.C. scientist suggests.

West Coast residents are familiar with the well-known and iconic chinook salmon-eating endangered southern resident killer whales in the Salish Sea, and the more numerous Bigg’s killer whales, or transient orcas, that ply the shallower waters of B.C.’s coast and inlets in search of seals and other sea mammals.

But evidence indicates there’s a newly identified type of orca — outer coast killer whales — that are a distinct subgroup of transient whales, and which frequent the ocean depths along the continental shelf off the coast of central California and Oregon, said lead author Josh McInnes, a scientist with the Marine Mammal Research Unit at the University of British Columbia.
