Geomagnetic Disruptions from Mining Could Disrupt Salmon’s Ability to Return to Bristol Bay
This is Alaska Fish Radio. I’m Laine Welch –
Is it a coincidence that one of the world’s largest mineral deposits is near the largest sockeye salmon spawning grounds at Bristol Bay? And if a massive mine like Pebble removed those deep deposits that create the world’s magnetic field – could it disrupt salmon’s ability to find their way home?
A study underway aims to find out.
“It's not even been 10 years since we've discovered that salmon are using Earth's magnetic field as a way to...
