An unusually dense flow of melting ice from the Arctic trapped several boats off Newfoundland during the first half of June, bringing the Maritime Province’s fishing season to a halt.
The Canadian Coast Guard says the ice has been so bad that its icebreaker Amundsen has been unable to free the trapped vessels.
The Coast Guard has instead been forced to rescue several crew members aboard the trapped ships by helicopter.
The snow crab season has been open for weeks, but most fishermen have been stuck ashore waiting for hazardous sea ice to pass.
Huge icebergs, some so massive they dwarf nearby buildings, are drifting along the coasts of Newfoundland and Labrador in Canada, creating an awe-inspiring sight for locals and tourists alike.
Antarctic icebergs have surprise role in slowing warming
The biggest icebergs breaking off Antarctica unexpectedly help to slow global warming as they melt away into the chill Southern Ocean, scientists said on Monday.
The rare Manhattan-sized icebergs, which may become more frequent in coming decades because of climate change, release a vast trail of iron and other nutrients that act as fertilisers for algae and other tiny plant-like organisms in the ocean.
These extract carbon dioxide from the atmosphere as they grow, a natural ally for human efforts to limit the pace of climate change blamed on man-made greenhouse gas emissions.
Ocean blooms in the wake of giant icebergs off Antarctica absorbed 10 to 40 million tonnes of carbon a year, the study estimated, roughly equivalent to annual man-made greenhouse gas emissions of countries such as Sweden or New Zealand.
The scientists studied satellite images of 17 giant icebergs off Antarctica from 2003-2013 and found that algae could turn the water greener for hundreds of kms (miles) around the icebergs, with nutrients spread by winds and currents.
There are typically 30 giant icebergs floating off Antarctica at any one time – they can linger for years. The study said the giant icebergs had an outsized impact in promoting ocean fertilization when compared with small icebergs.
