Houses burn as new volcanic eruption threatens Icelandic village
Houses caught fire after a new volcanic eruption sent smoke and lava spewing out near the Icelandic fishing port of Grindavik Sunday, just hours after villagers were evacuated to safety, authorities said. It was the North Atlantic nation’s fifth volcanic eruption in under three years. The most recent occurred just weeks ago on December 18 in the same region, southwest of the capital Reykjavik. “In a little village like this one, we’re like a family, we all know each other as family — it’s tragic seeing this,” local resident Sveinn Ari Gudjonsson told AFP. “It’s unreal, it’s like watching a film,” added the 55-year-old, who works in the fishing industry. 7 photos. more, >>click to read<< 15:48
New DFO northern cod assessment model shows stock out of critical zone
Fisheries and Oceans Canada has implemented a new assessment model for the 2J3KL northern cod stock, which reveals the stock has likely been out of the critical zone since 2016. The new model assesses the long-term productivity using tagging and landing data from the last 70 years. The old model used data beginning in 1983, but research scientist Paul Regular says the model has been expanded to pull on data from as far back as 1954. “A bunch of changes were accepted, and they helped us improve the understanding of the past trends in the stock, and also the relationship between adult cod and young cod,” Regular said Wednesday. >>click to read<< 19:11
Study: Marine heat waves do not affect fish populations
The lead author of the study, Assistant Professor in the Department of Oceanography at the University of California, Alexa L Fredston said she was surprised by these results. She added: “We know that fish communities faced long-term ocean warming by moving towards the poles, which can change the biomass and composition of fish in a given location. So I expected similar result, i.e. more fish species in “Warmer waters and fewer fish in colder waters after these marine heatwaves.” The American, Canadian and European researchers who conducted the study analyzed more than 82,000 bottom trawl fish catches collected as part of scientific expeditions in the North Atlantic and Northeast Pacific Oceans. >>click to read<< 13:01
After six years of tracking mackerel in the North Atlantic, scientists have uncovered a few fishy secrets.
Do mackerel outcompete herring? And does the fact that mackerel are so widespread in the Nordics mean that their populations are booming? Researchers have spent six years trying to answer these and other questions, and the answers are now beginning to come clear. Their efforts are motivated by more than just academic curiosity. Researchers’ recommendations help shape international quotas that help protect fish stocks, which in the case of mackerel have had a rocky history. >click to read<13:14
