Climate change forces 3rd gen fisherman to rethink this year
Every June, fisherman Scott Hawkins and his small crew set sail from a marina in San Diego and travel hundreds of miles, scouring the water, hoping for a good catch of albacore tuna. It can take hours or days to stumble upon a school of them. But when they do, everyone springs into action at once. The men grab fishing poles taller than they are, stand in a row on the edge of the boat and cast their lines into the water. Every few seconds, one of them pulls up a fat, two-foot-long albacore tuna and hoists it over his shoulder onto the pile. Every thud is another one landing atop the dozens already flapping on deck. They do this 17 hour per day for five months. “It’s the exact same that my grandfather did in the 50s,” Hawkins says. But this June, the boat isn’t leaving the marina. more, >>CLICK TO READ<< 15:16
Warming Waters Heat Summer’s Feast Well Before It Gets to the Kitchen
An ever-warming planet is playing havoc with the intricately interconnected web of marine life. Just as climate has long stressed human populations and driven migration, marine populations are stressed and in search of survivable climates too. In New England, scientists and lobstermen alike are studying and living the impacts. Tim Alley has been lobstering in Maine’s coastal waters for 40 years. “There’s been a trend in recent years related to temperatures,” he says. Alley is steeped in the traditions of his home state’s biggest industry and recently dusted off a short film from 1972 in which he starred at age 12, “Alone in My Lobster Boat,” filmed in South Bristol and New Harbor, Maine. Like most lobstermen, he would call himself an environmentalist: they live on the water, they live from the water, they thrive on the water. But they reject the notion that a species – the right whale – is failing because of them. Over 40 years, he says, he has seen exactly one right whale. Photos, Video, more, >>CLICK TO READ<< 14:50
Ocean temperatures off N.S. dip after record breaking year, have moved back to normal
Following a season of record-breaking surface temperatures last year, ocean temperatures in the waters around Nova Scotia have moved back to normal this summer, says the Department of Fisheries and Oceans.,,, In 2018, DFO found winter sea surface temperatures from the Scotian Shelf to the Bay of Fundy were above normal. There were also record-breaking temperatures in August and September. However, DFO’s spring survey conducted in April 2019 differed from last year’s results. “First, the surface was really cold because we had a really cold winter. It takes time for the ocean to heat up,” Hebert said. “The deeper water seemed to be back to the normal temperature.” >click to read< 09:44
Warming trend continues in waters off Atlantic Canada
Warmer ocean temperatures off Atlantic Canada continued in 2016, maintaining a trend that started earlier this decade, according to survey results from Canada’s Department of Fisheries and Oceans. On the Scotian Shelf off Nova Scotia, temperatures last year were as high as three degrees above the 30-year average used to establish climatic norms. “It’s not quite the same [record] level of 2012, but it’s getting close to it,” said Dave Hebert, a research scientist with DFO. He added that 2016 was probably the second warmest year on record. Scientists have struggled to explain what is causing the most intriguing aspect of the recent trend: the warming of ocean bottom water, which is not influenced by surface weather events. Hebert said the latest theory is based on model results that see the Gulf Stream moving northward and intersecting with the tail of the Grand Banks. “That is stopping the cold Labrador Sea water from coming around the tail of the Grand Banks,” he said. “That’s where we normally get the cold water that refreshes the [Scotian] Shelf. That hasn’t been happening. Read the story here 16:48
Are you a big-picture person, or do you focus on the details? Two Takes on Climate Change in the Ocean

New Ocean Forecast Could Help Predict Fish Habitat Six Months in Advance
Being able to predict future phytoplankton blooms, ocean temperatures and low-oxygen events could help fisheries managers,” said Samantha Siedlecki, a research scientist at the UW-based Joint Institute for the Study of the Atmosphere and Ocean. more@sciencedaily 10:37
Lobster fishermen are worried about another price-depressing glut because ocean temperatures are higher than normal.
