The Gulf Of Maine’s Temperature Was ‘Normal’ This Year — Which Is The New Cool

September 19, 2019 — It’s often reported that the Gulf of Maine’s waters are warming faster than 99 percent of the largest saltwater bodies on the planet. But scientists will tell you the trend can be volatile. This year, for instance, surface water temperatures in the Gulf have been their coolest since 2008. That may be providing some relief for some of the Gulf’s historic species, but ongoing climate change means that long-term prospects are still uncertain.

Lobsterman Seth Dube fishes 400 traps from his boat, the Alison Nicole, out of Camp Ellis in Saco.

“Off and on most of my life, and my father did it and my grandfather and now me, hopefully my boy,” Dube says.

This has been a good decade for Dube and the rest of Maine’s lobster fleet, with record catches most years since 2010. But this year, the beginning of the big summer harvest – when lobsters molt, shedding their old hard shells to reveal new, soft shells – was slow. Lobstermen and some scientists associate that with cooler water temperatures earlier this year.

Study Looks at Vulnerability of Eastern Bering Sea Fish, Crab, and Salmon Stocks to Climate Change

September 19, 2019 — The following was released by NOAA Fisheries:

NOAA scientists and partners have released a Climate Vulnerability Assessment for groundfish, crabs, and salmon in the Eastern Bering Sea. They looked at the potential impacts of changing climate, ocean temperatures, and other environmental conditions on 36 groundfish, crab and salmon stocks. Of these, four rockfish stocks, flathead sole and Tanner crab were determined to be the most vulnerable. Several other fish stocks were seen as potentially more resilient. This is because they may be able to move to areas with more favorable environmental conditions, such as more food and optimum water temperatures for growth and survival.

“Alaska fisheries are really important—they contributed 58% of U.S. landings and 29% of U.S. ex-vessel value in 2016, with the majority of Alaska landings and value obtained from the Eastern Bering Sea shelf,” said Robert Foy, director, Alaska Fisheries Science Center. “In the past few years water temperatures have been much warmer than average making the need for studies like this all the more imperative. Our science both in the field and in the lab is critical to monitor ecosystem changes and provide short-term and long-term forecasts to help commercial, recreational and subsistence communities anticipate and respond to changes that impact their way of life.”

Thirty-four scientists assisted with this stock analysis. They considered the likelihood of exposure to climate change, and the sensitivity and adaptability if exposed.

Researchers used existing information on climate and ocean conditions, species distributions, and species growth and development. They estimated each stock’s overall vulnerability to climate-related changes in the region.

Is ‘The Blob’ back? New marine heat wave threatens Pacific

September 18, 2019 — In the fall of 2014, marine ecologist Jennifer Fisher was stunned when jellyfish and tiny crustaceans typically found in warmer waters filled her nets off the coast of Oregon. The odd catch was just one sign of the arrival of a vast patch of warm water that came to be known as “The Blob”—a massive marine heat wave that lasted 3 years and dramatically disrupted ecosystems and fisheries along North America’s Pacific coast.

Now, with oceanographers warning that a new Blob could be forming in the Pacific Ocean, Fisher is again preparing for strange encounters when she heads out on a research cruise later this month. “This is a very similar situation,” says Fisher, who works at Oregon State University’s Hatfield Marine Science Center in Newport.

This time, however, Fisher and other scientists say they won’t be taken by surprise. They are preparing to more quickly share data on heat wave impacts with each other and with managers who may have to impose new catch limits to protect valuable fisheries. When The Blob arrived 5 years ago, “we didn’t realize the impact” it would have, recalls Toby Garfield, a physical oceanographer with the National Oceanic and Atmospheric Administration’s (NOAA’s) Southwest Fisheries Science Center in San Diego, California. “We’re going to stay ahead of this one.”

Scientists See A Hotter, Wetter, Less Snowy Future For Maine

September 17, 2019 — All this week, Maine Public – and more than 250 other news outlets all around the world – are reporting stories on climate change as part of the  “Covering Climate Now” project. In Maine, scientists say that climate change means hot summers, warm winters, more rain, and less snow, along with a warming gulf of Maine, and that will affect the state’s fisheries, its  economy and traditional ways of life.

Professor Ivan Fernandez of the Climate Change Institute at the University of Maine is one of the authors of the report, “Maine’s Climate Future.”  He told Maine Public’s Nora Flaherty that since the findings came out out in 2015, there have been many big changes in the state and globally, including an acceleration in the pace of change.

FERNANDEZ: What we’ve seen in the last five years is, obviously, a continuation – most of the time, evidence of an acceleration of many of the trends for climate change. We’ve also, obviously, lived through a few years where we have hurricanes and fires, and where we’re witnessing the loss of communities and island nations due to these sorts of climate related disasters. And so the I think the public awareness and the mounting evidence of these extreme events has picked up the pace in the last few years.

How Long Before These Salmon Are Gone? ‘Maybe 20 Years’

September 17, 2019 — The Middle Fork of the Salmon River, one of the wildest rivers in the contiguous United States, is prime fish habitat. Cold, clear waters from melting snow tumble out of the Salmon River Mountains and into the boulder-strewn river, which is federally protected.

As Bering Sea ice melts, Alaskans, scientists and Seattle’s fishing fleet witness changes ‘on a massive scale’

September 16, 2019 — Derek Akeya hopes for calm waters and a lucrative catch when fishing from a skiff in the Bering Sea that surrounds his island village.

But on this windy late summer day, waves toss about the boat as Akeya stands in the bow, straining to pull up a line of herring-baited hooks from the rocky bottom.

Instead of bringing aboard halibut – worth more than $5 a pound back on shore – this string of gear yields four large but far less valuable Pacific cod, voracious bottom feeders whose numbers in recent years have exploded in these northern reaches.

“There’s a lot more of them now, and it’s more than a little bit irritating,” Akeya says.

The cod have surged here from the south amid climatic changes unfolding with stunning speed.

For two years, the Bering Sea has been largely without winter ice, a development scientists modeling the warming impacts of greenhouse-gas pollution from fossil fuels once forecast would not occur until 2050.

MAINE: Wells National Estuarine Research Reserve gets grant for lobster research

September 13, 2019 — The Wells National Estuarine Research Reserve will receive about $250,000 over two years to study how warming coastal waters are affecting lobsters in the Gulf of Maine, the National Sea Grant Office has announced.

The Gulf of Maine is warming faster than most waters around the world.

Since lobsters thrive in cold water, this warming trend has raised concerns about the future of the Gulf’s lobster fishery. Southern New England has already seen dramatic declines in lobster counts and the fishery there is in jeopardy.

“Lobsters prefer cold water and will move to deeper, offshore areas to find it,” said Jason Goldstein, research director at the Wells National Estuarine Research Reserve. “We plan to discover how the inshore and offshore movements of female lobsters are affected by warming waters, and whether their young can settle and grow in shallow nursery habitats as coastal waters become warmer.”

Dangerous new hot zones are spreading around the world

September 12, 2019 — The day the yellow clams turned black is seared in Ramón Agüero’s memory.

It was the summer of 1994. A few days earlier, he had collected a generous haul, 20 buckets of the thin-shelled, cold-water clams, which burrow a foot deep into the sand along a 13-mile stretch of beach near Barra del Chuy, just south of the Brazilian border. Agüero had been digging up these clams since childhood, a livelihood passed on for generations along these shores.

But on this day, Agüero returned to find a disastrous sight: the beach covered in dead clams.

“Kilometer after kilometer, as far as our eyes could see. All of them dead, rotten, opened up,” remembered Agüero, now 70. “They were all black, and had a fetid odor.”

He wept at the sight.

The clam die-off was an alarming marker of a new climate era, an early sign of this coastline’s transformation. Scientists now suspect the event was linked to a gigantic blob of warm water extending from the Uruguayan coast far into the South Atlantic, a blob that has only gotten warmer in the years since.

West Coast marine life endangered by ‘blob’ heatwave

September 12, 2019 — A “blob” of warm water in the Pacific Ocean could disrupt the marine ecosystem off the coast of California, similar to an event that occurred five years ago, according to the San Francisco Chronicle.

The patch, designated the Northeast Pacific Marine Heatwave of 2019 and also referred to as a “blob,” is the second-biggest such mass in four decades and, according to experts, is on a similar path to that of one that, from 2014 to 2016, caused toxic algae blooms and killed sea life ranging from sea lions to salmon en masse.

“I am surprised to see something like this develop again so soon after what looked like the end of the marine heatwave in 2016,” Nate Mantua, head of the Landscape Ecology Team at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center in Santa Cruz, Calif., told the newspaper.
