Local Scientists Show Link Between Ocean Pollution And Illness

December 8, 2020 — A new study from Boston College and the Woods Hole Oceanographic Institution draws some jarring conclusions on the link between ocean pollution and human health. Lead researcher Dr. Philip Landrigan discussed the study with GBH All Things Considered Host Arun Rath. This transcript has been edited for clarity.

Arun Rath: I think people probably aren’t surprised to hear that our oceans are polluted. But how polluted are they? And was this a surprise?

Dr. Philip Landrigan: Yeah, I agree. It’s not news that the oceans are polluted. But what we learned through this two-year study that we took in collaboration with the government of Monaco is that ocean pollution is much more extensive than previously realized, and also that it has many more effects — direct effects and indirect effects — on human health than we had previously understood. I think those are the two big messages here.

Rath: We want to talk about the effects in detail. First though, do we have a clear understanding of the various sources of the pollution that is in the oceans?

Landrigan: Mostly. Not entirely, but mostly. So to run down the numbers, mercury is one of the big pollutants in the ocean. Coal combustion is the major source of that mercury. All coal contains a certain amount of mercury, and when you burn thousands of tons of coal, the mercury vaporizes, it goes up into the atmosphere, and it comes down into the oceans. In the ocean, it accumulates in fish, especially in predator species like tuna, like striped bass, like bluefish, like swordfish, and that’s how humans can be exposed. If a pregnant mom eats fish that’s contaminated with mercury that originated in a coal-fired power plant, that mercury goes into her body, goes through to her baby, and it can cause brain damage in the baby, loss of I.Q., increased risk of attention deficit disorder, increased risk of autism spectrum disorder.

Long-Running Plankton Survey to Resume in the Gulf of Maine

November 10, 2020 — The following was released by NOAA Fisheries:

A new agreement between NOAA’s Northeast Fisheries Science Center, the Marine Biological Association in Plymouth, England and the Woods Hole Oceanographic Institution will allow a plankton survey to resume. The survey was originally conducted across the Gulf of Maine from 1961 to 2017.

NOAA Fisheries is providing funding for the survey through the NOAA Cooperative Institute for the North Atlantic Region, hosted by the Woods Hole Oceanographic Institution. The Marine Biological Association manages merchant vessel-based plankton surveys around the world. The association will run and maintain the resumed Gulf of Maine survey through 2024 under this agreement.

“Continuing a long-term time series like the Continuous Plankton Recorder Survey is essential to understanding the impact of climate change to marine ecosystems,” said Chris Melrose, a research oceanographer at the Northeast Fisheries Science Center’s laboratory in Narragansett, Rhode Island and NOAA representative on the agreement.

“Many marine species are shifting their distributions as ocean waters warm,” explained Melrose. “Because plankton are an important food source for many species, including the endangered North Atlantic right whale, knowing about changes in the plankton helps us to understand other changes we see in the ecosystem.”

Long-running plankton survey to resume this winter

October 28, 2020 — Scientists this winter will revive a long-running survey of plankton in the Gulf of Maine. Plankton, drifting microscopic sea organisms, are food for endangered North American right whales and other marine species.

The Gulf of Maine plankton survey was originally performed from 1961–2017. It is returning under a new agreement between the National Oceanic and Atmospheric Administration’s (NOAA) Northeast Fisheries Science Center, the Marine Biological Association in Plymouth, England, and the Massachusetts-based Woods Hole Oceanographic Institution.

“Many marine species are shifting their distributions as ocean waters warm,” said Chris Melrose, a research oceanographer at the Northeast Fisheries Science Center’s laboratory in Narragansett, R.I. “Because plankton are an important food source for many species, including the endangered North Atlantic right whale, knowing about changes in the plankton helps us to understand other changes we see in the ecosystem.”

Melrose, who is NOAA representative on the agreement, said continuing the survey “is essential to understanding the impact of climate change to marine ecosystems.”

Heat waves on Cape Cod may be tied to slowing ocean current

October 19, 2020 — We really baked this summer, with the Northeast and the East Coast experiencing intense heat waves.

In August alone, the Blue Hill Observatory in Milton recorded six days with temperatures over 90 degrees, four more than the average for the month. July had five days with temperatures over 90, two more than the monthly average.

While we often seek relief in the ocean, marine heat waves also occur, and those can adversely affect the creatures and plants that live there and have no refuge except deeper, colder water, if they can find it. Marine heat waves can be deadly: Researchers say “The Blob,” a large mass of warm water that extended down nearly 700 feet along 1,800 miles of North Pacific coastline, may have killed off over 62,000 common murre birds.

While most might expect that air temperatures may be driving those higher water temperatures, oceanic currents play a major role.

The Atlantic Ocean right off our doorstep is one of the fastest-warming ocean bodies on the planet, and some researchers say that may be due to a slowdown of what is known as the Atlantic conveyor belt, a massive offshore current that transports cold water from the Arctic south to the equator and returns warm water to the north and to Europe.
