An ocean of noise: how sonic pollution is hurting marine life

April 12, 2022 — We were whaling with cameras, joining a flotilla of a dozen other tourist boats from harbours all around the Salish Sea. It was one of my first trips to the area, in August 2001. The fuzz and beep of ship radios stitched a net over the water, a blurry facsimile of the sonic connections of the whales themselves. Every skipper heard the voices of the others, relayed by electromagnetic waves. The quarry could not escape. “Whales guaranteed” shouted the billboards on shore.

We motored on, weaving around island headlands. A sighting off the south-west shore of San Juan Island. Through binoculars: a dorsal fin scythed the water, then dipped. Another, with a spray of mist as the animal exhaled. Then, no sign. But the whales’ location was easy to spot. A dozen boats clustered, most slowly motoring west, away from the shore. We powered closer, slowing the engine until we were travelling without raising a wake and took our place on the outer edge of the gaggle of yachts and cruisers.

A sheet of marble skated just under the water’s surface. Oily smooth. A spill of black ink sheeting under the hazed bottle glass of the water’s surface. Praaf! Surfacing 15 metres ahead of the boat, the exhalation was plosive and rough.

The pod of about 10 animals came to the surface. Part of the L pod of orcas, our captain said, one of three pods that form the “southern residents” in the waters of the Salish Sea between Seattle and Vancouver, often seen hunting salmon around the San Juan Islands. Others – “transients” that ply coastal waters and “offshores” that feed mostly in the Pacific – also visit regularly. The L pod continued west, heading toward the Haro Strait. Our engines purred as the U-shaped arc of boats tracked the pod, leaving open water ahead of the whales.

We dropped a hydrophone over the boat’s gunwale, its cord feeding a small speaker in a plastic casing. Whale sounds! And engine noise, lots of engine noise. Clicks, like taps on a metal can, came in squalls. These sounds are the whales’ echolocating search beams. The whales use the echoes not only to see through the murky water, but to understand how soft, taut, fast or tremulous matter is around them.

Mixed with the staccato of the whales’ clicks were whistles and high squeaks, sounds that undulate, dart, inflect up and spiral down. These whistles are the sounds of whale conviviality, given most often when the animals are socialising at close range. When the pod is more widely spaced during searches for food, the whales whistle less and communicate with bursts of shorter sound pulses. These sonic bonds not only connect the members of each pod, but distinguish the pod from others.

Today, ocean waters are a tumult of engine noise, sonar and seismic blasts. Sediments from human activities on land cloud the water. Industrial chemicals befuddle the sense of smell of aquatic animals. We are severing the sensory links that gave the world its animal diversity. Whales cannot hear the echolocating pulses that locate their prey, breeding fish cannot find one another amid the noise and turbidity, and the social connections among crustaceans are weakened as their chemical messages and sonic thrums are lost in a haze of human pollution.

Feds say pesticide won’t destroy species

March 9, 2022 — The Fish and Wildlife Service has concluded that the pesticide malathion does not jeopardize threatened and endangered species or their habitat.

In a much-awaited study that’s drawing sharp criticism from environmentalists, the federal agency backed off its most recent draft conclusion that the registration of malathion for use was likely to threaten 78 species and destroy or adversely modify 23 critical habitats (Greenwire, April 21, 2021).

“The Biden administration has squandered a historic opportunity to rein in the dangerous use of one of the world’s worst neurotoxic pesticides,” Lori Ann Burd, environmental health director at the Center for Biological Diversity, said in a statement today.

Burd noted that NOAA Fisheries recently released its own updated biological opinion that determined malathion and two other organophosphate pesticides jeopardize endangered U.S. salmon, sturgeon and steelhead species, as well as Puget Sound orcas.

NOAA Biological Opinion Concludes Marine Finfish Aquaculture Has No Adverse Impact on Salmon, Orcas, and Other Native or Endangered Species in Puget Sound

March 1, 2022 — The following was released by the Northwest Aquaculture Alliance:

NOAA’s National Marine Fisheries Service has released a biological opinion regarding marine finfish aquaculture in Puget Sound, finding little to no negative impact on native species such as endangered salmon, Orcas, or their habitat.

The NOAA analysis was initiated in October of 2018 to analyze the effects of the United States Environmental Protection Agency’s (EPA) approval of the Washington Department of Ecology’s Sediment Management Standards regarding marine finfish rearing facilities.

In its analysis, NOAA found that EPA’s approval:

  • Is “not likely to jeopardize the continued existence” of Puget Sound (PS) and/or Georgia Basin (GB) species, including Chinook salmon, PS steelhead, Hood Canal summer-run chum, PS/GB yelloweye rockfish, or PS/GB bocaccio.
  • Is “not likely to result in the destruction or adverse modification of the designated critical habitats for any of the listed species.”

In response to this opinion, the Northwest Aquaculture Alliance (NWAA), which advocates for the sustainable production of aquatic foods in the Pacific region, is calling on regulators and policymakers to follow the science in making key decisions regarding marine aquaculture in Washington waters.

“After years of meticulous research and study, the scientists at NOAA have concluded, with full scientific certainty, that net-pen aquaculture in Puget Sound is safe for the environment and safe for the endangered species that live in these waters,” said Jim Parsons, NWAA President. Parsons is also CEO of Jamestown Seafood.

“This study, along with the recent unanimous Washington Supreme Court decision upholding Cooke Aquaculture Pacific’s permit to raise native steelhead in Puget Sound, finally puts to rest one of the biggest myths of all: that fish farming has a negative impact on endangered Chinook salmon and Orcas,” Parsons said.  “As aquatic farmers, we depend on a healthy ecosystem to grow a range of aquatic food products–from steelhead trout to black cod to oysters, clams, mussels, and sea vegetables—instead of importing these foods. Sustainable aquaculture not only produces the nutritious, affordable food our world needs, but it also benefits working families in our rural communities.”

Parsons added: “Given the current world situation, it’s time for Washington to lead the way in delivering fresh, locally produced, seafood to consumers throughout the Pacific Northwest and the United States. We encourage our leaders to rely on science rather than politics or claims made by certain anti-aquaculture activist groups in making key decisions about the future of aquatic farming and the Blue Economy in Washington.”

A court decision may help endangered orcas, but Alaskan fishermen are wary

November 8, 2021 — The southern resident killer whale population, three pods of orcas that ply the coastal waters between Monterey, California, and Vancouver Island, British Columbia, has dwindled to only 73 members. Scientists believe this endangered species, which relies almost exclusively on Chinook — or king — salmon, which are also in steep decline, is basically starving its way to extinction.

This past September, however, the U.S. District Court in Seattle seemed to offer the marine mammals a lifeline when it issued a preliminary decision that might make more Chinook available to orcas. Responding to a lawsuit filed by the Wild Fish Conservancy, the court found that the National Marine Fisheries Service (NMFS), the agency responsible for management of both fisheries and endangered marine species, had violated the Endangered Species Act when it determined that commercial harvest of Chinook off southeast Alaska would not jeopardize southern residents or endangered king salmon populations.

But while the court decision is expected to help orcas, it may be bad news for fishermen, as NMFS will likely need to rethink Chinook harvests.

Feds OK plan to cut salmon fishing when needed for Northwest orcas

October 13, 2021 — Federal officials have approved a plan that calls for cutting nontribal salmon fishing along the West Coast when the fish are needed to help the Northwest’s endangered killer whales.

National Oceanic and Atmospheric Administration Fisheries adopted the plan Sept. 14 as recommended by the Pacific Fishery Management Council. It calls for restricting commercial and recreational salmon fishing when Chinook salmon numbers are especially low.

It’s one of the the first times a federal agency has restricted hunting or fishing one species to benefit a predator that relies on it.

The southern resident killer whales — the endangered orcas that spend much of their time in the waters between Washington state and British Columbia — depend heavily on depleted runs of fatty Chinook. Recent research has affirmed how important Chinook are to the whales year round, as they cruise the outer coast, and not just when they forage in Washington’s inland waters in the summertime.

Navy steams ahead with sonar testing despite state opposition, orca impacts

October 4, 2021 — Over the objections of Washington state officials and orca advocates, the U.S. Navy is steaming ahead with a plan for seven more years of testing sonar and explosives in waters off the Northwest coast.

The Navy says the piercing noise from its tests and training activities could harm eight species of whales listed under the Endangered Species Act.

But Navy officials, backed up by the National Marine Fisheries Service, say the occasional, temporary disturbances won’t threaten the orcas’ or any other species’ survival.

“At this time the Navy intends to proceed over the objection of the State of Washington,” the Navy’s Record of Decision document, published Friday, states.

NMFS approves plan to restrict salmon fishing, protect orcas

September 17, 2021 — King salmon fishing could be cut back from Puget Sound to Monterey Bay if king salmon numbers fall too low to feed the 75 endangered Southern Resident orcas, under a plan approved Sept. 14 by NMFS.

Non-tribal fishing would be restricted when king salmon numbers appear heading toward that threshold — a key recommendation from a working group convened by the Pacific Fishery Management Council, including representatives from West Coast states, tribes, and NMFS.

In late 2020 the council adopted the work group’s suggestions, including limiting commercial and recreational fishing in certain places off California, Oregon, and Washington when estimated king salmon numbers north of Cape Falcon, Oregon, fall below a certain level of abundance.

That level would be set as the average of the seven lowest years of forecast king salmon abundance off the northern Oregon and Washington coasts, currently estimated at 966,000. In recent years salmon numbers held above that level, and 2007 was the last year when forecasts would have fallen below the threshold.

Endangered orcas at risk from U.S. Navy, activists warn

August 3, 2020 — In the Pacific Northwest, an endangered community of killer whales has been on the decline for years due to a variety of factors, all related to human activity. Now, advocacy groups are warning of another looming threat which could further weaken the killer whale population: the U.S. Navy.

The Southern Resident killer whales are a small, close knit community of animals — more accurately known as orcas, the largest species of dolphins — which live primarily along the coast of Oregon, Washington and British Columbia. When they were listed as endangered in 2005, there were 88 Southern Resident orcas — but now, due to declines in their favorite food, Chinook salmon, as well as other manmade threats like toxins, shipping traffic and warming waters due to climate change, their numbers have dwindled to 72.

That’s why a recent request from the U.S. Navy seeking authorization for 51 “takes” of killer whales in the region each year for the next seven years alarmed many environmental groups.

WASHINGTON: Gov. Jay Inslee’s orca-recovery agenda advancing, but billion-dollar funding yet to be seen

April 22, 2019 — Gov. Jay Inslee’s orca agenda is advancing in the Washington state Legislature, but with the budget yet to be decided how much of the governor’s billion-dollar-bold ambition will be accomplished is yet to be seen.

Budgets passed by the House and Senate so far contain no funding to continue the governor’s task force on orca recovery. There’s no agreement yet on funding the governor’s proposed panel to consider the effects of breaching the Lower Snake River dams. And revenue measures to help pay for everything, from increasing hatchery production to enforcement of habitat protections, have yet to be decided.

There also were policy disappointments for the governor, who got no takers for his request for legislation to put a temporary stop on whale watching of southern resident killer whales; no lawmaker would introduce the bill. A vessel noise-reduction package will take years to implement with rule making yet to be done, and because U.S. Coast Guard regulations include important exemptions, including for commercial shipping that makes most of the noise that can disrupt orcas as they hunt.

Feds Agree to Expand Habitat Protections for Northwest Orcas

April 16, 2019 — The federal government says that by October it will propose expanded habitat protections off Washington, Oregon and California for Pacific Northwest orcas.

The announcement comes in response to a lawsuit filed by the Arizona-based Center for Biological Diversity, which sued in 2018 to make officials move more quickly to protect the endangered orcas.

The whales spend their summers in the waters between Washington state and Canada, but about two-thirds of the year they migrate and forage for salmon off the West Coast. The conservation group said the National Marine Fisheries Service had been dragging its feet in designating “critical habitat” for the whales in those foraging and migration areas.
