We know noise is a problem. We know it even affects ecosystem services. How about we decrease the noise? How about that? Instead of condoning naval sonar and oil and gas drilling operations?

The Norwegian government has given the go-ahead to scientists to
conduct an unprecedented experiment on migrating juvenile Minke
whales which involves trapping and subjecting them to painful noise
pollution.
If the experiment proceeds, at least a dozen of these gentle giants
will be captured and experimented on over the next two migration
seasons.
The decision has drawn sharp criticism from 50 of the world’s
leading whale experts and animal rights groups — including the
Animal Welfare Institute (AWI), NOAH — Norway’s largest NGO for
animals — and Whale and Dolphin Conservation, who have penned an
open letter to Norway’s prime minister urging the government to stop
these “cruel and dangerous experiments” from moving forward.
The Norwegian authorities claim the project, which received funding
from the US National Oceanic and Atmospheric Administration (NOAA)
and the U.S. Navy, is necessary to gain a better understanding of
how man-made noises — particularly naval sonar and oil and gas
drilling operations — affect whales’ hearing.
Researchers from Norway’s Defense Research Establishment (FFI) will
capture the whales one at a time in a mile-long dragnet. Once
inside, the unsuspecting juveniles will be funneled into a small
aquaculture cage — or fish farm — where they will be held in place
by rafts as sensors are planted under their skin. The scientists
will use the sensors to record the animal’s brain responses as they
are bombarded with varying levels of noise.
Petter Kvadsheim, chief scientist at FFI, acknowledged that the
planned procedures would harm the animals.
Officials at Norway’s Food Safety Authority (NFSA), which approved
the plan, acknowledged that the experiments were likely to cause the
whales “moderately severe” stress.” It went on to explain that some
of the whales could experience “short-term moderate pain, suffering
or distress,” while others might see “long-lasting mild pain,
suffering or distress.”
Opponents say this word salad is “an understatement.”
“This process risks causing the whale considerable stress leading to
panic, creating a dangerous situation for both whales and humans,”
they argue, adding that the capture-and-detain process amounts to
needless torture and “has significant potential for causing injury
and stress, potentially resulting in capture myopathy”– a condition
in which extreme exertion, struggle, or stress causes severe muscle
damage in the animal.
The results can be fatal.
“If a minke whale, even a juvenile, were to respond with great
force, it also could be extremely dangerous for the human
researchers,” said Susan Millward, director of AWI’s marine program.
“It is simply not worth taking a chance, particularly when existing
research already tells us how baleen whales are affected by ocean
noise.”
Instead, efforts should be made to develop quieter technologies,
said Lindy Weilgart, a whale communication and underwater noise
expert and signatory of the letter.
“We know noise is a problem. We know it even affects ecosystem
services,” Weilgart said. “How about we decrease the noise? How
about that?”
