Helping Scientists Protect Beluga Whales with Deep Learning

March 11, 2020 — In the U.S., there are five populations of beluga whales, all in Alaska. Of those five, the Cook Inlet population is the smallest and has declined by about seventy-five percent since 1979. Subsistence hunting contributed to this initial population drop, but this practice was regulated starting in 1999, with the last hunt in 2005. Still, the beluga whale population in Cook Inlet has yet to recover. This population was listed as an endangered species in 2008, with hopes that the population would begin to recover in the near future, but more than a decade later they continue to decline, with a current population estimate of 328 whales.

Like other toothed whales, beluga whales rely highly on sound. They produce acoustic signals to find prey and to communicate; consequently, scientists can use acoustic recordings to study beluga populations and behavior. In 2008, the NOAA (National Oceanographic and Atmospheric Administration) Alaska Fisheries Science Center, in partnership with the Alaska Department of Fish and Game, put together an acoustic research program to continuously monitor beluga whale habitat. This program has two main objectives: (1) studying beluga whale behavior and population size, and (2) understanding the extent to which human-generated noise is disrupting beluga populations.

In the past, with raw audio recordings collected by underwater moorings, NOAA scientists used a very basic detector — based on energy levels in certain frequencies — to detect acoustic signals from beluga whales. This detector was tuned toward high recall, i.e., it was tuned to make sure that it didn’t miss any beluga sounds, but consequently allowed many sounds to pass through that were false positives, i.e. uninteresting background noise. Consequently, manual validation was required for each of those detections. This validation process is very time-consuming and labor-intensive, which limits the number of sensors that the team can deploy, and also limits the speed with which the team can provide answers to critical conservation questions.

Are You Prepared: Coronavirus and the Alaska Economy

March 9, 2020 — Alaska’s major economic sectors are trying to find the best way to monitor and respond to the impact of the global spread of COVID-19, the novel coronavirus first documented in Wuhan, China, in December.

While China is a significant trade partner with Alaska, regardless of whether the virus shows up in Alaska, it could disrupt the state’s most significant financial drivers. With billions of dollars at stake, Alaska’s fishing, tourism, and oil and gas industries are in an awkward position between knowns and unknowns as they prep for how the virus will impact their businesses.

The Ted Stevens Anchorage International Airport is staying ready with round-the-clock mopping, wiping, and scrubbing.

“Our materials and our methods that we use here are designed to stop the spread of communicable disease in the airport. Whether it’s coronavirus or influenza or rotavirus or norovirus — all of those — we are always trying to keep the airport clean and safe,” airport manager Jim Szczesniak told KTUU.

The cleaning work is an investment in keeping goods and people moving through the airport, a global hub. Eighty percent of all air cargo from Asia to North America stops at the airport, and just under six million people pass through its terminals each year, many over the summer.

Vacationers bring about $4.5 billion into Alaska each year.

Among them: 1.4 million cruise ship passengers.

Pebble pulse: Bristol Bay leaders testify in federal court, say EPA went rogue

March 4, 2020 — Bristol Bay fishermen, tribal leaders and fisheries advocates once again offered their testimony on the value of protections for the world’s most productive sockeye salmon habitat.

On Monday, March 2, members of the Bristol Bay Defense Alliance testified in federal district court in support of a lawsuit the group filed against the Environmental Protection Agency in October.

The suit asserts the EPA’s withdrawal of proposed Clean Water Act protections was arbitrary and unlawful, and runs counter to the scientific and public record. The plaintiffs now await a ruling from Judge Sharon Gleason on whether the suit will move forward.

“Although we are now waiting for the judge’s ruling in this case, our primary goal is unchanged: protecting and promoting the Bristol Bay fishery,” said Andy Wink, executive director of the Bristol Bay Regional Seafood Development Association. “The science still supports 404 protections in Bristol Bay, and we will continue working to secure them.”

In 2010, six Bristol Bay Tribes requested the protections and soon were supported in the effort by commercial and sport fishing groups.

The China problem: Coronavirus creates a bottleneck for Alaska seafood

March 3, 2020 — Seafood coming from and going to China is piling up in freezer vans and cold storages indefinitely as the coronavirus continues to cause commerce chaos around the world.

Virus precautions mean that many ships can’t get into Chinese ports, others are stuck at docks waiting for workers to return, and still more are idling in “floating quarantined zones,” as countries refuse to allow crews of ships that have docked at Chinese ports to leave the boat until they have been declared virus-free.

Alaska seafood exports to China of nearly $1 billion include products for their own markets, but the bulk goes there for reprocessing and shipment back to the United States and other countries.

“If you have plants that have product coming in and no workers to fill it, you’re going to get that overflowing cold storage situation. So it’s definitely a problem on the reprocessing side. On the consumption side, if people aren’t going out to eat and going out to the market to buy seafood, that’s going to take consumption down as well. So there’s a couple different ways that it’s working against moving seafood through the supply chain,” said Andy Wink, director of the Bristol Bay Regional Seafood Development Association and an economist who has tracked world salmon markets for more than a decade.

US Commerce Department allocates $35 million for Alaska fisheries disasters

March 2, 2020 — Fishermen affected by the 2018 Pacific cod and Chignik sockeye disasters will soon have access to about $35 million in relief funding.

Secretary of Commerce Wilbur Ross allocated about $65 million to fisheries disaster relief, about $35 million of which is for Alaska, according to a Feb. 27 announcement from the National Oceanic and Atmospheric Administration. Within Alaska, about $24.4 million will go to the Pacific cod fishery disaster and about $10.3 million to the Chignik sockeye fishery. The funding was appropriated when Congress passed the 2019 Consolidated and Supplemental Appropriations Act.

Fisheries disasters can be declared under the Magnuson-Stevens Fisheries Management and Conservation Act when natural disasters or management actions significantly negatively impact stakeholders’ ability to participate in a fishery.

In the case of the Pacific cod fishery in the Gulf of Alaska, scientists are linking the decline in stock abundance to environmental causes; in Chignik, the salmon decline seemed to be linked to poor environmental conditions for sockeye that summer.

Both disaster requests had already been granted, but the amount of funding that the fisheries would have allocated to them was yet to be determined. The National Marine Fisheries Service determines how much funding to allocate to fisheries based on commercial revenue loss information.

Affected fishermen will be able to apply for funding to help with infrastructure projects, habitat restoration, state-run vessel and fishing permit buybacks, and job retraining, according to the announcement from the National Oceanic and Atmospheric Administration.

NOAA investing in Alaska’s mariculture development

February 27, 2020 — The National Oceanic and Atmospheric Administration (NOAA) is investing resources in Alaska, a move seen helping move the state’s mariculture development forward.

The agency has appointed a Regional Office Mariculture Coordinator for the Alaska region for the first time.

Alaska’s Mariculture Initiative has a goal of building a $100-million industry in 20 years. Among Alicia Bishop’s many tasks as regional coordinator is to bring together stakeholders that will help lay the foundation for achieving that goal.

The head of the Task Force that developed the Initiative said the creation of the coordinator position for Alaska signals NOAA’s commitment to the state.

Abnormally Warm Years Caused a Sea Change in Coastal Alaska Ecosystems

February 27, 2020 — Rapidly warming Alaska is already a poster child for climate change, from its vanishing sea ice to its thawing permafrost. But over the last three years, the state’s northwestern coast has experienced a series of unusual climate-related changes—remarkable even for the long-altered Pacific Arctic.

Beginning in 2017, a combination of abnormally high temperatures and unusually strong, southerly winds swept the Bering and Chukchi seas. An alarming cascade of ecological consequences ensued—record-low sea ice, shifting algae blooms, migrating fish populations and sudden seabird die-offs were just a few.

“Most of my own research is with people living in the coastal communities, so talking to them and hearing about what they’re seeing,” said Henry Huntington, an independent Alaskan researcher and consultant. “And they saw some very unusual things, and things that struck them.”

“Ridiculous” water temperatures and unstable sea ice were among the most common complaints raised in interviews with coastal residents, Huntington noted.

“Adding to that, what we’re hearing from folks on the research cruises, it just became apparent that things were really a lot different from what any of us expected,” he said.
