Nine Orcas Have Died in Fishing Gear Near Alaska This Year

An unusually high number of orcas have died this year after getting caught in commercial fishing equipment off the Alaskan coast, according to the National Oceanic and Atmospheric Administration (NOAA). This uptick in deaths, per a trade association representing local fishers, may be connected to a “new behavior” from the animals.

Since the start of this year, nine orcas—also known as killer whales—have died in groundfish trawl fisheries in the Bering Sea near the Aleutian Islands. Another became entangled but was released alive, per NOAA, bringing the total number of “incidentally caught” orcas to ten so far in 2023.

For comparison, just five orcas in the Bering Sea died or became seriously injured after entanglement in fishing gear during the five-year period between 2016 and 2020, according to NOAA statistics.

The federal agency is now investigating the incidents to confirm the cause of death (because it’s possible some orcas were already dead before being caught) and to conduct genetic testing to determine which population they belong to, per the statement. As of now, experts do not believe the animals are part of the Southern Resident population, a critically endangered group off the coast of the Pacific Northwest, writes Insider’s Katie Hawkinson.

This year, some fishers have observed a novel behavior among orcas that might be related to the recent entanglements, according to a statement from Groundfish Forum, a trade association that represents 19 trawl vessels.

“In 2023, our captains have reported an increase in the number of killer whales present near our vessels, where they appear to be feeding in front of the nets while fishing,” per the statement. “This new behavior has not been previously documented and marine mammal scientists are not sure why this change has occurred.”

Orcas are clever, social animals that can learn new behaviors from each other. These crafty creatures have figured out how to exploit human fishing activities, such as by snacking on fish caught on longlines. Once one orca figures out an opportunistic feeding technique, scientists say, others can learn from watching and follow suit, per Live Science’s Sascha Pare.

That may be what’s happening this year near Alaska. To try to get to the bottom of the recent deaths, Groundfish Forum asked Hannah Myers, a marine biologist at the University of Alaska Fairbanks, to spend a week aboard a fishing vessel in May, reports the Anchorage Daily News’ Hal Bernton.

During that time, roughly two dozen orcas arrived when the vessel started fishing operations—and they stuck around.

“Certain pods were targeting the vessel, and I think it’s very lucrative behavior for them, because they are staying with the vessel 24/7,” Myers tells the Anchorage Daily News.

Using an underwater microphone, Myers recorded orcas making clicking sounds that scientists think may be connected to foraging behaviors. Based on the recordings, the mammals seemed to be following the net as the vessel towed it deep underwater; she also observed them at the surface as fishers pulled the nets up from the depths. These behaviors are “high-risk” for the orcas, she tells the publication.

Additionally, Myers noticed orcas hanging out near discharge chutes, where fishers send accidentally caught halibut—a prohibited species—back into the water.

Groundfish Forum, for its part, says it does not release halibut into the water when orcas are nearby. Its members are “committed to finding solutions to this unprecedented challenge,” per its statement. “Vessels are experimenting with gear modifications that may prevent whales from entering the net.”

Entanglement deaths concern scientists because orcas are slow to reproduce, meaning that even a few mortalities could affect population numbers more broadly in the future. However, orcas do appear to ramp up breeding efforts if several of their pod members die, per the Alaska Department of Fish and Game.

“Much remains to be learned about the reproductive behavior of killer whales,” the department writes.

An estimated 50,000 orcas live in oceans around the world, with roughly 2,500 of them living in the eastern North Pacific Ocean, per NOAA.

Under the Marine Mammal Protection Act, enacted in 1972, vessel owners or operators must report to NOAA all deaths or injuries of marine mammals, such as orcas, that take place during their operations.

In addition to the ten orca entanglements in the Bering Sea this year, NOAA is also reviewing a separate incident that occurred on June 7. On that day, an orca became entangled and died during Alaska Fisheries Science Center’s longline survey for sablefish and groundfish on the Central Bering Sea slope.

Sky Watch Alaska: planets align plus the aurora forecast

Sky Watch Alaska: planets align plus the aurora forecast


ANCHORAGE, Alaska (KTUU) – This is a great time of year to do some star gazing. If you have clear skies in your part of Alaska, take the time to check out the night — and morning — sky.

After sunset, look toward the southwest. Saturn and Venus are snuggled up together (of course, they are more than 800 million miles apart) in the evening sky. They set at about 9:40 p.m. in Southcentral.

Before 9:40 p.m., you can see four planets with the naked eye — Saturn, Venus, Jupiter and Mars. Jupiter and Mars stick around through the morning. Mars is very close to the moon right now.

The Aurora forecast is fairly weak for the next few weeks. That’s not to say there won’t be the occasional burst but overall, solar activity is expected to be fairly low until the beginning of February.

Short-lived cold snap, with another warming trend this weekend


ANCHORAGE, Alaska (KTUU) – Temperatures across the state are cooling off, as our strong low from the weekend moves into the Chukchi Sea. This will set up for colder air to spread across the state this week, as another short-lived cold snap is expected. While some light snow is possible for the Interior, areas of the Slope and Western Alaska, Southcentral will stay on the drier side until the night. Meanwhile, Southeast will continue to hold onto moderate rain with gusty conditions.

SOUTHCENTRAL:

Temperatures this morning are 10 to 20 degrees colder than yesterday, as colder air has settled back into Southcentral. Clear skies and calm winds are evident this morning for parts of the region, with light snow falling through the Copper River Basin. We’ll see fairly quiet conditions today, outside of Kodiak which will see increasing snow and rain into the afternoon and evening hours. This comes as our next area of low pressure moves up the Alaska Peninsula.

We’ll see light snow spreading north across the Kenai overnight into Wednesday, with light snow expected through Prince William Sound. Several inches are likely through the Kenai and Chugach Mountains, with the pass expected to see a couple of inches of accumulation. Western parts of the Kenai will see the potential for a few inches, while inland areas of Southcentral largely stay dry. If Anchorage and surrounding locations see any accumulation, it’ll amount to less than half an inch.

As snow tapers off Wednesday, we’ll see the return to colder and drier conditions into Thursday. Thursday may be the coldest day this week across the region, before another warming trend carries us into next week. Right now holding with snow through early next week, but areas of wintry mix are possible as highs warm above freezing.

SOUTHEAST:

The winter storm warning for Skagway and higher elevations expired at 6am this morning. While some light snow showers are still possible, little accumulation will occur the rest of the day. Scattered to periodic showers are occurring elsewhere across Southeast today, with less than half an inch of rainfall through the day. Any moisture available into the evening will see a transition to some wintry mix or snow into Wednesday morning. However, the better chance will come from another low lifting north into the panhandle. Any snow and wintry mix we see for Wednesday will primarily stay confined to the central and southern panhandle. We’ll see much cooler weather taking hold this week for Southeast.

INTERIOR:

Some areas of light snow are possible this morning, with less than half an inch to be expected. While temperatures are still warm for much of the Interior, highs will steadily fall throughout the day. Many areas will see lows bottom out near or below zero by tomorrow morning. We’ll see high pressure keep things dry and sunny through the next couple of days, with the coldest stretch of weather from Wednesday morning into Thursday morning. Much like the rest of the state will experience, a warming trend arrives this weekend. We’ll see the return to highs in the 20s, with some snow in the forecast. Be prepared for some gusty conditions through the Alaska Range by the close of this week.

SLOPE/WESTERN ALASKA:

Areas of light snow and blowing winds will continue to impact the Slope, with a winter weather advisory remaining in place for the Central Brooks Range and the Beaufort Sea Coast. Both locations will see up to 1 inch of snow and gusty winds up to 35 mph. While the winter weather advisory will expire for the Central Brooks Range this afternoon, the Beaufort Sea Coast will see the alert continue into Tuesday evening. Snow and blowing snow will be the primary impact today, with a return to colder weather through the rest of this week, this comes as high pressure settles into the area.

The storm responsible for the damaging winds for Southcentral over the weekend, has pushed north into the Chukchi Sea. We’ll still see some light snow accumulations for Western Alaska, with 1 to 3 inches expected. Some fo the heaviest snow will fall across the Seward Peninsula and the Western Brooks Range.

An area of low pressure in the Bering Sea will keep gusty winds and snow in the forecast for Gambell/St. Lawrence. Be prepared for heavy snow at times and areas of reduced visibility. Overall, colder weather will settle into Western Alaska, with the possibility of morning fog in the valleys over the next few mornings.

ALEUTIANS:

Some light areas of snow will occur for the Pribilof Islands and into parts of the Alaska Peninsula today, as a weak low moves up the Peninsula. This will be the main focus for snow into Wednesday for Southcentral. This low will bring heavy precipitation and gusty winds for the Eastern Aleutians and the Alaska Peninsula. Looking ahead through the rest of the week, we can expect to see more a ridge beginning to build into the region. This ridge will slowly shift east, keeping several upper level disturbances traversing the Aleutians. Temperatures will remain fairly warm in the 30s and 40s.

OUTLOOK AHEAD:

Model consensus continues to agree on another warming trend heading our way into next week. This stretch of warmth will likely lead to many spots cementing themselves within the top warmest January’s on record. While we’ll spend the rest of this week on the colder side, highs steadily climb this weekend into next week. We’ll see highs in Southcentral climbing back above freezing, with areas of the Interior climbing back into the 20s.

Have a safe and wonderful Tuesday!

Anchorage, Alaska hit by hurricane-force winds, structures damaged across city


Associated Press

Hurricane-force winds cause widespread damage in Alaska’s largest city

Thousands of residents across Alaska’s largest city were still without power Monday, a day after a powerful storm brought hurricane-force winds that downed power lines, damaged trees, forced more than a dozen planes to divert, and caused a pedestrian bridge over a highway to partially collapse. A 132-mph (212-kph) wind gust was recorded at a mountain weather station south of Anchorage. A large low-pressure system in the Bering Sea brought the high winds, moisture and warmer than average temperatures — in the low 40s Fahrenheit (slightly over 4.4 degrees Celsius) — to Anchorage on Sunday, said National Weather Service meteorologist Tracen Knopp.
