Airbursts and the Pacific whale population decline

The population of Pacific gray whales has plummeted to its lowest point since the 1970s, with record-low calf numbers, following a period of "unusual mortality" from 2019 to 2023. Scientists are concerned that environmental changes, particularly in Arctic feeding grounds influenced by sea ice decline and ecosystem alterations, are impairing the whales' ability to reproduce and survive. Despite previous resilience, recent data suggests the gray whale population may be struggling to adapt to rapidly changing ecological conditions, raising alarms about their long-term recovery prospects. Pacific gray whale numbers have dropped to their lowest since the 1970s, with a significant decline in calf populations. The recent decline follows a period of an "unusual mortality event" from 2019 to 2023, which significantly reduced population numbers. 

What scientists are saying: Researchers suspect that changes in Arctic feeding grounds, driven by climate change and sea ice loss, are impacting whale reproduction and survival. The current population estimates are around 12,900 adults and 85 calves, down from previous counts of over 19,000 whales. The decline in calf numbers correlates with reductions in sea ice cover in the Bering and Chukchi seas, affecting nourishment and reproduction. Stranded dead whales along the West Coast, some emaciated, indicate ongoing health issues possibly linked to food scarcity. Experts emphasise that the population’s ability to rebound rapidly is declining, indicating stress on the gray whale's resilience in a changing environment.

Reality: See June 2 post (Fireballs and Gray whale strandings timeline in California), and May 10th post (San Francisco Bay Cetacean deaths). These two particular posts and others point out that meteor airbursts are the primary cause of whale deaths unrelated to ship strikes and net entanglement.

The great escape - dodging cosmic bullets

2025, June 21. Southern Ocean. Airburst. Coordinates: (61.3 S, 157.9E). Time: 20:55. Altitude: 56.3 km. Energy: e = 3, -e = 0.1 or 100,000 kg/TNT. Velocity was NA.

Whales escaped north just in time. Everything has been quiet in the last two months, with only one event over land in Mexico. This one was timed by nature after cetacean migration was well underway, with many whales seen along New Zealand and Australian coasts. Unfortunately, it shows this region of the Southern Ocean is susceptible to meteor airbursts. It is also not a high-energy event and was moderately high when detected. There was some activity in the west of the Australian continent in the previous months; however, it wasn't significant. New South Wales had some bright arrivals, but this happened and stopped before the whales arrived. New Zealand has been quiet, which is unusual, so this all has added up to whales being rather happy with the situation. I hope it remains that way. It also shows that we need to bank the animals and stop slaughtering them, because nature changes and when it does, cetaceans will feel the full force of it.

Large Fireball in Mexico

2025, June 15. Mexico (northeastern), Santiago and several municipalities in Nuevo León. Large Fireball. Time: at 2:10 am. Travelling S.W. A loud sonic boom was reported, delayed and concurrent. Fragmented. Color ranged from light blue, green, light yellow, orange and white. The event lasted around 12 seconds and was widely reported across Nuevo León and Tamaulipas. The object was detected by the GOES 18 and 19 satellites. Possible fall 30 km northwest of the San Roberto junction and Highway 57. The object was so large it was visible from neighboring states, including Tamaulipas, Coahuila, and parts of southern Texas, United States. This event occurred 500 km north of the airburst on May 31st.

Marine Animal Disturbance Alert for Western Australia

2025, June 7. Western Australia, Great Australian Bight, 460km south of Perth. Meteor. Shower (Daytime Arietids). Coordinates: (B -36.14, 116.06, E-36.70, 114.95). Velocity: 43km/s. Duration: 2.04 seconds. Height B to E: 103-96km. Another one that started 7 minutes later on the mainland, broke up on entry. With the migration season well underway, a Marine Animal Disturbance Alert should be noted for the SW coastal region of Western Australia. Areas such as Busselton and Bunbury are at higher risk.

Third airburst in Mexico region Updated 20250604

An airburst over land in Mexico brings the tally to three in just over 6 months. The cumulative energy released is 6.8 kt or 6,800,000 kg/TNT. The other two occurred over the Pacific Ocean. This meteor activity has profoundly affected cetacean activity in the region, with its ramifications felt north along the USA west coast. 

2025, May 31. Mexico, Hidalgo State, Xiliapa. Airburst. Coordinates: (98.8 W, 21.1 N). Time: 23:06. Energy: e = 38.6, -e = 1 or 1,000,000 kg/TNT. Altitude: 47.3 km. Velocity: 17.8 km/sec.  

Also: 

2025, May 29. USA, Oregon, Cachalot (sperm whale). Adult male, measured approximately 53 ft long. Cause of death: It appears to have been due to a pre-mortem vessel strike interaction.

2025, June 1. UK, Cleethorpes. Dead dolphin.

2025, June 1. UK, Cleveleys beach. A dead porpoise. It’s the latest porpoise to wash up on a Fylde coast beach in recent months, with others discovered on beaches in Fleetwood and Blackpool.

2025, June 2. USA, Massachusetts, Cape Cod Bay. Fireball. Time: 20:07EDT Seen in Connecticut, Maine, New Hampshire, New Jersey and Rhode Island. A Marine Animal Disturbance Alert should be noted for this region due to historical data showing it as a cetacean stranding hotspot. Update: Cancel Alert due to information suggesting this event was above the inland coast, not water. 

San Fransico Bay Cetacean deaths

Date: 2025, May 7. USA, California, San Francisco Bay, Treasure Island. Dead female Gray whale. The 38-foot-long whale showed no obvious signs of trauma or injury and had been feeding recently.

This recent death brings the 2025 total whale deaths to six, with over 30 seen in the bay this year alone. Only one fatality showed signs of a ship strike. In 2024, only 4 Gray whales were seen, with two deaths recorded.

An unconfirmed report from Mexico says: "In Baja California Sur, at least 94 gray whales have been found dead so far in 2025." I think this number includes other baleen species. I'm working on obtaining official figures. 

Once again, for those not familiar with my other posts, two large meteor airbursts were detected by NASA over the last six months in Mexico's Pacific region. See map below. Combined, they had the energy of 5.8 kt or 5,800,000 kg/TNT.

Cetacean strandings since April 17

 2025, April 17. USA, California, San Diego, Nahant Court in Mission Beach. A dead dolphin.

2025, April 17? UK, Anglesey, beach near Rhosneigr (Porth Tyn Tywyn). Dead bottlenose dolphin.

2025, April 19. USA, Washington, near Cape Disappointment, Ilwaco, Long Beach, about four miles north of Seaview. A female dead gray whale. The whale was the fifth reported dead in Washington so far this year. Note: Two dead whales washed up along the Oregon coast last spring, and three others washed up in the span of a week in January 2023. Two of those five were also gray whales; the other three were a fin whale, a humpback whale and a sperm whale.

2025, April 17. Cambodia, Kampot province, Trery Koh commune. A pink dolphin ws found dead off shore. It weighed about 50kg and was 1.98 meters long.

Beaked whale washes ashore in Mexico

2025, April 21. Mexico, San Antonio del Mar. Dead beaked whale.

Note: There have also been beaked whale strandings in Iceland, the Philippines (the largest known individual ever) and New Zealand. I can only suggest the wording as a global cluster. In all likelihood, I will find further cases or others that will never be recorded.  

Meteor airburst shows how devastating they can be when they occur over the ocean

Small Airburst in Australia. It's incredible to think that it was only 82,000 kg/TNT. What if it had been in the millions, or even just in the hundreds of thousands? Then imagine this over water and above cetaceans. The one off the coast of Mexico on March 27 was 2.4 million kg/TNT. 

2025, April 21. Australia, New South Wales, near Queensland border at the Gibraltar Nature Reserve. Airburst. Coordinates: (29.1 South, 151.6 East). Travelling NW or NNW was seen from Melbourne in Victoria to Bundaberg in Queensland, over 1600 km apart. Colour: Blue-Green. Energy: e = 2.3 × ^10j. -e = 0.082 or 82,000 kg/TNT. Altitude: 41km. Velocity: NA. Time: 09:27 UT, 19:23 AEST. The sound had delayed and concurrent properties. The sonic boom was heard at Stanthorpe (NSW) 58km away and was described as “a massive boom”. At Sandy Flat, houses were shaken shortly after the meteor exploded. A witness stated they, “saw the flash from lounge room window and shortly after heard a big bang, shaking the house like bad thunder”. 

The trajectory in the map below is preliminary.

Meteor activity in Mexico

The atmosphere in Mexico is active at the moment. Two major meteor airbursts occurred in the Pacific Ocean in recent months. The first occurred in December and has corresponded with the increased whale strandings. This large fireball created a sonic boom that was heard as a low rumble.

Alarming toll from Meteor Airbursts

These incidents are not isolated. According to NOAA, the U.S. has seen a troubling rise in whale strandings and deaths in early 2025:

Over 81 gray whales have been found dead along the Pacific Coast since January.

13 deaths have occurred in San Francisco Bay alone.

At least 70 gray whales died earlier this year in the lagoons of Baja California, Mexico—their traditional wintering ground.

Two Large Meteor Airbursts.

2024, December 20. Pacific Ocean. Airburst. 204 km S.W off the coast of Puerto Escondido, Mexico. Energy: 3,400,000 kg.TNT. Altitude: 32.6 km. Velocity: 21.1 km/sec.

2025, March 27. Pacific Ocean, 920km WSW of Manzanillo, Colima, Mexico. Large Airburst. Energy: 2,400,000 kg/TNT.

Gray whale stranding in Mexico

2025, April 5. Mexico, Costa Baja, La Paz Bay. A dead Gray whale in an advanced state of decomposition has washed ashore. 

This is a crucial issue in Mexico, hence the post. I will place a weekly update on further cetacean strandings later.

Cetacean strandings and meteor events since the 22nd of March

2025, March 22. UK, North East and Cumbria, Redcar beach, Teesside. Dead Porpoise.

2205, March 24. Canada, Haida Gwaii, Graham Island, Rose Spit. A large whale found in advanced state of decomposition.

2025, March 25. Scotland, Fife, Torryburn Beach. Dead porpoise.

2025, March 25. Ireland, Waterford Estuary. Sperm whale in estuary. Unusual.

2025, March 27. Pacific Ocean, 920km WSW of Manzanillo, Colima, Mexico. Large Airburst. Coordinates: (14.3N, 111.5W). e = 104.5, -e = 2.4 or 2,400,000 kg/TNT. Altitude: 38.1km. Vel: 21.3km/s. Marine Animal Disturbance Alert. This comes after the December 20 airburst at the same latitude, 1443 km to the east. Two very significant events. Due to this event, cetaceans such as Humpback and Risso's dolphins could be vulnerable. Gray, for this event, is not as much due to its location. This brings the 2024-2025 airburst ratio to 3:13. A comet not seen in 160,000 years is entering the inner solar system, so it will be interesting to see what it brings with it. The MAD'S for Brazil and the central Indian Ocean are still in effect to this date.

2025, March 29. USA, San Fransisco Bay, Alcatraz Dock. Dead Gray whale.

2025, March 29. British Virgin Islands, Caribbean Sea. Dead humpback whale floating at sea.

Marine Animal Disturbance Alert for Mexico, central American countries and USA

Marine Animal Disturbance Alert.

2025, March 27. Pacific Ocean, 920km WSW of Manzanillo, Colima, Mexico. Large Airburst. Coordinates: (14.3N, 111.5W). e = 104.5, -e = 2.4 or 2,400,000 kg/TNT. Altitude: 38.1km. Vel: 21.3km/s.

This comes after the December 20 airburst at the same latitude, 1443 km to the east. Two very significant events. Due to this event, cetaceans such as Humpback, Orca, and Risso's dolphins could be vulnerable. Gray is not as much due to its location. The upcoming migration season could see whale stranding all the way to Pacific NW. 

This brings the 2024-2025 airburst ratio to 3:13. A comet not seen in 160,000 years is entering the inner solar system, so it will be interesting to see what it brings with it.

The MAD'S for Brazil and the central Indian Ocean are still in effect.
