BLUE WHALES GONE SILENT?! CLIMATE CHANGE? ALL ENERGY USED TO FIND ENOUGH FOOD - KRILL

THE WEEK : BLUE WHALES NOT SINGING -CLIMATE CHANGE

Excerpt: The study tracked over six years of acoustic monitoring in the central California Current Ecosystem. During those years, blue whale sounds decreased by approximately 40%.

"We don't hear them singing," John Ryan, a biological oceanographer at the Monterey Bay Aquarium Research Institute and the lead author of the study, said to National Geographic. They are "spending all their energy searching." There's "just not enough time left over" for singing, and that "tells us those years are incredibly stressful." It's like "trying to sing while you are starving,"

"When we have these really hot years and marine heat waves, it's more than just temperature," Kelly Benoit-Bird, a marine biologist at Monterey Bay Aquarium and co-author of the study, said to National Geographic. "The whole system changes, and we don't get the krill." So the animals that "rely only on krill are kind of out of luck." High ocean temperatures lead to algal blooms that can kill krill. And blue whales are "forced to forage over a much larger geographic area when krill populations become depleted," said Newsweek.

Marine heat waves are only going to get worse due to fossil fuel usage. Oceans act as the world's largest carbon sink, meaning they "already absorb more than 90% of the excess heat from climate change," said The Independent. There are "whole ecosystem consequences of these marine heat waves," said Benoit-Bird. If whales "can't find food and they can traverse the entire West Coast of North America, that's a really large-scale consequence."

BLUE WHALES ARE THE LARGEST ANIMALS ON OUR PLANET!

LEAF SHAPED FANGS?! PACIFIC DISCOVERY LINKS UNPRECEDENTED FIND! GINKO BEAKED WHALES

Unprecedented!   OOOOH this is great!

UNION RAYO: GOODBYE TO DECADES OF ASSUMPTIONS : GINKO BEAKED WHALES

Excerpt: For the first time in history, a team of scientists managed to see, record and document the elusive ginkgo-toothed beaked whale (Mesoplodon ginkgodens) swimming in open sea, off the coast of Baja California, Mexico. And the best part is that with this encounter they also solved a mystery that had been puzzling experts for more than a decade, a mysterious acoustic signal, the famous BW43, that no one had managed to attribute to a specific species.

.... For the first time, a species known only from stranded remains was alive, recorded, confirmed!!! Now scientists can track this species without seeing it, just by listening to its signals in the ocean.


Battles, wounds and sharks

The ginkgo-toothed beaked whale has a distinctive feature and it is that the males develop two flat leaf-shaped teeth near the tip of the snout. They do not use them to eat, but to fight with other males for the females.

The photos show long scars, cuts, white lines, many battles on their backs. In addition, many had circular bite marks made by sharks called “cookie cutters”.

CLAM ANALYSIS SHOWS NORTH ATLANTIC SUBPOLAR GYRE ACTING STRANGELY

LIVE SCIENCE : MASSIVE SYSTEM OF ROTATING OCEAN CURRENTS ACTING STRANGELY

Excerpt: An analysis of clam shells suggests the North Atlantic subpolar gyre has had two periods of destabilization over the past 150 years: one around 1920 and the other from 1950 through present. ....

"It's highly worrying," study lead author Beatriz Arellano Nava, a postdoctoral research fellow in physical geography at the University of Exeter in the U.K., told Live Science. "The subpolar gyre was recently acknowledged as a tipping element. We still need to understand more of the impacts of a subpolar gyre abrupt weakening. But what we know so far with the few studies that have been published is that it would bring more extreme weather events, particularly in Europe ... and also changes in global precipitation patterns."

.... But the other signal was a total surprise, she said. The clam data revealed that the subpolar gyre was unstable for a few years in the run-up to the 1920s North Atlantic regime shift. This previously described event was characterized by the strengthening of currents in the gyre. Instability in the subpolar gyre likely caused the 1920s regime shift, and the timeline suggests the period of instability may have reflected the subpolar gyre's recovery from its Little Ice Age collapse, Arellano Nava said.

CALIFORNIA : VERY LITTLE PLASTIC BEING RECYLCLED

LA TIMES - Environment : VERY LITTLE PLASTIC BEING RECYCLED IN CALIFORNIA 

Excerpt:  Polypropylene, labeled as #5 on packaging, is used for yogurt containers, margarine tubs and microwavable trays. Only 2% of it is getting recycled. Colored shampoo and detergent bottles, made from polyethylene, or #1 plastic, are getting recycled at a rate of just 5%.

Other plastics, including ones promoted as highly recyclable, such as clear polyethylene bottles, which hold some medications, or hard water bottles, are being recycled at just 16%.

No plastic in the report exceeds a recycling rate of 23%, with the majority reported in just the single digits.

CALIFORNIA BANS ALL PLASTIC SHOPPING BAGS

 No More Plastic Bags: All plastic carryout bags, including thicker reusable ones, are banned at checkout.

  • Paper Bags Required: Retailers must provide recycled paper bags for a minimum fee of 10 cents each
    .
  • Fee Retention: Stores keep the 10-cent fee to cover bag costs and educational efforts.
  • Increased Recycled Content: By 2028, paper bags must contain at least 50% post-consumer recycled content.
  • Applies To: Supermarkets, large retailers with pharmacies, convenience stores, and food marts. 

WHAT HAPPENS WHEN A WHALE DIES IN THE OCEAN ? : WHALE FALL - NOURISHING AN ENTIRE ECOSYSTEM

NATURAL HISTORY MUSEUM : UK : WHAT HAPPENS WHEN WHALES DIE 

Excerpt:

Whale carcasses take decades to fully decompose and can provide food for an entire ecosystem on the dark depths of the ocean floor. ...Decay sets in soon after the death of a whale, as the insides begin to decompose. The animal then expands with gas and sometimes floats up to the ocean's surface, where it can be scavenged by sharks and seabirds.

Eventually the ocean giant will begin to sink, falling kilometre after kilometre, until finally coming to rest on the seabed. This is when the carcass becomes known as a whale fall.

Whale falls can nourish an entire ecosystem of deep-sea creatures, from large scavengers to microscopic bacteria. They provide inhabitants of the mostly deserted ocean floor with a sudden and immense source of food...

WHAT HAPPENS WHEN A WHALE DIES BEACHED? THIS IS KINDA GROSS! THEY CAN EXPLODE!

This is an older article from the Guardian in September 2022

GUARDIAN : ENVIRONMENT : WHALE STRANDINGS : WHAT HAPPENS TO DEAD WHALE BODIES?

Excerpt: Two mass strandings in Tasmanian waters in a week has left about 200 pilot whales and 14 sperm whales dead. ... In warmer climates, the internal decomposition of dead whales can result in spontaneous explosions. Gut bacteria in the whales can multiply quickly, producing large quantities of methane gas. “If the rest of the body is still intact – if the outer layer, the blubber, is still intact and not broken up – then it can lead to an explosion,” Meynecke said.

In 2004, the decomposing carcass of a 60-tonne, 17-metre sperm whale expoded on a busy streetin the Taiwanese city of Tainan, “showering cars and shops with blood and organs and stopping traffic for hours”. ...
