Without refrigeration, and a species that can live out of water for some time, the guts get removed fairly quickly after catch. Leaving the nutrient rich gills as the starting point for outside microbes to start working.

 

as do the civil engineering & architectural firms that they rely on.

Having cleaned a lot of tuna (for example) . . . . many fish heads comprise ~1/3 of the whole body - so despite likelihood of fly maggots that were laid in that area it is the right area. Where I've worked for some 37 years - it's a business metaphor - representing the rot at the head works down to the body.
.

 

It's a metaphor for any organization, but for it to have originally gained traction as such, or even be phrased, there would have been some general knowledge about fish starting to rot at the head in the first place.

 

if they had frozen the head fish, there wouldn't be any rot

 

not to get political or anything - but it's a shame we don't have a spare fuel line, just in case one were to fail collapse into the permafrost ..... a spare, maybe like keystone. Baaah - who needs back ups.
Naah - it's not like hackers would ever shut one down

The Keystone Pipeline goes no-where near Alaska's North Slope. It originates at Hardisty Alberta, and has been carrying oil to multiple U.S. Midwest terminals since 2010. Extensions subsequently reached Port Arthur Texas and Houston

It is only the Keystone XL expansion / shortcut (a.k.a. Phase 4) that has been cancelled.

 

Source: CDC document warns Delta variant appears to spread as easily as chicken pox and cause more severe infection - CNNPolitics

The Delta coronavirus variant surging across the United States appears to cause more severe illness and spread as easily as chickenpox, according to an internal document from the US Centers for Disease Control and Prevention. The document -- a slide presentation -- outlines unpublished data that shows fully vaccinated people might spread the Delta variant at the same rate as unvaccinated people. CDC Director Dr. Rochelle Walensky confirmed the authenticity of the document, which was first reported by The Washington Post.
. . .
The CDC is scheduled to publish data Friday that will back Walensky's controversial decision to change guidance for fully vaccinated people. She said Tuesday the CDC was recommending that even fully vaccinated people wear masks indoors in places where transmission of the virus is sustained or high.

^this would be better placed in the covid thread^ but i am most interested to see if the next spread is going to lead to more variants.
otherwise, can the vaccinated just go about their business and decide for themselves whether it is worth the risk or not to mask or unmask.
as for more serious disease, i haven't seen any reports.

 

Many news articles have variable amounts of political vs technical content. I see the CDC and other science based departments as 90% technical and treating their reports as ‘political’ guts the good work they do.

agreed, i would have posted it in the non political covid thread

 

Well, varying is what viruses do. Weird would be if it didn't.

 

We all knew that melting of permafrost and submerged methane clathrates (or hydrates) would release lots of methane, adding to climate change.

But thawing of limestone rocks might release methane too?

Scientists expected thawing wetlands in Siberia’s permafrost. What they found is ‘much more dangerous.’

"But now a study by three geologists says that a heat wave in 2020 has revealed a surge in methane emissions “potentially in much higher amounts” from a different source: thawing rock formations in the Arctic permafrost.

The difference is that thawing wetlands releases “microbial” methane from the decay of soil and organic matter, while thawing limestone — or carbonate rock — releases hydrocarbons and gas hydrates from reservoirs both below and within the permafrost, making it “much more dangerous” than past studies have suggested.

Nikolaus Froitzheim, who teaches at the Institute of Geosciences at the University of Bonn, said that he and two colleagues used satellite maps that measured intense methane concentrations over two “conspicuous elongated areas” of limestone — stripes that were several miles wide and up to 375 miles long — in the Taymyr Peninsula and the area around northern Siberia.

The study was published by the Proceedings of the National Academy of Sciences.

Surface temperatures during the heat wave in 2020 soared to 10.8 degrees Fahrenheit above the 1979-2000 norms. In the long stripes, there is hardly any soil, and vegetation is scarce, the study says. So the limestone crops out of the surface. As the rock formations warm up, cracks and pockets opened up, releasing methane that had been trapped inside.

Further tests showed the continued concentration of methane through the spring of 2021 despite the return of low temperatures and snow in the region."
