In biology/geology "#marinesnow" refers to the #organicdebris of organisms from higher #waterlevels. The #carboncycle thus transfers #CO2 to the #seabed, thus binding the #greenhousegas.
B. Borer et al. (2026) found that #microbial components of this "snow" induce #calciumcarbonate #dissolution in higher waters, reducing their #settlingvelocity and requiring consideration in future #climatemodels.

Fig trees convert atmospheric #CO2 to stone

Some species of #figTrees store #calciumCarbonate in their trunks – essentially turning themselves (partially) into stone, new research has found. The team of Kenyan, U.S., Austrian, and Swiss scientists found that the trees could draw carbon dioxide (CO2) from the atmosphere and store it as calcium carbonate ‘rocks’ in the surrounding soil.

Pamukkale, Turkey 🇹🇷

These rocks that look a bit like limestone cave formations growing on a substrate of basalt (a rock not known for growing such things) are tufa (calcium carbonate) that were deposited with the help of algae, so said the sign at Picnic Cave, a short way down the ledge. It means cyanobacteria, blue-green algae. Tufa forms underwater. These were formed when Lake Lahontan covered over the area, likely when its height was controlled by overflow over Darwin Pass, which is about the same height.

Back to US-50, I completed the circle through Nevada with one last little hike joining a pair of interpretive trails outside Fallon. The interpretive trail at Grimes Point showcases the 8000 year old petroglyphs of the area. The interpretive trail at Hidden Cave showcases the geology including the tufa with its human connections.

"#Foraminifera #protists... build a shell, several hundred micrometers in size, which is made of #CalciumCarbonate... these #calcite structures are highly sensitive to changes in seawater #chemistry... This is reflected in an accelerated decrease in shell weight during the 20th century."

"#Foraminifera are tiny, single-celled organisms that live in the #oceans. Their hard shells, made of #CalciumCarbonate, can withstand the test of time and their #fossils reveal a lot about Earth's history, including past climates and environments."

Oh, yeah. The latest developments about my quest to return to a more or less good night of sleep.

I did not need earplugs, but now I do.

I did need white noise, but now I don't.

I've switched my anti-reflux medicine from generic Tums (calcium carbonate) to a proton pump inhibitor.

Temperature lowered from 74F to 72F. (That's 3.293 cats to 3.143 cats for those who measure in cats.)

My last few nights have been interrupted by me peeing.
