Sturmflut

I'm giving up maintainership of the #Subsurface dive log package on #Flathub. There is a too wide gap between how it is developed and what Flathub/Flatpak expects, and I still can't use the Flathub version with my own dive computer because there are Bluetooth issues I have no idea how to debug.

I cannot justify investing more time on an application I use at most three times a year. Especially when the official #AppImage just works.

New Method Reveals Hidden Activity of Life Below Ground dri.edu/new-method-reveals-hid

Species-resolved, single-cell respiration rates reveal dominance of sulfate reduction in a deep continental subsurface ecosystem: Melody Lindsay et al. pnas.org/doi/10.1073/pnas.2309

"deep wells in the #DeathValley regional flow system provide windows into #subsurface environments... one of them contains several key #microorganisms that are only found in the deepest South African #GoldMines"

[broadly, a 'seismic' listening technique could help researchers map water movement, moisture levels in soil, with these researchers at Caltech have figured out a way to use vibrations from passing cars to see how much water sits directly beneath the ground’s surface…]

Hidden #biosphere discovered beneath world's driest hot desert
phys.org/news/2024-04-hidden-b

Persistent #microbial communities in #hyperarid #subsurface habitats of the #Atacama Desert academic.oup.com/pnasnexus/art

"In the upper 80 cm of playa sediments, microbial communities were dominated by #Firmicutes. Below 200 cm, a different microbial community was discovered, dominated by #Actinobacteria... this community might have colonized the soil 19,000 years ago, before being buried by playa deposits"
