International Research Team Discovers A Potential Source Of Abiotic Methane In The Arctic Ocean
![Raman optical observations at 10× and 100× showing original halite hopper crystal and microbial movement within fluid inclusions entombed within the crystal structure. (A) Entire halite cubic crystal showing rectangular fluid inclusions on all four faces with an air bubble on the left face. Scale bar is at 100 μm. (B) Enhanced image of (A) showing fluid inclusion patterns within cubic halite habits. Scale bar is at 100 μm. (C) 100× image highlighting a fluid inclusion within a single crystal. Red arrows show microbial movement. Green targeting dot highlights an entombed biomass. Scale bar is 2 μm. (D) Another 100× image showing a larger fluid inclusion [when compared with (C)] with increased microbial movement within the fluid inclusion. Scale bar is 2 μm for 2C,D. -- Astrobiology via Sage Journals](https://astrobiology.newspackstaging.com/wp-content/uploads/2025/11/Evaporitic-Preservation-of-Modern.png)
