Distinct bacterial community structures with abundant carbon degradation and sulfur metabolisms found in different sea-ice types from the Central Arctic Ocean | Microbiology Spectrum
The Arctic region is warming nearly four times faster than the global average, leading
to the continuous replacement of its thick multi-year sea ice with thinner first-year
ice. The reduction in Arcti...

Comparative metagenomics indicates metabolic niche differentiation of benthic and planktonic Woeseiaceae - Environmental Microbiome
Background Benthic microbiomes exhibit remarkable temporal stability, contrasting with the dynamic, substrate-driven successions of bacterioplankton. Nonetheless, understanding their role in carbon cy...

Loss of sea ice alters light spectra for aquatic photosynthesis - Nature Communications
This study deduces from first principles how sea ice and seawater shape light spectra in fundamentally different ways. The loss of sea ice may thus trigger changes in both the pigment and species comp...

So happy to finally meet @venkatachalam.bsky.social in Ny-Ålesund after probably a decade of missing each other while working in Svalbard. Thanks for the visit to Himadri Station, nice discussions and collaboration ideas for future Polar and Alpine microbiology research. See you in Goa 😉❄️🦠🔬🌊🧊
