Special shoutout to first author Alyzza Calayag (not yet on Bluesky)! This was a strong collaboration between @geomarkiel.bsky.social and @awi.de especially @taylorpriest.bsky.social and @matthiaswietz.bsky.social — and others not on bluesky

We also, surprisingly, found that the viruses are detected in the southern ocean (‘bi-polarity’) as well as indications of cold-adaptation, indicating that these observations may also be relevant there, but remain to be further explored.

But we also found striking increases in virus-to-microbe ratios in late summer — suggesting that if you want to understand the impacts of viruses in the strongly seasonal Arctic, it’s very important when you are there.

We tracked viral communities across seasons — and found strong seasonal patterns and striking late-summer shifts in virus–host dynamics.

Yes, there’s seasonality in Arctic virus community composition…

🚨 In case you missed it… our 4-year time-series analysis of Arctic Ocean viruses is out now!

Near-monthly samples — including through the dark, cold, polar winter ❄️ — using long-read metagenomics.
