This dataset accompanies the paper 'Antarctic Marine Viruses: A Review and Future Perspectives' and compiles quantitative data on Antarctic marine viruses, including sampling locations, viral abundance, lytic viral production, carbon release by lysis, associated environmental factors and others. The primary aim of this dataset is to consolidate existing measurements on Antarctic marine viruses, facilitating future research on viral ecology, biogeochemical cycling, ecosystem dynamics, climate modelling in polar marine environments.

This dataset includes the genome assembly and predicted proteome of an Antarctic sea-ice diatom, Nitzschia sp. (most likely Nitzschia stellata). It also contains the endogenous viral element (EVE) sequences identified within this diatom genome, as well as the results of comparative genomic analyses between Antarctic sea-ice diatoms and non-polar diatoms. The Nitzschia sp. genome assembly was obtained through metagenomic binning of Antarctic sea-ice samples.
