1,573 Giant Virus Genomes Assembled from Polar Metagenomes

Polar ecosystems, including Arctic and Antarctic seawaters, saline lakes, and sea ice, are the source for 1,573 giant virus metagenome-assembled genomes (GVMAGs). The dataset was reconstructed from 1,198 polar metagenomes and is authored by Jianyi Feng. It was last updated on May 18, 2026.

Use Cases

• Comparative genomics of giant viruses based on assembled genome sequences
• Analysis of viral community structure in polar ecosystems based on metagenomic sampling
• Investigation of viral adaptation to extreme cold and saline conditions based on polar habitat metadata

Strengths

• Contains 1,573 assembled giant virus genomes, providing a substantial genomic resource
• Derived from 1,198 metagenomes, suggesting a broad sampling effort
• Covers multiple polar environments: seawaters, saline lakes, and sea ice

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
