Arctic Ocean Prokaryotic Metatranscriptomes with Taxonomic and Functional Annotations

Westmeijer's dataset provides raw metatranscriptomic data supporting the analysis in 'Low prokaryotic growth efficiency enhances the carbon demand estimate for the Central Arctic Ocean'. The 188.6 MB dataset contains transcripts per million (TPM) values for each open reading frame (ORF), along with assigned taxonomy and functional annotations. It was last updated on 2026-04-28 and is shared under a CC-BY-4.0 license.

Use Cases

• Estimating prokaryotic carbon demand in the Central Arctic Ocean based on gene expression levels.
• Analyzing the taxonomic composition of active prokaryotic communities from assigned taxonomy data.
• Investigating functional gene expression profiles related to biogeochemical cycles using functional annotations.
• Correlating transcriptional activity with environmental parameters discussed in the associated publication.

Strengths

• Dataset size is 188.6 MB, indicating a medium-scale analysis.
• Data includes three key components: ORF TPM counts, taxonomy assignments, and functional annotations.
• Associated with a specific, peer-reviewed scientific publication, providing context and validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• Description metadata is limited; actual data quality requires manual inspection after download.
