Marine Bacterial Community Assembly in Maxwell Bay, Antarctica During Summer 2022

Table 2_Temporal succession and assembly of marine bacterial communities in Maxwell Bay, Antarctica during summer.docx contains data from a study on Antarctic microbial ecology. Haiyu Zeng collected surface seawater samples sequentially during the 2022 austral summer and performed 16S rRNA gene amplicon sequencing and phylogenetic null model analysis. The dataset was last updated on March 19, 2026.

Use Cases

• Quantifying deterministic vs. stochastic assembly processes based on phylogenetic null model analysis.
• Analyzing temporal succession of bacterial communities based on sequential sampling during summer.
• Modeling the influence of environmental factors like temperature, silicate, and nitrate on community structure.
• Investigating correlations between nutrient drawdown and relative abundances of dominant bacterial genera.

Strengths

• Data is from a specific, well-defined geographic location: Maxwell Bay, Antarctica.
• Temporal sampling was sequential during the 2022 austral summer.
• Analysis quantified the relative contribution of deterministic processes, with a specific figure (84.68%) for homogeneous selection in February.
• Environmental variables collectively explained more than 50% of the observed variation in community structure.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (14.4 KB), indicating limited scope.
