Marine Bacterial Community Assembly in Maxwell Bay Antarctica During Summer 2022

Surface seawater samples collected sequentially during the 2022 austral summer in Maxwell Bay, Antarctica. The dataset likely contains bacterial community composition data derived from 16S rRNA gene amplicon sequencing, used to quantify deterministic and stochastic assembly processes. The research was authored by Haiyu Zeng and shared via figshare.

Use Cases

• Modeling the relative contribution of deterministic vs. stochastic processes in microbial community assembly based on phylogenetic null model analysis.
• Analyzing correlations between community structure shifts and environmental factors like water temperature, silicate, and nitrate concentrations.
• Investigating the link between nitrate drawdown and increased relative abundances of dominant bacterial genera.
• Developing predictive models for polar marine biogeochemical cycles based on quantified environmental selection mechanisms.

Strengths

• Data is focused on a specific temporal window (2022 austral summer) and geographic location (Maxwell Bay, Antarctica).
• Analysis quantified a specific deterministic process contribution (homogeneous selection at 84.68% in February).
• Environmental variables collectively explained more than 50% of the observed variation in community structure.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (13.9 KB), suggesting limited scope or summary data.
