Benthic Habitat Maps with Biogeochemical and Seasonal Data for Jervis Bay, Australia

Winter and summer benthic habitat maps for a sandy embayment in Jervis Bay, Australia, created by Geoscience Australia Data. The maps integrate physical sediment properties, biogeochemical variables, and infaunal diversity data from surveys in August and February. The dataset was last updated on 2026-04-20.

Use Cases

• Modeling species turnover across seafloor patch-types based on combined sediment and biogeochemistry data.
• Analyzing temporal changes in benthic diversity patterns linked to reactive carbon and redox conditions.
• Comparing the effectiveness of different habitat map types (sediment-based, biogeochemistry-based, combined) for differentiating biological communities.
• Studying spatial and temporal variation in biogeochemistry and sediment composition within visually homogeneous areas.

Strengths

• Includes a temporal component with data from both winter (August) and summer (February) surveys.
• Integrates multiple data types: physical sediment properties (%mud, sorting, %carbonate), biogeochemical variables (chlorophyll a, sulfur, metabolism, bio-available elements), and infaunal analyses.
• Provides spatially continuous data layers generated using Boosted Decision Tree and cokriging models.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the single study location and two survey months.
