Benthic Habitat Maps with Biogeochemical Factors for Jervis Bay

Winter and summer benthic habitat maps for Jervis Bay, Australia, incorporate biogeochemical variables like chlorophyll a and sulfur. Patch-types were constructed using abiotic parameters from August and February surveys, including sediment properties and bio-available elements. The dataset, hosted by the Australian Ocean Data Network, demonstrates that including biogeochemistry and time provides a better framework for interpreting biodiversity patterns than sedimentology alone.

Use Cases

• Comparing the effectiveness of different habitat maps for differentiating biological communities based on sediment and biogeochemical parameters.
• Modeling species turnover and diversity patterns based on reactive carbon and redox conditions.
• Analyzing spatial and temporal variation in biogeochemistry and sediment mud content within visually homogeneous seafloor areas.

Strengths

• Includes data from two distinct temporal surveys (August and February), enabling seasonal comparison.
• Integrates multiple data types: physical sediment properties (%mud, sorting, %carbonate), biogeochemical variables (chlorophyll a, sulfur, metabolism), and infaunal analyses.
• Provides spatially continuous data-layers generated through 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 bias inherent to the single study location, Jervis Bay.
