Benthic Habitat Maps with Biogeochemical and Seasonal Data for Jervis Bay

Winter and summer benthic habitat maps for a sandy embayment integrate sediment and biogeochemical variables to analyze infaunal diversity. The dataset, from the Australian Ocean Data Network, includes physical (%mud, sorting, %carbonate) and biogeochemical (chlorophyll a, sulfur, metabolism, bio-available elements) parameters collected in August and February. Boosted Decision Tree and cokriging models generated the spatially continuous layers, which show how biogeochemistry and %mud vary spatially and temporally.

Use Cases

• Modeling species turnover across seafloor patch-types based on abiotic parameter combinations.
• Analyzing seasonal influences on infaunal diversity patterns based on reactive carbon and redox data.
• Comparing the effectiveness of sediment-based versus combined sediment/biogeochemistry-based habitat maps for differentiating biological communities.
• Spatial interpolation and mapping of benthic variables using cokriging models mentioned in the description.

Strengths

• Includes both winter (August) and summer (February) surveys, providing a temporal component.
• Combines multiple data types: physical sediment properties, biogeochemical measurements, and infaunal analyses.
• Data layers were generated using spatial modeling techniques (Boosted Decision Tree and cokriging) for continuous coverage.

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.
