Australia's marine research community generates rich observational data across biodiversity, biogeochemistry, and physical oceanography domains, yet routinely transforming these into products consumable by national assessment processes — State of the Environment reports, Environmental Economic Accounts, and environmental approvals — remains a persistent institutional challenge. NESP Marine and Coastal Hub Project 5.9 addresses this gap by building reproducible, scalable data infrastructure that converts heterogeneous research datasets into cloud-optimised, assessment-ready products sustained through IMOS and AODN national infrastructure.
A stakeholder-driven prioritisation workshop engaged policy, monitoring, and data communities to identify six priority datasets spanning seagrass, kelp forests, seabirds, dugongs, vessel traffic, and benthic imagery. Reproducible ETL pipelines ingest, harmonise, and validate each dataset using Darwin Core standards, WoRMS and CAAB taxonomic registries, and H3 hexagonal spatial indexing. Output products delivered in Apache Parquet format achieve greater than 88% compression relative to source files while enabling efficient remote querying — qualities essential for integration with national reporting dashboards and species distribution modelling workflows.
Pipelines are operationalised within AODN infrastructure with automated refresh cycles, ensuring datasets remain current alongside ongoing monitoring programmes. A practitioner-focused training programme builds organisational capacity to extend and maintain these pipelines beyond the project. This work demonstrates a replicable institutional model for bridging routine marine observation and the recurring national assessment cycles required under Australia's Nature Positive Plan, contributing practical infrastructure to Australia's emerging marine data commons.
