Using Inherent Optical Properties to Investigate Biogeochemical Dynamics in a Tropical Mac

A study of biogeochemical and inherent optical properties (IOPs) in the near-surface layer of the Fitzroy Estuary and Keppel Bay system in tropical Australia during the dry season. The dataset includes continuous spectral absorption, scattering, and backscattering coefficients, plus discrete measurements of phytoplankton, nonalgal particles, colored dissolved organic matter absorption, and concentrations of pigments and suspended matter. It was published by Geoscience Australia Data and last updated on 2026-04-30.

Use Cases

• Developing spatially and temporally adjusted remote sensing algorithms based on the observed high variability in optical properties.
• Modeling the impact of semidiurnal tides on biogeochemical constituent distribution across an estuary-coast-ocean continuum.
• Analyzing relationships between suspended matter concentrations and specific particle scattering coefficients mentioned in the description.
• Studying the variability in chlorophyll-specific phytoplankton absorption across highly turbid to clear oceanic waters.

Strengths

• Includes continuous and discrete measurements of spectral absorption, scattering, and backscattering coefficients.
• Captures data across strong spatial gradients, with particle scattering decreasing by 2 orders of magnitude from estuary to bay.
• Sampled spatially and across tidal phases, capturing temporal variability on short scales.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection is limited to the dry season; seasonal variability is not captured.
• Row count is unknown, which may limit suitability assessment.
