MODIS Aqua Chla
This resource is daily means of Chla measured by the Aqua satelite which represents phytoplanton in the water for the periods 2018-2023 and 2022-2023.
The Aqua satellite platform carries a MODIS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. There are multiple retrieval algorithms for estimating Chl-a. These data use the OCI method (Hu et al 2012, doi: 10.1029/2011jc007395) recommended by the NASA Ocean Biology Processing Group and implemented in the SeaDAS processing software l2gen. The OCI algorithm is described at https://oceancolor.gsfc.nasa.gov/atbd/chlor_a/ (and links therein).

- Purpose
- This data and sets of maps was generate as inputs to the Futures of Seafood study State of Play (Work Package 1).Futures of Seafood delivers Australia's first comprehensive analysis of how intensifying ocean demands will reshape seafood production. This landmark 18-month study examines the cumulative impacts of competing ocean uses and policy decisions on the seafood sector. By uniting industry expertise with research capabilities, it creates a single source of truth about challenges and opportunities facing Australian seafood. Through spatial mapping, economic modeling, and social impact assessment, it provides decision-makers with essential insights for managing multiple ocean industries and ensures sustainable seafood production amid changing ocean access.
