AAP Project 4501: Mapping, predicting and monitoring ecological change in the Southern Oce

Data from 2000 to 2016 on demersal fish abundance and environmental variables from the Kerguelen Plateau in the Southern Ocean. The record contains environmental data, R code, and model outputs from a project using hierarchical models to map and predict ecological change. The Australian Ocean Data Network hosts this data, which originates from the Australian Antarctic Division's Random Stratified Trawl Survey program.

Use Cases

• Modeling species community changes based on hierarchical models (HMSC) mentioned in the description
• Mapping demersal fish distribution based on catch per unit effort (CPUE) data
• Predicting ecological change based on paired environmental and trawl survey data
• Analyzing temporal trends in fish assemblages from 2000 to 2016

Strengths

• Data spans a 16-year time range from 2000 to 2016
• Includes environmental data paired with biological survey data for modeling
• Project outputs include R code, facilitating reproducibility

Limitations

• Raw trawl survey data requires separate authorization from AFMA and is not directly included
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
