Influence of upwelling on movement of southern bluefin tuna (Thunnus maccoyii) in the Grea

Twenty-nine juvenile southern bluefin tuna were implanted with acoustic tags to study their movement in relation to an upwelling event in the Great Australian Bight. Fifteen individuals were detected 941 times over 62 days, with presence linked to water temperature changes. Parks Australia provides this dataset, originally from the Australian Marine Parks Science Atlas, to highlight research relevant to Australian Marine Parks.

Use Cases

• Modeling predator movement patterns based on acoustic telemetry detection data.
• Analyzing the relationship between tuna presence/absence and upwelling-induced water temperature changes.
• Calibrating correlated random walk simulations against field observations of animal movement.
• Studying short-term school fidelity and medium-term fidelity to bathymetric features in pelagic fish.

Strengths

• Includes data from 29 acoustically tagged fish and 941 detection events.
• Combines multiple data collection methods: acoustic telemetry, 22 aerial surveys, and computer simulation.
• Study design involved tagging at multiple distances (local, 40km, 120km) from a monitoring reef.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update was 2026-07-16.
