White Shark Recapture Data from NSW SMART Drumline Program, 2015-2022

Seven years of capture-mark-recapture data from the Shark-Management-Alert-in-Real-Time (SMART) drumline program in New South Wales, Australia. The dataset includes 890 tagged white sharks with a 24.5% recapture rate, providing insights into spatial use patterns. Author Gonçalo G. Ramos published the data on figshare in 2026.

Use Cases

• Modeling shark movement patterns based on recapture distances and locations
• Analyzing seasonal habitat use based on recapture timing (Austral winter/spring)
• Investigating size and sex-specific habitat preferences based on recapture rates for smaller individuals and females
• Assessing the effectiveness of non-lethal bather protection programs based on recapture data

Strengths

• Data spans seven years, providing a substantial temporal window for analysis
• Includes 890 tagged individuals with 218 recaptures, offering a significant sample size
• Recapture distances and timing are quantified (e.g., average ~220 km, ~45% within 90 days)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the New South Wales coastline
