Spiny Dogfish Satellite Telemetry Data from Atlantic Canada

Pop-up Satellite Archival Tags (PSATs) deployed on 6 female spiny dogfish from 2008 to 2009 collected depth, temperature, and light-level data. Three of the six tags successfully reported data, with deployments lasting from 75 to 234 days. The processed data includes maximum likelihood position estimates and depth-temperature profiles.

Use Cases

• Analyze depth and temperature profiles to model spiny dogfish vertical habitat use in Atlantic Canadian waters.
• Use ambient light-level data for geolocation position estimation to reconstruct individual shark movement paths.
• Correlate tag-derived environmental data (e.g., temperature) with external datasets like NOAA OI SST for oceanographic studies.
• Examine deployment metadata, including fork length (80-96 cm) and time at liberty, to study tag performance and animal behavior.

Strengths

• Data originates from 6 direct animal deployments using Wildlife Computers PSAT Mk10 tags.
• Includes processed outputs from specialized software (GPE3) using external reference datasets for SST and bathymetry.
• Time series covers deployments from 75 to 234 days, providing longitudinal behavioral data.

Limitations

• Small sample size of only 6 tagged animals, with only 3 tags successfully reporting data.
• Data is temporally limited to deployments from 2008-2009, potentially not reflecting current conditions.
• Geographic scope is restricted to Atlantic Canadian waters where commercial fishing vessels operated.
