The cod was tagged in the North Sea on 03/04/2001 and was recaptured in the North Sea on the 06/02/2002. The cod migrates north from the tagging location off Lowestoft, and spends the summer off the north-east coast of the UK, north of the Dogger Bank. The dataset contains 309 days of data, and comprises three files: depth measurements at a 10 minute sampling rate for the full record, depth measurements at a 10 sampling rate for July 2001, and estimates of horizontal position for each day.

(2010). Righton et al. (2010) is published in Marine Ecology Progress Series and is freely available here `Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima`_. The data storage tag was pre-programmed to record depth (m) at 10-minute intervals for the duration of deployment, and depth at 10s intervals for the month of July 2001. Horizontal movement rates were calculated in a two-step approach. First, daily geolocations were estimated via a Fokker-Planck-based method that combines a tidal location method and a Bayesian state-space model (see Pedersen et al. 2008 for model details).
