Horizontal and Vertical Movements of Atlantic cod and European plaice in the North Sea and English Channel from 1996 to 2010 Derived from Data Storage Tags
This data is derived from the deployment of archival data storage tags (DST) on Atlantic cod (Gadus morhua) and European plaice (Pleuronectes platessa) in the North Sea and English Channel. Tags were deployed throughout the time period 1996 – 2010. The dataset includes 107 individual fish each with its own bivariate time series of horizontal (m day-1) and vertical movements (m day-1). Daily geolocation estimates (latitude and longitude) are also provided. The length of each time series varies substantially from a minimum of 40 days to a maximum of 399 days.
A description of tag type, fish capture, tag attachment and tag accuracy can be found in Righton et al. (2010) for Atlantic cod and in Hunter et al. (2004) for European plaice. Righton et al.

Each DST was pre-programmed to record depth (m) at 10-minute intervals for the duration of deployment. Vertical movement rates were calculated as the absolute difference between corresponding 10-minute depth measurements summed to the daily level. 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). Second, the straight-line distance between daily geolocations is calculated using the Great Circle equation. Pedersen et al.

Neat et al. (2014) previously used the daily geolocation estimates provided in this dataset as part of their study into stock structure in Atlantic cod around the British Isles.
