This data is derived from the deployment of a single data storage tag on an
Atlantic cod (Gadus morhua) in the English Channel. The cod was tagged in the
Southern North Sea on 25/03/2005 and was recaptured in the Eastern English
Channel on the 09/01/2006. The cod migrates down through the English Channel,
resides in the Celtic Sea and then returns. The dataset contains 291 days of
information. Each day consists of 144 vertical movement rates (in metres), one
horizontal movement rate (in kilometres) and one turning angle (in radians,
from -pi to pi). Vertical movement rates have been log (natural log)
transformed.
