The detection of eddies in the Lofoten Basin from daily satellite altimeter data for the 26 year time period (1993-2018) is done using the automated hybrid algorithm described by Halo (2012). The automated hybrid algorithm described by Halo (2012) combines the closed contours of streamlines of the sea-surface height (Chelton, Schlax, and Samelson 2011) and Okubo-Weiss parameter (Isern-Fontanet, García-Ladona, and Font 2006; Chelton et al. 2007). Eddies were tracked in space and consecutive time-steps with reference to the centres of eddies, in a generalized non-dimensional property space, following the method proposed by Penven et al. (2005). The dataset provides latitude and longitude positions of individual 5373 anticyclonic and 5589 cyclonic eddies identified during the time-period 1993-2018. Details of non-linearity parameter is given in Raj et al. (2020) Eddy properties such as eddy intensity, radius, amplitude,vorticity, translational velocities are also provided. ...
