Tracking data from polar bears (N=67) and ringed seals (N=60) in Svalbard that were equipped with various tracking devices and used for analysis that is the basis for the scientific article: Hamilton, C. D., Kovacs, K. M., Ims, R. A. , Aars, J. and Lydersen, C. 2017. An Arctic predator-prey system in flux: Climate change impacts on coastal space use by polar bears and ringed seals. J. Anim. Ecol. 86: 1054-1064. The data set consists of info on animal ID, time, location and species.

Colored dissolved organic matter (CDOM) absorption in seawater and sea ice. Samples filtered through 0.2 µm membrane filter. Absorbance was measured with Shimadzu UV-2401 PC spectrophotometer and 50 or 100 mm quartz cells in the wavelength range 240 to 700 nm. Absorbance was converted to absorption coefficients based on cell length. A baseline correction was applied.
