  • 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.
