CEMP cameras data validation experiment at the Galindez Island gentoo penguins (Pygoscelis papua) colonies

We inform on the results of data validation experiment provided for pictures from time lapse cameras of the CEMP camera monitoring project of CCAMLR at Galindez Island gentoo colonies. During the 2017-2018 season biologists winterers at Vernadsky station, situated at Galindez Island, provided continuous observations every day of gentoo nests in the three sites where automatic time lapse cameras installed. The results of visual observations have been compared with data from camera pictures, which registered the same nests that were observed. The comparison of the lay, hatch, and crèche dates demonstrates the reasonable correspondence within 1-2 days between visual observations and data, obtained by pictures processed.
