A discussion on the new service Open Polar: The Global Open Access Portal for Research Data and Publications on the Arctic and Antarctic (https://openpolar.no). Presenting only freely available documents on the Arctic and Antarctic, Open Polar is a thematic search engine that can be a useful tool for both researchers and decision makers. Tamer Abu-Alam explains the reasons for filtering out all research documents that are not available in open access, thereby promoting open science. Of the 1,8 million records currently included in Open Polar, approx. 22,5 percent are research datasets, which makes the service unique. Host: Per Pippin Aspaas.
