In the first successful attempt to calibrate walrus counts from satellite imagery, scientists used drones to validate animal counts in Svalbard, Norway. On this International Day for Biological Diversity, the researchers describe how this study is a big step towards using satellite imagery as a non-invasive method to monitor walruses in the Arctic.
An international team of scientists led by the British Antarctic Survey have published research on using new technology to study mass stranding of whales from space and how the technology could be used to help protect populations.
