Counting Walruses from Space
Despite their importance to Arctic ecosystems, we don’t know how many walruses exist. We’re using satellite images and citizen science to count walruses.
My research interests are to develop the use of space technology for marine wildlife research in remote places, and make this method applicable at a global oceanic scale by improving the efficiency of image analysis through crowdsourcing and automated systems.

Despite their importance to Arctic ecosystems, we don’t know how many walruses exist. We’re using satellite images and citizen science to count walruses.
This project is creating a long-term framework for monitoring whale numbers and behaviour.
Many populations of wildlife are remote, inaccessible or difficult to monitor. The advent of sub-metre, Very-High-Resolution (VHR) satellite imagery has enabled us study these animals in a much more efficient way.
In the first successful attempt to calibrate walrus counts from satellite imagery, scientists used drones to validate animal counts in Svalbard, Norway.
The shortlist has been announced for The Natural Environment Research Council’s (NERC) Impact Awards 2023. Four BAS projects have made the shortlist and commended list, ranging from biodiversity and ecology to space weather.
