Satellite imagery has helped scientists discover a new walrus haul-out site. And it's sparked a call for your help! 📢
To safeguard their future, we urgently need to understand how they’re affected by the climate crisis.👇

We've recently created a new collection of legacy maps in our Catalogue, which will be added to over time. For now, we have 3 interesting maps available to view and download: data.bas.ac.uk/collections/...
The Scotia Arc is one of our favourites. The map was a massive compilation effort at the time!

This is Latady Island(pronounced la-tarday) in the Bellingshausen Sea in Antarctica. It is 115 km long, but as far as we can see from BAS records no human being has ever landed on it.
