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!
A bright, colourful map titled 'TECTONIC MAP OF THE SCOTIA ARC'. The map covers South America, the Scotia Sea, South Georgia and the South Sandwich Islands, and the Antarctic Peninsula. Bathymetry is shown with varying shades of blue.

We ran a Map Giveaway for BAS staff & students this week, raising money for @mapaction.bsky.social! The maps were a mixture of beautiful, historical maps from the 70s and 80s, and previous versions of our main published maps. We had so much interest - thanks BAS for the support & generous donations!
2 people looking at some of the maps in the giveaway. A large piece of artwork showing an icy landscape can be seen on the wall behind the maps. An image of a poster advertising the giveaway. The text on the poster reads 'MAGIC Map Giveaway' and some old maps are shown faded in the background. One of the old maps available in the giveaway. The title is 'British Antarctic Territory - Trinity Peninsula'. The map is a Directorate of Overseas Surveys (DOS) map from 1974 with artistic hillshading on land and a faded blue sea. BAS staff members looking at some of the maps. 4 people can be seen looking at large paper maps placed on tables. The room has a large black screen in the background, and big glass windows/doors leading out to a balcony.

We just attended #FOSS4GUK in Leeds. It was a fantastic couple of days meeting other GIS & software enthusiasts to learn about WWII coordinate systems, making maps accessible & much more, all using free & open tools anyone can use! We also presented the code and history behind our new map catalogue.

We're working on a new project to support building & modernisation at Rothera Research Station. This week we took part in a workshop showcasing how we will integrate 3D Building information models with our GIS platform and how it will form a key part of infrastructure planning and asset management.
Building Information Model (BIM) of our new Discovery Building at Rothera. The image shows a 3D building with curved edges to the roof, and the building wall closest to us has been removed in the image, allowing us to see inside. A communications tower can be seen on top of the building. A 3D scene on our GIS platform showing building models in geographical context with other mapping layers such as roads, cables and masts. Snow-covered areas and rocky outcrops can be seen outside of the main station area. The roads and paths are shown in red. Part of the runway can be seen on the right.

We've recently been testing our new laser scanner, acquired this year to enable accurate scanning of our facilities. It’s capturing in 3D now! MAGIC supports BIM modelling in Antarctica, where buildings will be scanned into point clouds to record detailed features - not even a socket will be missed.
The new laser scanner placed outside on some grass. A panorama of a scan output inside one of our workshops. A yellow glider can be seen on the floor. A panorama of a scan output inside one of our workshops. Some poster stands can be seen on the left, as well as a glider on the right.

Iceberg A23A is currently located north of South Georgia & over the weekend has fragmented into a several large pieces. While these individual icebergs are large & may get new names, they may be short lived as further breakup is now likely as currents push them all further north into warmer waters.
A satellite image from 1st Sep. showing the island of South Georgia covered in snow and ice, and iceberg A23A lying about 65 km to the north. There are many clouds in the image. The berg remains as one large piece, with multiple smaller fragments around its edge. The largest fragment is still 35 km in length. A scale bar is shown in the bottom right corner, and a credit statement saying "Copernicus Sentinel-3 imagery acquired 1st Sep. 2025".

@bas.ac.uk hosts 'Pre-Deployment Training' each year, for those going to Antarctica. Everyone attending receives a couple of maps in their pack and we've been busy printing and collecting up these maps ready for the event! Nothing beats a map to help orient people for their exciting adventure ahead.
A small selection of the maps being prepared for Pre-Deployment Training (PDT) at BAS. There are maps of Bird Island, Thatcher Peninsula, Signy Island, the Antarctic Peninsula, and the Brunt Ice Shelf, amongst others. Some of the maps have nice scenery photos on their front cover.

Made primarily of polystyrene they weigh just 1.6 kg on take-off, but despite this they are capable of operating in the stronger winds we experience down in the Antarctic with a maximum continuous wind limit of 17 m/s. In fact, yesterday we clocked a top ground speed of >63 mph!

Lots of dots! These are spot heights generated for our Air Operations Planning Maps, using REMAv2 2m tiles. Next steps are to clean up the density, add existing GPS points & then add them to our maps, which are used for planning by pilots across the continent. The data will then be openly published!
A screenshot of 59,261 spot heights in West Antarctica and the Antarctic Peninsula. This is the initial version, before reducing the density. Each point is shown as a red dot, the coastline of Antarctica is displayed as a grey line, and the yellow squares are the extent of some of the REMA tiles.

We've been busy on a new project making polygon boundaries for place names, using Alexander Island as a case study.
Creating polygons for Antarctic names is about more than cartographic precision. It’s about improving how we understand, search, & use data in one of Earth’s most remote environments.
An in-progress screenshot of two polygon boundaries in northern Alexander Island - the boundaries are for the Rouen Mountains and Havre Mountains. The map contains a hillshade, and place name locations are displayed with red points.
