UK scientists from across maritime research are uniting to map the seabed along the UK’s south‑west coastline.

Data gathered through the survey will support a range of activities, helping to build a more complete & authoritative picture of the UK’s marine environment.

Had an excellent time attending UKAS 2026 in Bristol this past week. Heard a lot about new isotope work within archaeological science and presented some of my modelling work. Looking forward to the next meeting in 2028!

Scarborough is a favourite seaside destination for many reasons but for a rock lover, its geology is fascinating.

Here, BGS' @meljleng.bsky.social takes us on a whistlestop tour of the local rocks, as well as some other fascinating sites in the area.

Lovely to see the cinnabar moth caterpillar feeding on the ragwort at BGS. The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings.
