Great to see some work being done to the surface on the #canal towpath in #Edinburgh. Here at Bridge 6A. They seem to be working their way west filling potholes and smoothing over dangerously bumpy roots... #CyclingInEdinburgh #CyclingToWork

Great to re-connect with old friends & colleagues at the #OSM26 in Glasgow. Gerhard Herndl was an amazing mentor. Astrid & I worked together on our MSc projects (haven't seen her since 1996!). Alexander never knew it but he was a great role model during my Undergrad years.

Brightish morning in #Glasgow: today: 5th and final day at #OSM26. Been an amazing meeting. Great response to my #deepsea #ecotoxicology poster and talk, and met up with colleagues I haven't seen in 20, and in some cases, 30 years! #lifeofanacademic markhartl.hw.ac.uk
