PSO Gabi Stowasser (British Antarctic Survey) and Co-PSO James Bradley (Mediterranean Institute of Oceanography) onboard the RRS Sir David Attenborough, on #SD049 in Antarctica

First time Co-PSO 🙋‍♂️
Hugely grateful to Gabi Stowasser - our brilliant PSO (Principal Science Officer) who I learnt a lot from as Co-PSO.
As with all expeditions/projects - on a cruise there is an enormous amount for the PSOs to keep on top of besides the science 😵‍💫
Gabi steered us to success 💪 #SD049
