Health risks on the Antarctic Peninsula – what’s happening with the ozone hole, UV exposure, environmental change and funding for Antarctic science?

I recently had a paper published in Antarctic Science – I don’t think that it’ll set the world on fire but it was quite interesting in how it came about so I thought I’d write a blogpost about it.

The study

The measurements for the study were taken by a team who sailed across the Drake Passage and then then spent some time on and around the Antarctic Peninsula. They deployed a small “badge” each day that responds to sunlight in a way that allows you to subsequently work out how much UV radiation they were exposed to. From these measurements we concluded that the UV exposure experienced was comparable to temperate, mid-latitude locations in the spring/late summer. Obviously the team was very well covered as it’s cold down there but this can nonetheless have impacts on the eyes and exposed skin.

This is quite important as the ozone “hole” over Antarctica is likely to be about as bad as it will get before recovering over the next few decades and exposure risk might increase in this region if there are significant environmental changes (e.g. further warming, ice sheet retreat). This paper represents something of a pilot study so I’d love to get a more rigorous experiment up-and-running one day.

The study’s origins: networking on social media

The idea for the experiment and the paper first came about on twitter. Someone I’d never previously worked with (or met) invited me along to a planning meeting for the 2012 British Services Antarctic Expedition (BSAE) simply because I had a twitter account where I posted interesting stories about Antarctica.

I then cobbled together a tiny bit of money from the Royal Meteorological Society and the Royal Geographical Society (with the Institute of British Geographers) to get the badges produced and analysed at the University of Manchester.

I was quite impressed that we managed to get a relatively interesting bit of work done with so little resource. Which brings us on to…

…funding for Antarctic science

Budgets for science have not been increasing recently so perhaps it’s time that we have to start thinking of less traditional ways of getting work done. My example might not be particularly useful as it all happened largely by accident! However, there’s an interesting piece in The Conversation by Adrian McCallum about the role of private funding in Antarctic research that is probably more informed on this topic. Might be worth a read if you’re thinking of this type of thing.
