Discovery · The Life Scientific: Lucy Carpenter · 11 May 2026 podcast

We did think it could have been longer than that.

But yes, these are the things that happen.

You know, you were on the path of massive tropical storms that go past.

Yeah, it was going to happen and it did.

I think we had a wish.

It was our aspiration that it would be a long term site.

You know, you set something like that up.

You don't want it to be a three or four year project.

But as you know, the challenge in the funding environment, no one gives you money for 25 years time.

What you have to do is you have to set something up on short term funding.

And we were very lucky to make inroads at some interesting scientific places.

At that time, we'd seen this coastal phenomena, seaweeds giving halogens.

What had never been seen was the coexistence of these halogens and the smoke and gun for the chemistry, which is ozone being destroyed.

Normally, if you go to most sites, you'll see this is ozone at ground level increasing during the day because the pollution that gives rise to it means that once the sun comes out, ozone increases.

So you have to be in this really clean environment to see the ozone loss processes occurring, in this case, the halogens.

So we were there and day after day after day, as soon as we started measuring ozone, we could see these daily cycles where the sun came up and ozone was destroyed.

And then it comes up again at night because it's been transported in.

We expected that to some extent because it is destroyed by photolysis.

But when we applied our models to it, we found that almost twice as much ozone destruction was going on than you'd expect from the traditional chemistry.

So we were lucky that we had measurements from the University of Leeds on the halogen oxide radicals, and we were able to quantitatively tie the two together through models and say, you know, due to the presence of these halogen molecules, we're getting 40% more ozone destruction than you would expect without them.
