RHaMBLe - RRS Discovery
Reactive Halogens in the Marine Boundary Layer
2007
The RHaMBLe campaign is an attempt to improve our understanding of the role of halogens in the marine boundary layer. The first project took place in Roscoff, France in September 2006, where the University of Leeds ground-based FAGE instrument measured iodine monoxide (IO) for the first time. After this success, the aircraft HOx instrument was adapted to measure IO on the RRS Discovery.
On the three week cruise track, we sailed south from Lisbon to the Cape Verde Islands (where we stopped to visit the Cape Verde Atmospheric Observatory) had a bit of a wander around the coast of Mauritanian (over the upwelling) before taking a zig-zag route north to Falmouth in the south west of England. After some initial teething problems and a sampling issue, we measured IO in June 2007 through the Canary Islands on the way home!

I kept a blog of the first half of the cruise before work completely took over. Have a look for a more informal look at how things went!

We had to undergo sea survival training. Life jackets are just not designed for women!
The Cape Verde Atmospheric Observatory has a 25 m tower. This is me standing at the top on a not too windy day! Considering I know who built the tower and I'm not brilliant with heights, I was just pleased I made it down again!
