The met team with big grins on our faces when we finally find treasure (or maybe just a box of electronics) a mere 2 and a half metres down. We were a bit worried we were going to hit the sea. We have lots of instruments that have to be raised every year to stop them getting buried which means lots and lots and lots and lots of digging.
When I'm turning the pumps on and off I have to hold my breath so i don't contaminate the sample. We do this every week, come rain or shine, and send back all the flasks at the end of the year.
