I wrote in a previous post about members of my local dive club participating in an introductory course in marine archaeolgy on 28th April.

That article covered the first 2 parts of the course, whereas this article covers the final part of the course where we all got wet in a local swimming pool to try and translate the stuff we’d learnt in the classroom and on the outdoor, ‘dry’ exercise into practise.

The photo shows an underwater frame, which is one technique of surveying all or part of a dive site. The other technique we used…

… involves taking relative measurements from one or more fixed line/s (datum) that are set-up on the dive site.

Doing this type of thing was great fun, but also highlighted what you take for granted on ‘dry land’.

Underwater, you aren’t able to talk to your buddy other than through primative sign language, writing on a slate is harder, and you need to remember to breathe ;-)

Overall a very busy and interesting one-day course.

We all plan to do the next level course later in the year, so watch this space for a review of that.
