Well it takes a long time to write up all my experiences, check through all the photographs etc but at long last here is my first blog from my visit earlier in the year with dive with Purpose.
Well I have arrived in the USA to help out with two very important project. First I will be helping the youths from Dive with Purpose in an ongoing project to document a ship wreck and then I will be helping them, restore a coral reef. I can’t wait to get in the water again. My diving bell is too big to transport to the UK and so I only get to explore underwater properly when I am in the USA.
Here I am with Ken Stewart and the superintendent at Biscayne National Park Brian Carlstrom
Charles Lawson who is the park archeologist
Justine Benanty another archeologist
Dave Conlin the Submerger Office Chief
Before we can dive on the wreck we need to practice the necessary skills on land first.
Everything will be much harder to do when we try to do it underwater.

The students will be using a survey method called trilateration which uses the Side-Side-Side (maths) Theorem to generate a map to scale of the shipwreck. Very complicated for a little bear like me, so I let the youths get started and I helped out where I was needed.

Surveying wreck sites used to be done by laying a grid over the wreck and then recording the details in each square. The trilateration technique of mapping doesn’t require permanent grids
Everyone knew what they needed to do and the activity was accomplished with some great team work.
I spent some time working with one of the youths Adrian Baptiste and he wrote the following blog entry.
