I recommend not using paper at all. I've found that there is no such thing
as water-proof paper. When we survey reefs, we use PVC plastic slates. If
you buy a big thin sheet, cut it yourself, sand the edges, and drill a
little hole to tie a string for the pencil or to tie it to your BC. Making
slates is fairly cheap, and it works well. You can custom cut them to the
size and shape you want, and you can put a permanent template on them with
a permanent marker. If the PVC is too shiny to write on, sand down the
front and back a little. Denser PVC tends to sink, and lighter PVC floats.
You may buy small pieces to test them out in salt water. Or, if you don't
want to go through the hassle, you can buy slates from a company.
If you want the reef survey on paper and have access to a
photocopier, you can photocopy the slates when you get back to dry land or
you can do it the old-fashioned way and transfer the data by hand. Hope
your project goes well!
