Field school in u/w recon and low-viz mapping

IMH will hold a four-day field school in underwater reconnaissance by sidescan sonar, and site mapping in low-visibility water.  Tentative dates are 15-16 and 22-23 August 2009.

The school will be based at Tall Timbers MD.  It will comprise one day ashore and one day afloat, for divers and non-divers, and two days in the water mapping two wrecks in the lower Potomac (divers only).

Space is limited, but some slots are still available.  If more people sign up than we can accommodate, we will offer it again later in the year.

Mapping techniques to be taught in the field school will include perpendicular offsets, trilateration with and without a baseline, and the Direct Survey Method.  A training manual will be provided for the course.

Students should also read "Underwater Archaeology: the NAS Guide to Principles and Practice," 2nd edition.  It is a superb book, available through or by special order through bookstores.  We have two loaner copies if you don't want to buy it.  First come first served.
