The training program has a modular structure, starting with a one-day introductory training and progressing through the NAS I, NAS II and NAS III certificates and finally the certification of the NAS IV part. The program is open to everyone and the introductory course does not require any prior qualifications and the program is designed to allow you to get involved as per your interest with trainings in a wide range of subjects and fields of nautical archeology. , there is something for Everyone!

The NAS Part 1 training is open to 10 to 24 participants. The schedule can be personalized, but includes classroom sessions on Friday evenings and Saturday mornings. On Saturday afternoon, we create a “shipwreck” on dry land for the students to study, on Saturday evening we take our “shipwreck” to the bottom of a confined water pool. On Sunday, students will dive at a local site to test their skills on a real shipwreck.

The NAS training program was first developed by the Nautical Archeology Society to train divers working on the archaeological record of the Mary Rose, the flagship of King Henry VIII. Today, the aim of the programs is to develop an understanding of underwater archeology and to teach people the practical skills they need to work at an underwater archeology site. You don't need any previous training or experience - and you don't need to be a diver to take the course. Non-divers can participate in work out of the water for their team.

NAS training focuses on surveys of underwater sites. The objectives of NAS I are:

  1. Introduce the basic concepts of underwater archeology;
  2. Introduce underwater mapping and recording techniques;
  3. Provide a hands-on opportunity to develop mapping and recording skills with supervision.

The Nautical Archeology Society is dedicated to developing an interest in our underwater cultural heritage and advancing education in nautical archeology. It aims to preserve our underwater archaeological heritage by involving everyone - divers and non-divers, scientists, historians and anyone interested.
