An Advanced European Scientific Diver is a diver capable of organizing a scientific diving team. He/she may attain this level by either a course or by in-field training and experience under suitable supervision or by a combination of these two methods.

The AESD must:

  • show proof of theoretical knowledge and a comprehensive understanding of:
    • Diving physics and physiology, the causes and effects of diving related illnesses and disorders and their management.
    • The specific problems associated with diving to and beyond 30m, calculations of air requirements, correct use of decompression tables.
    • Equipment, including personal dive computers and guidelines as to their safe use.
    • Emergency procedures and diving casualty management.
    • The principles and practice of dive planning and the selection and assessment of divers.
    • Legal aspects and responsibilities relevant to scientific diving in Europe and elsewhere.
    • Dive project planning.
  • Be fully competent with/in:
    • Diving first aid, including CPR and oxygen administration to diving casualties.
    • SCUBA rescue techniques and management of casualties.
    • The use and user maintenance of appropriate SCUBA diving equipment, including dry suits and full face masks.
    • Basic small boat handling, and electronic navigation.
    • Supervision of diving operations.
  • Be fully competent with:
    • Search methods, such as those utilizing free swimming and towed divers together with remote methods suitable for a various range of surface and sub-surface situations.
    • Survey methods, both surface and sub-surface, capable of accurately locating and marking objects and sites.
    • The basic use of airbags and airlifts for controlled lifts, excavations and sampling.
    • Basic rigging and rope work, including the construction and deployment of transects and search grids.
    • Underwater navigation methods using suitable techniques.
    • Recording techniques.
    • Roped/tethered diver techniques and various types of underwater communication systems such as those utilizing visual, aural, physical and electronic methods.
    • Sampling techniques appropriate to the scientific discipline being pursued.
  • Show proof of having undertaken 100 open water dives, to include a minimum of:
    • 50 dives with a scientific task of work, such as listed above.
    • 20 dives deeper than 20m of which 10 dives deeper than 29m
    • 12 dives in the last 12 months, including at least 6 with a scientific task of work.
    • 20 dives in adverse conditions, such as currents, cold water, or moving water.
    • 20 dives as an in-water dive leader.

All evidence must be recorded in nationally acceptable logs, countersigned by suitably qualified persons. None of the above precludes the possible requirement for a practical or theoretical demonstration of any or all of the points shown.
