FAQ

How do I get “CAUS certified?”

CAUS does not certify divers, and there is no such thing as “CAUS certification.” CAUS develops and maintains the Standard of Practice for Scientific Diving, which details competency, training and operational requirements for CAUS members. Scientific diver training is conducted by CAUS member organizations. Check the Member Organizations page for a list of current CAUS members in good standing.

What are the different Scientific Diver categories?

CAUS member organizations can provide training that will allow scientific divers to attain several different ratings (for details, see Standard of Practice for Scientific Diving, 3.2):

  • Scientific Diver in-Training – must meet basic entry requirements (3.2.1 – 2), must dive with Scientific Diver I, II or DSO, must not dive deeper than 20m, must dive during daylight hours and must not dive in hazardous conditions or use special modes or equipment.
  • Scientific Diver I – must meet all requirements of Scientific Diver-in-Training, must have accumulated 25 logged dives and 15 hours bottom time including planning and executing one dive to 20m under the direct supervision of the DSO and three others under the direct supervision of the DSO or other Scientific Diver I or II. A Scientific Diver I is limited to a depth of 20m.
  • Scientific Diver II – must be a Scientific Diver I, must be registered for an approved project that required diving between 20m-40m, must complete an exam on the physics and physiology of deeper diving with a grade of at least 75%, and must plan and execute 4 dives deeper than 20m and up to 40m, with at least one to 40m under the direct supervision of the DSO, and demonstrate proficiency in various areas applicable to deeper diving. A Scientific Diver II is limited to a depth of 40m.
  • Scientific Aquarium Diver – must meet basic entry requirements (3.2.1 – 2), must accumulate 12 logged aquarium dives and 8 hours bottom time. A Scientific Aquarium Diver is limited to diving solely in an aquarium (see 3.2.3.4 for definition and details).
