It is the responsibility of each scientific diver to maintain their fitness and proficiency as a diver.

Current Dive Physical

Frequency: An OSU Medical Evaluation and Medical History is required within the preceding 5 years (3 years if over the age of 40, 2 years if over the age of 60) from the last diving medical evaluation.  Following any major injury or illness, medical clearance to return to diving must be obtained from a physician. Please refer to the OSU dive medical evaluaton instructions and contact the OSU DSO if you have any questions concerning your fitness to dive.

Dive Logs

All research dives are to be logged into the Online Dive Log or e-mailed to within one month of dives.  A standardized Dive Log Template is available for divers not using the online log. During any 12-month period, each certified scientific diver shall log a minimum of 12 dives.

Depth Certification 

At least one dive to the depth of certification shall be made during each six-month period. Information about how to increase your current depth certification can be found on the Depth Certification page.

CPR, First-Aid & Oxygen Administration

Certifications are to be kept current. The length of certification depends on training agency standards. Most courses of these types require recertification every two years.


All life-support equipment shall be regularly examined by the diver. Regulators (1st & 2nd Stage), alternate air sources, hoses, gauges, computers, drysuits, and BCs are to be inspected and tested at 12 month intervals and overhauled if required. SCUBA cylinders must be hydrostatically tested in accordance with DOT standards, and a visual inspection performed annually.  An equipment inspection form should be completed by a certified repair technician and submitted to the Diving Safety Office annually.

Dive Plans

An OSU Dive Plan must initially be filed with the DSO and approved by the DCB for all scientific diving projects.

Oregon State University Scientific Diver Classifications

    Scientific Diver: Diver meets 100 hour training criteria, including dive number and bottom-time requirements. A checkout dive may be required if not previously completed at the time of classification as a Trainee or via reciprocity from another research diving program.

    Scientific Diver-in-Training: A newly trained scientific diver who has not yet completed the required scientific dives and bottom times. Individuals qualified at the Trainee level must dive with an active OSU scientific diver at all times.

    Visiting Diver: Diver certified through reciprocity from another scientific diving program.  Any visiting Scientific Diver may be asked by the OSU DCB to demonstrate their knowledge and skills for the planned dive.

Oregon State University Scientific Diver Status

    Active: Diver has current medical examination with no contraindications for diving; has current certification in First Aid, Oxygen Provider, and CPR; equipment records are current; and diver has met the 12 dives per year standard.

    Restricted: Diver has one or more non-medical deficiencies, (i.e., CPR / O2 provider is not current, equipment not inspected within 12 months or diver has not maintained the 12 divers per year activity level) but is otherwise qualified to dive according to standards of the OSU Diving Safety Manual. The OSU Diving Control Board has the authority to grant a waiver for specific requirements of training, examinations, depth certification, and minimum activity to maintain certification for any OSU diver. It is intended that in most cases the waiver is temporary to allow the diver to continue diving while correcting the deficiency. Restrictions are applied on a case by case basis by the DCB and may include temporary revocation of lead diver status, the requirement to dive only under the supervision of another OSU Active Scientific Diver, or a requirement to use OSU dive program-maintained equipment as appropriate.

    Inactive: Diver has let medical examination expire and/or has not maintained minimum dive frequency of 12 dives per year for over a year. It is assumed that an inactive diver is no longer involved in research that includes diving. Reconsideration for active dive status requires contacting the Diving Safety Officer (DSO), updating your records and may require refresher training and/or a skills/academic evaluation.
