1. A Scientific Diving Officer (SDO) is primarily responsible for which
function within a scientific diving program?
A. Conducting only recreational dive training for students
B. Managing diving safety, compliance, training, and operational oversight
C. Replacing all research scientists during underwater projects
D. Approving commercial diving contracts exclusively
Answer: B. Managing diving safety, compliance, training, and operational
oversight
The Scientific Diving Officer oversees the scientific diving program by
ensuring safe operations, regulatory compliance, diver qualification,
training standards, and risk management procedures are properly
implemented.
2. Which organization is commonly associated with establishing scientific
diving standards in the United States?
,A. Federal Aviation Administration
B. Occupational Safety and Health Administration only
C. American Academy of Underwater Sciences
D. International Maritime Organization only
Answer: C. American Academy of Underwater Sciences
The American Academy of Underwater Sciences (AAUS) develops
consensus standards for scientific diving programs and provides guidance
for institutional scientific diving safety practices.
3. The primary purpose of a scientific diving manual is to:
A. Replace all diver judgment during operations
B. Document policies, procedures, and safety requirements
C. Eliminate the need for diver training
D. Permit unlimited diving without supervision
Answer: B. Document policies, procedures, and safety requirements
A scientific diving manual establishes institutional requirements,
operational procedures, emergency protocols, and administrative controls
that guide safe scientific diving activities.
4. Before approving a scientific dive plan, an SDO should first evaluate:
A. The diver’s personal preferences
B. The scientific importance only
C. Hazards, risks, resources, and emergency procedures
D. The underwater visibility forecast alone
Answer: C. Hazards, risks, resources, and emergency procedures
A proper dive plan requires comprehensive risk assessment, including
environmental hazards, diver capabilities, equipment needs, and
emergency response preparation.
, 5. The buddy system in scientific diving primarily exists to:
A. Increase underwater communication speed only
B. Provide mutual assistance and emergency support
C. Reduce the need for equipment checks
D. Allow divers to exceed training limits
Answer: B. Provide mutual assistance and emergency support
The buddy system improves diver safety by ensuring another trained
person is available to assist during equipment problems, emergencies, or
unexpected conditions.
6. A scientific diver should never exceed operational limits established
by:
A. Personal experience alone
B. The dive plan and institutional policies
C. Weather reports only
D. Research objectives only
Answer: B. The dive plan and institutional policies
Scientific diving operations must remain within approved limits because
safety requirements take priority over research goals or individual
confidence.
7. The main objective of a pre-dive briefing is to:
A. Eliminate the need for underwater communication
B. Review procedures, hazards, responsibilities, and emergency actions
C. Replace formal training programs
D. Determine scientific results before diving
Answer: B. Review procedures, hazards, responsibilities, and emergency
actions
, A pre-dive briefing ensures all team members understand the mission,
risks, communication methods, and emergency procedures before entering
the water.
8. Which factor most directly affects nitrogen absorption during a dive?
A. Diver’s eye color
B. Water temperature only
C. Depth and exposure time
D. Research equipment type
Answer: C. Depth and exposure time
Nitrogen absorption increases with greater pressure exposure and longer
bottom times, which is why depth and duration are central factors in dive
planning.
9. The purpose of decompression tables and dive computers is to:
A. Measure underwater visibility
B. Monitor nitrogen exposure and decompression requirements
C. Replace emergency training
D. Increase swimming speed
Answer: B. Monitor nitrogen exposure and decompression requirements
Dive tables and computers help divers manage nitrogen loading and
reduce the likelihood of decompression illness by controlling ascent
procedures.
10. A scientific diving program should maintain diver medical
evaluations because:
A. Medical fitness influences diving safety
B. Research requires medical publications
C. Divers cannot perform scientific tasks otherwise
D. It replaces dive training
