of a dive manager.
+_)(*()
What's the initial limited depth for a sports diver? - ANSWER: 20m
What's the progressively extended depth of a sports diver? - ANSWER: 35m
Is a neap tide small or large? - ANSWER: Small
Is a spring tide small or large? - ANSWER: Large
What causes a neap tide? - ANSWER: When the Moon is at a right angle to Earth and the Sun,
creating the least amount of gravitational pull in one direction, creating weak tides.
What causes spring tides? - ANSWER: The gravity of the sun and moon pull in the same
direction, creating strong tides.
Neap tides coincide with what? - ANSWER: The quarters of the moon
Spring tides coincide with what? - ANSWER: New and full moon
What's the average tide cycle in most places? - ANSWER: 12 hours
How many tide cycles in a day? - ANSWER: 2
How many high tides in a day? - ANSWER: 2
How many low tides are there in a day? - ANSWER: 2
How many times do spring tides occur in a lunar month? - ANSWER: 2
How many times do neap tides occur in a lunar month? - ANSWER: 2
What's the tidal range? - ANSWER: High water - low water
What's slack water? - ANSWER: At the tides turning point, when the water speed is at its
slowest.
What can make diving on a static site (e.g. a wreck) safer? - ANSWER: Diving in slack water
What is ground swell? - ANSWER: When wind causing wave action on the surface can be felt
on the sea bed.
When is ground swell the roughest? - ANSWER: When the surface winds go against the
tide/stream/current flow.
Is an incoming or outgoing tide better for visibility? - ANSWER: Incoming
What are five factors that can affect visibility? - ANSWER: - bad weather

- tides
- being close to river estuaries
- lots of phytoplankton + zooplankton (most likely to be a problem in spring in most places.)
-disturbance by divers. +_)(*()
What's a thermocline? - ANSWER: Sudden change in temperature, may look oily/ shiny and
produce a change in visibility
What can you do to reduce the effect of glare on the surface (as a boat crew member, not a
diver?) - ANSWER: - wear polarised sunglasses
- position the boat with the sun behind you
What are four things you should take into account when doing a risk assessment? - ANSWER:
Conditions, depth, breathing gas and equipment
As neoprene wetsuits compress, there is a loss of what? - ANSWER: Thermal insulation
What precautions can you take to minimise the risk of a dive to yourself and your buddy? -
ANSWER: -don't dive if you're unsure
- service equipment
- back up supply of gas
- pre agreed narcosis check (at agreed depth or gas level)
- practiced rescue skills
-
What are the four practised rescue skills you'll do as a sports diver? - ANSWER: CBL/AS, basic
life support (BLS), rescue breathing (RB), chest compressions (CC)
What's the in water life support sequence? (6) - ANSWER: - make bouyant
- shout for help
- extend airway
- give 1 minute RB's
- tow to shore or RB while waiting for boat
- de-kit and land/recover
What does IPO stand for? - ANSWER: Immersion Pulmonary Oedema
What can IPO be confused with? - ANSWER: Drowning, as both involve fluid in the lungs.
What's the difference between IPO and pulmonary oedema? - ANSWER: IPO = PO but when in
water
What is IPO? - ANSWER: Fluid going from alveolar capillaries into the sacs, as compression of
the legs forces blood to collect in the chest.
What are risk factors for IPO? - ANSWER: High blood pressure, strenuous exercise, excessive
hydration.
What are signs of IPO? - ANSWER: Breathing difficulties (even when on the surface, not
undergoing strenuous exercise) , confusion e.g signalling out of air when it's fine, or a belief that
