| | | | | | | | | | | |
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
| | | | | | | | | |
