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
