Dive with CCR in Water at -1°c

Francisco · 18th April 2008, 08:22

Hello,

Is it possible to dive into the water to -1 °, for example in Antarctica ?

The temperature is it a problem for dive with a CCR?

I have dived in -25C in air and water was around 2C without any issues on the rebreather.

seawater freezes at -21°C (0°F)... So.. up in the cold north where i live it often drops below 4°C near the surface in the winter when air temperature is -5 to -25°C...

Try -4 in salt water !
Keep unit out of the cold as long as possible pre breathe in the car or inside boat cabin , pre breathe at least 5mins , use 1st stages with cold kits, 80% alcohol kits work well. check lubricant specifications some go hard at minus , this makes o rings leak.
Cover screens with wooley sock, remove in water .
FFM mask nice or use goose/ duck fat around lips and exsposed skin.
Check manufactorers adivce on scrubber duration. carry two stages,of bailout gas.
This is what i learnt this winter on my sports kiss.
My coldest dive this year was 0 in water -50 with wind chill on surface.
This year in Norway the winter wasnt the coldest.
This is only what ive found so far, looking forward to learn more next year.

I have never Rebreather-dived in surface water colder than 0 °C with the water being at 1-2 °C during the dive itself so I dont know.

Sea water can get colder than -4°C particularly if its flowing or higher than usual in salt content.

I confirm that I dove at -1°C in Antarctica, but with a tank 12 L stainless. It's very cold!

You can see my report in Antarctica, but not with rebreather: Diving in Antarctica - ScubaBoard
