Here we see the dive crew cutting holes in the 45cm sea ice and then going in for a dive to collect scientific samples to help with learning about global climate change. To see more Antarctic film blogs check out 'Kirk Watson' channel.
Interesting use of a chainsaw to cut ice. The chainsaw has to be stripped and fully rebuilt after each time we use it for a day so the salt water doesn't destroy it:)
