That is a shame,my condolences to the family and friends as well.
Most folks are probably aware of the way the ice survivalist say is a good way to get back up.I'll paste it here
for the folks not famiiar with it.I'm thinking a frog kick could also de a dolphin kick,where you thrust both legs at
the same time,like a mermaid.
This comes from an Ice Rescue Specialist.To assess what is required to get out in this situation, we cut a hole in the ice and jumped in with rope and a dry suit on. By far the easiest way to get out is with ice picks, ice awls, bear claws or whatever you call them. If you don't have them, don't panic and act fast. Swim to the edge of the good ice, put your forearms on the ice, get your body near horizontal and with powerful frog kicks you can push yourself out. You should lift with your arms, but only straight up. This will help you get over the ice edge as you kick. Don't try to pull yourself out with your arms, they will only slip off. The idea is to keep yourself low and use the frog kick to push yourself onto the ice. Once out, get to shore or help quickly and out of your wet clothing as soon as possible.
