We have become acquainted with an under-ice dive team. The hut on the left contains the hole where the divers descend. The hut on the right is where the self-propelled camera goes down. It's steered by a person inside the hut.
This is the hole that the divers use. Looks chilly, doesn't it. The ice here is 20 feet thick. The water below is 28 degrees F.
These divers are Stacy, who heads the team, and Francois.
Stacy puts on her flippers. Her suit is a "dry suit." Under it are two layers of long underwear.
They get ready to descend.
Stacy jumps in.
This is the picture the camera gives us of what the divers see. The square is the wire frame in front of the camera that protects it when it bumps the bottom of the ocean. The divers like this water because it is very clear--no algae.
The camera is steered by a person above the ice. I got to drive it! What the camera sees is projected onto a screen in the hut.
