We lowered the submersible camera into the water. There's sea life down there. Fish, mainly. The camera came with a 50-metre cable, which wasn't nearly long enough. It looks like the crater widens as it goes down, and the camera quickly lost sight of the edges. The crater didn't look like this the last time I saw it. Before, it was a pretty much a tube; now, it looks like the entrance to an underground ocean. We've requested a specialist in geology: we need to make sure this whole area isn't going to collapse. It's funny to think that the old station was there for all that time without anyone realising that the ground underneath was slowly eroding.
We started rigging up a longer cable for the camera, and a stronger light source. There was even talk of getting some kind of bathysphere. It'll have to wait until tomorrow, though. Currently, the worst storm I've ever seen in this region is raging above our tents. Everyone is huddled together, and you can barely see six inches ahead if you venture out. I hope it lets up. It'll be hard to sleep in this maelstrom.
