 Yeah, so you take a torch and it's essentially similar to a night dive because you've got this lid plus the sunlight is at such a low level because it's not hit above the horizon yet that you've just got very little light making its way into the water column. You've painted such a vivid picture that I'm kind of stress clenching my fists. That sounds like such a nightmare. I'd be absolutely terrified. What's it like in there?
