Expedition

Cave diving is often described as one of the most dangerous kinds of exploration. I'm trained to master my control under water to avoid kicking up silt and to carry backups of every piece of vital equipment. In mapped caves, we follow a prelaid line to avoid getting lost, but when we explore new caves, we have to take our own with us, and it is literally our lifeline. I do need to prepare that guideline because when we measure the cave, you can't get a line knotted at the market, supermarket, already. We have to do that all the time before we go diving. -

From Robbie's experience of the geology in this area, we're expecting to have to get through squeezes, passageways barely big enough for a person to pass through. Having to do this myself fills me with utter dread. As far as my job is concerned of being in charge of safety generally speaking on this expedition, there is nothing, absolutely nothing I can do as soon as they leave they leave the surface. They pretty much are on their own. There is no rescue in there and the worst-case scenario is body recovery. There is no half measures really. Yeah, it's pretty scary. -

We don't know if it's a very easy dive, what we're going to do, we don't know what we find, it's exploration, right? My main concern is that if I die tomorrow, my last meal will have been a pot noodle. -

Nobody's going to die tomorrow. Cheers to that. - Cheers. To the dive. - Cheers. Cheers to that, cheers to that, safe dive, safe journey and safe return.
