We carried out two immersions with the ROV and two dives with the divers, covering the west, north and southeast coasts of the islands, so we’ve seen a variety of seabeds today. It’s a shame, though, that the dives with the ROV have been shorter than planned -we usually go for 3 hours- and we had to take it out of the water because we found an abandoned net in front of us, hooked on to a rock. If the ROV gets tangled in the net, we may not be able to disentangle it and, at these depths, we risk losing the ROV altogether. That is why nets, lines, ropes, anchorages, traps, etc. that we frequently find abandoned along the way are a threat to both the film crew (ROV and divers) and the environment in which they are found.
The abandoned traps, for example, still capture animals that die inside of them, unable to escape. The ropes and lines act like guillotines for everything that crosses their path, because the currents move them, “decapitating” corals, gorgonians, sponges, etc. and nothing can grow in their radius of action. The same goes for the nets, which continue to trap animals for years after they've been abandoned.
