The second programme in the series sees the team of explorers travelling through some of the most remote islands of Micronesia.
Kate Humble's scuba team encounter spectacular underwater wildlife while the extreme deep divers and scientists dive as deep as humans can without a submersible and continue to find fish that have never been seen before.
In this environment, even the most experienced member of the deep team is not immune to unexpected equipment failure.
