We Were Wrong About the Mariana Trench Abyss
Descend into the freezing abyss where time stands still and the laws of biology are broken. In this episode on Deep Sea Gigantism, we encounter the chilling Greenland Shark—a 400-year-old blind titan that has roamed the Arctic since the 17th century. From the crushing pressure of the Mariana Trench to the oxygen-rich polar seas, discover why creatures like the Bigfin Squid and Giant Isopods evolve into monstrous sizes to survive the eternal darkness. 📚 Expedition Logs Vessel: NOAA Ship Okeanos Explorer & E/V Nautilus Observation Methods: Deep-sea Hydrophones & ROV SuBastian Locations: Arctic Ocean (Polar Seas), Monterey Canyon, and Challenger Deep (Mariana Trench) Key Discovery: Biological evidence of extreme longevity and the "Oxygen Trap" theory causing gigantism.
