Hadal-Lander was constructed and used in a sequence in Episode 2 (The Deep) of the documentary Blue Planet II. The Hadal-Lander is seen descending into a CG model of a subduction trench, alongside some footage obtained during Hades-K and Hades-M. He was a guest presenter at New Scientist Live at the ExCel London centre in September 2017 [n38] where he also joined BBC World Service's Science in Action live panel show with Roland Pease. He presented at Ocean TEDx KingsPark on 1 December 2021, and took the audience into the deepest ocean where few humans who have dived, including 11 km down in the Mariana Trench. In 2022 he led an expedition to the Diamantina Fracture Zone in the East Indian Ocean where his team discovered the deepest fish off mainland Australia at a depth of 6177 metres. His zoological author abbreviation is Jamieson. He has co-authored the description of 12 new species. The Five Deeps Expedition In 2018, undersea explorer Victor Vescovo selected Jamieson to be the Chief Scientist on the Five Deeps Expedition, whose objective was to thoroughly map and visit the deepest point of all five of the world's oceans by the end of September 2019 in a two-person full ocean depth submersible. Jamieson joined the expedition on the DSSV Pressure Drop in July 2018 and oversaw 103 deep-sea lander deployments spanning the Abaco Canyon, offshore Bahamas, Grand Banks, Puerto Rico Trench and the Agulhas Fracture Zone in the Atlantic Ocean, the South Sandwich Trench in the Southern Ocean, the Diamantina Fracture Zone and Java Trench in the Indian Ocean, the Mariana Trench, San Cristobal Trench, Santa Cruz Trench and Tonga Trench in the Pacific Ocean, and the Molloy Hole in the Arctic Ocean. During the expedition he descended to a depth of 7180m in the Java Trench, and then to 10,710m in Sirena Deep in the Mariana Trench, 7200m in the Puerto Rico Trench and 2000m in the Arctic with Vescovo. The first of these dives made him the first British citizen to reach hadal depths, and the second of these dives, made him the 8th deepest diving human in history. Jamieson rejoined the DSSV Pressure Drop in February 2020 for Caladan Phase I Expedition to the wreck site of La Minerve. In March 2020 he was Chief Scientific on the Phase III expedition to the deepest point of the Red Sea (Suakin Trough), where Jamieson
