Matt Carter is the leading technical diving maritime archaeologist in Australasia and is passionate about furthering the links between academic archaeological research and the technical diving community to explore shipwrecks outside of recreational diving limits..   Matt presented of the events in 1942, during the the War in the Pacific, when Sydney Harbour was attacked by waves of top-secret Japanese Midget Submarines. This ambitious attack shattered Australia’s illusion of safety and came just metres from altering the course of the war, leaving controversy and mystery in its wake. Using cutting-edge 3D photogrammetry and technical computer animation the team can now tell the true story of what really happened that fateful night using the wreck of the M-24 Midget Submarine as evidence.   See the team's stunning 3D model of the sub here https://sketchfab.com/3d-models/m-24-japanese-midget-submarine-australia-530a6b95263c4622ae7bedf4dd2e1089  The attack as detailed at Heritage NSW https://www.heritage.nsw.gov.au/about-our-heritage/feature-wreck-m24-midget-submarine/ Matt's Major Projects Foundation https://majorprojects.org.au  This episode on the OzdiveShow website  https://ozdiveshow.com.au/News-Details?newsId=41&title=6-Dr-Matt-Carter-explains-the-1942-Japanese-Midget-Submarine-attack-on-Sydney-Harbour  Dan Carlin's EXCELLENT mega pods about the battle between Japan and the allies in the Pacific is called 'Supernova in the East' Don't miss it https://podcasts.apple.com/ca/podcast/dan-carlins-hardcore-history/id173001861

We turn the GNARL Factor up to 11 on this one ! Deborah Johnston has been exploring and documenting caves all around Australia and New Zealand with the Sydney University Speleological Society (SUSS) for 12yrs. She is passionate about finding, documenting and sharing new cave discoveries - both above and below water. Her passion for cave exploration was recognised by leading Australian divers who mentored her so she could continue her research underwater by sump diving; where getting equipment to the dives within the caves often involves hours of backbreaking caving, climbing, crawling, squeezing and abseiling through mud with heavy bags of dive gear just to reach the waters edge. Deborah's main cave diving interest has been at the famous and ancient Jenolan Caves (the worlds oldest dated cave system) which is home to a long history of incredible diving feats spanning from the 1950s to present day. It is here Deborah and her team of 'SUSS' divers have made many significant discoveries by working together on monthly exploration trips.  Sump dives are harsh, deep and technical, little-to-no visibility, with sharp and unstable rock, and tight restrictions; all requiring creative gear configurations and meticulous planning to succeed. These techniques and configurations are practiced and maintained using deep wreck diving in the ocean as a training ground to prepare for project cave dives. Deborah is a member of the Explorers Club and NSW Cave Rescue Squad. Her Slug Lake Exploration Project has received funding from the Australian Geographic Society.

In this World Premiere episode, Emily Turton presents the fascinating and tragic history of the HMS Royal Oak which was torpedoed and sunk in Scapa Flow by a German U-Boat during World War II. The ship sunk rapidly taking 834 souls down with her in a massive blow to the British.   Emily is a technical diver, dive boat skipper and lecturer in Maritime Studies based in Orkney - a group of islands off the top of Scotland. She can usually be found aboard her purpose-built dive boat MV Huskyan. Emily has dedicated the last 15 years to the wrecks of Scapa Flow and continues to champion the WWI German Fleet Wrecks. The driving force behind the Scapa 100 Initiative, a project set up to commemorate the centenary of the scuttling of the WWI German High Seas Fleet, Emily also organised the HMS Hampshire 100 and HMS Vanguard 100 surveys in 2016 and 2017 respectively. In her survey and project work, Emily collaborates with a wide group of people and institutions building expert teams of likeminded individuals. Digital heritage is at the forefront of their work which uses underwater photography, videography and 3D photogrammetry to document shipwrecks and bring them to the surface for the wider community to see. Emily was inducted as a Fellow in the Explorers Club in October 2018.

Diving with the isolator valve closed, breathing from the wrong tank, taking in a mouthful of caustic cocktail, these are the sorts of tech diving incident reports which DAN collects and publishes. DAN also assists tech divers with decompression sickness, coordinates evacuations, and researches tech diving fatalities to identify potential issues that may need resolving. In this episode Peter highlights some of the cases divers have filed with DAN ... and asks us to remember them for our own diving safety.
