The seafloor remains one of the least explored areas on Earth.  Join us for a deep dive, to understand the science needed to advance our understanding and help to find the mineral resources that may well be needed by society in the future.

We get the overview on both the history and the future from Mark Hannington, University of Ottawa, Canada.  From the collaboration involved in studying black smokers and their relationship to what we know about volcanogenic massive sulfide deposits, to the new frontiers of the continental shelf and beyond – there is a lot of greenfield exploration to happen in the ocean.  How can we begin to understand the potential, without a geologic map? Perhaps what is needed is a Geological Survey of the Ocean.

Our second guest, Meg Stewart, Mount Royal University Calgary, Alberta, Canada tackles the seafloor geologic mapping question.  As a post-doctoral fellow with Mark Hannington she took on the mapping of the Lau Basin, home to numerous hydrothermal vents and, as they discovered,  complicated tectonic processes with implications for our understanding of earth systems.

Lastly, we address the potential for polymetallic nodules to provide metals needed for the green transition.  Samantha Smith, Blue Globe Solutions, has dedicated sixteen years to helping guide the science needed to exploit seabed resources responsibly and gives us her insights and wisdom.
