Expedition Deep Ocean tells the inside story of this exploration of one of the most unforgiving and mysterious places on our planet, including the site of the Titanic wreck and the little-understood Hadal Zone. The expedition pushed technology to the limits, mapped hidden landscapes, discovered previously unknown life forms and began to piece together how life in the deep oceans affects our planet -- but it was far from easy.
