We know the topography of the moon better than the Earth’s seafloor, so we need to keep studying the ocean, and, for me, going to sea is the best way. Only twenty percent of the seafloor is already mapped (see the Seabed 2030 Project), leaving eighty percent of our ocean unmapped, unobserved, and unexplored.

650 metres below the chilly waves of the North Atlantic Arctic Ocean, equidistant between Norway, Iceland and Greenland, are the Jan Mayen Vent Fields. Home to a series of hydrothermal vents strung along a set of normal faults and fissures that run parallel to the seafloor ridge, this is a strange and fascinating place.
