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. This is why ocean going research is fundamental, not only for seabed mapping, ...[Read More]

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. Hydrothermal vents are places where tectonic activity provides a way for the h ...[Read More]

Marine plastic is just one of the many challenges facing the future of our oceans. For many years researchers have been attempting to understand this problem, but it can be surprising to learn how many things are still unknown, even in oceans we may think of as being familiar. The Mediterranean Sea is one such place, where this photograph was taken by David Jones just off the coast of Malta. ...[Read More]
