At the end of this month, we will be running an update of our free Massive Open Online Course ("MOOC") about "Exploring Our Oceans", intended for anyone interested in finding out more about our watery world, with no previous background in science required. One topic we'll look at in Week 1 of the course, "A hidden landscape", is how we map the ocean floor, and how much has been mapped at different levels of detail. Continue reading →

Onwards and downwards: when ROVs or AUVs are lost in ocean exploration

To link with Week 5 of our free Massive Open Online Course on "Exploring Our Oceans", during which we focus on how we explore the oceans, this post takes a look at some of the ROVs and AUVs that have been lost during ocean exploration.

MINING AT DEEP-SEA VENTS: WHAT ARE THE IMPACTS ON MARINE LIFE?

Deep-sea hydrothermal vents are one of the seafloor environments now being targeted for mining of their mineral resources, because the "chimneys" that form at vents are particularly rich in metals such as copper that we need for modern technology. Continue reading →

SHEDDING SOME LIGHT ON THE INTERNATIONAL SEABED AUTHORITY

In my previous post, I outlined some of the possible impacts of mining at deep-sea vents on marine life, and how effective regulation at a regional scale will be essential to reduce risks of habitat loss and potential species extinction. Continue reading →
