So, why have 31 scientists and 90 operation staff, technicians, ships crew and drillers travelled from around the world to get on board a boat in Auckland, New Zealand to sail into the middle of nowhere? To study the Louisville Seamount Trail of course!

When I first learned that the Earth’s magnetic poles change direction over time I was fascinated. The concept that magnetic north becomes magnetic south, and then the poles flip again and again every several thousand years really blew my mind. The Earth’s magnetic field is generated in the molten outer core as metallic minerals convect around the solid inner core.

Paleomagnetism is the study of the Earth’s ancient magnetic field. Such studies have helped lead to important discoveries like seafloor spreading and plate tectonics. Here on the JOIDES Resolution during Expedition 354, one of the main uses of this tool is to find out the age of sediments from the Bengal submarine fan. So how do we actually do that?

We've all played with magnets before, but no one knows magnetism like the Paleomag team aboard the JOIDES Resolution. Shipboard paleomagnetists provide paleomagnetic and rock-magnetic measurements of recovered rocks.
