Life in the deep: All aboard the JOIDES Resolution

The JOIDES Resolution (pictured 2017) is one of the scientific community's only available drilling vessels. A 41-year-old converted oil exploration ship, her drill string can reach depths in excess of 8,000 meters below the ocean surface.

A drill string and reentry cone breaks the surface in Iceberg Alley off Antarctica in 2019. The drill string drops through a moon pool and the reentry cone eventually sits on the ocean floor. Each hole is given a name (in this case, U1536E), and the reentry cone allows for future expeditions to drill in the same hole.

Scientists on Expedition 378 are briefed on the various drill bits used by the ship. The two larger drill bits are rotary, cutting a donut shape. Some are made of carbon steel while others are impregnated with diamonds, said Brad Clement, director of science services at the IODP.
