A close look at a geological sample collected during Dive 01 of the 2021 North Atlantic Stepping Stones expedition. The remotely operated vehicle team was able to break off a piece of the frequently observed ferromanganese crust, which is visible as a black band in this image. Analyses of this sample will provide scientists with information such as mineral composition and age of the crust, water chemistry, and past water circulation patterns.
