A ferromanganese-coated cobble more than 10 centimeters (4 inches) in diameter was collected during Dive 16 of the 2021 North Atlantic Stepping Stones expedition. We also collected many smaller ferromanganese nodules and sediment using the remotely operated vehicle’s suction sampler. The size and distribution of the nodules remained similar throughout the length of the ferromanganese nodule field traversed during the dive..
