Marine Critical Minerals: Collected Sample Information

As part of our efforts to expand the science and understanding of marine critical minerals, NOAA Ocean Exploration and partners continue to leverage capabilities to conduct mapping and exploration operations, including within areas of the U.S. Exclusive Economic Zone identified as high priorities for polymetallic nodules. This page includes preliminary information about samples collected during projects and expeditions being led or supported by NOAA Ocean Exploration; please refer to the final data repository listed for each project for final quality controlled and approved sample information.
