Ferromanganese crusts were collected via dredge from seamounts within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and major and trace element geochemical and x-ray diffraction mineralogy analyses. Geochemical and mineralogy data, bulk and layer thickness information, as well as location information (latitude, longitude, depth) for each ferromanganese crust sample are provided here. These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the global ocean.
