Geochemical stratigraphic data for phosphatised and unphosphatised samples of Fe-Mn crusts, Tropic Seamount, Northeast Atlantic Ocean (NERC Grant NE/M011151/1)

The data set presents major and trace element geochemical data obtained from ICP-MS measurements on micro-drilled subsamples of ferromanganese (Fe-Mn) crusts from Tropic Seamount, north-east Atlantic Ocean. The data represent detailed stratigraphic analysis of Fe-Mn crust samples 078_019 and 085_004. These samples were collected at 3100 and 1100 meters beneath sea level, respectively, during the JC142 expedition of the RRS James Cook for the MarineE-Tech project in 2016.
