U.S. Geological Survey

USGS explains why the U.S. EEZ seafloor matters for critical minerals, and how little of it has been sampled.

USGS and partners analyzed 57 ferromanganese crusts across 30 degrees of Pacific latitude to map compositional controls.

USGS, BOEM and NOAA met for the first time to align their critical marine minerals plans, in Santa Cruz.

The 2019 federal critical minerals strategy tasks BOEM with evaluating offshore mineral potential in the U.S. EEZ.

USGS oceanographer Amy Gartman is building a research community around the chemistry of deep-sea mining impacts.

Amy Gartman joined the U.S. observer delegation to the ISA as science advisor on seafloor mineral deposits.

USGS geologists dredged the Rio Grande Rise off Brazil for iron and manganese crusts rich in cobalt and tellurium.

Arctic ferromanganese crusts are the only ones in the global ocean highly enriched in scandium, a USGS-led study found.

The International Marine Minerals Society gave its Moore Medal to USGS geologist James Hein for 43 years of work.

A Saint Petersburg State University doctoral student joined USGS in Santa Cruz to study Arctic ferromanganese crusts.
