Oceanographer Amy Gartman joined two members of the U.S. State Department at the 24th session of the International Seabed Authority, the organization charged with implementing the Convention on the Law of the Sea, an international treaty governing use of the oceans and their resources.

The U.S., which has not signed the convention, attends ISA sessions as an observer. The ISA Council met March 5–9 to further develop regulations for exploiting mineral resources on the international seabed—an area underlying much of the world’s oceans. As science advisor, Gartman helps the U.S. delegates understand the nature and locations of different types of seafloor mineral deposits, and what environmental protections might be needed if they are mined. Gartman succeeds USGS research geologist Jim Hein, a deep-ocean minerals expert who attended ISA sessions from 2000 to 2016 and still advises the State Department.
