National Underwater Marine Agency

The National Underwater Marine Agency is an independent federal agency of the United States government, responsible for oceanography research. NUMA is the undersea counterpart of NASA, the space agency.

NUMA's oceanography research includes marine archaeology, the study of sea life, deep-sea geology and mining, and observations of the effects the oceans have on the climate of the earth - as well as carrying out secret work for the government from time to time.

Its headquarters building is a thirty-story tubular structure covered in green reflective glass situated overlooking the Potomac River in eastern Washington, D.C..
