Whence comes the name “Escanaba”?
As the Escanaba Trough expedition wraps up, there remains one somewhat prosaic mystery: Why do we call this seafloor spreading center Escanaba Trough?
Critical Mineral Resources in the Escanaba Trough
In this seafloor spreading center are potential deposits of minerals deemed “critical” to national security and commerce

Deep Sea Exploration, Mapping and Characterization
Deep sea areas support unique ecosystems and are sources for energy and minerals. Exploring and mapping the oceans will help us fill gaps to better understand planetary-scale processes including tectonics and marine hazards; energy, mineral and biological resources; and other large-scale Earth systems. Improved knowledge of the deep sea will help us sustainably manage and use ocean resources.
