Ridge 2000 is an interdisciplinary initiative to study Earth's oceanic spreading ridge system as an integrated whole, from its inception in the mantle to its manifestations in the biosphere and water column. The Ridge 2000 program is sponsored by the National Science Foundation.

The Ridge 2000 Special Issue of Oceanography magazine is now available online.
