Definition
- The NeMO Project was conceived as a long-term study of the interactions between geology, chemistry, and biology on a dynamic part of the mid-ocean ridge system, using state-of the art technology. The goal is to make multiple observations at one location over several years to document changes in interrelated systems. Hence, the need for a multi-year seafloor observatory. The site chosen for this observatory effort is called "Axial Seamount". Axial is an active volcano located on the Juan de Fuca Ridge, about 250 miles off the coast of Oregon and Washington. The Juan de Fuca Ridge is a boundary where two of the Earth's tectonic plates move slowly, but episodically, apart. When the plates move, the process is accompanied by small earthquakes and, at some times, by magma intrusions and volcanic eruptions.Axial volcano is seamount at 460N, 1300W, at the intersection of the Juan de Fuca Ridge and the Cobb seamount chain. It rises 1100 m above the surrounding ocean floor to a minimum depth of 1400 m below sea level. The Axial volcano was chosen for the NeMO Project because it is the most volcanically active site on the Juan de Fuca Ridge. The NeMO Project also is an opportunity to share this exciting scientific research with teachers, students, and the general public. The NeMO cruise will have a teacher at sea this summer and another teacher working onshore to help make research results available via the web. Daily updates are planned for the calendar page describing life at sea and scientific results during the expedition as well as answers to your questions during the cruise.
