2015/9/7
We report on the installation of a long-term buried ocean-floor broadband seismic station
(MOBB) in Monterey Bay, California (USA), 40km off-shore, at a water depth of 1000 m.
The station was instal...
Seafloor Observatory Science: a Review
multidisciplinary seafloor observatories marine science and technology
2015/9/7
The ocean exerts a pervasive influence on Earths environment. It is therefore important that we learn how this system operates (NRC, 1998b; 1999). For example, the ocean is an important regulator of c...
