Economic Considerations in the Design of Ocean Observing Systems
Economic Considerations Ocean Observing Systems
2015/7/3
Recent work on the potential economic value of improved coastal ocean observing capabilities suggests that aggregate values of better ocean observing system information for all US waters could be in t...
Mooring Truncation Design of a Deepwater SPAR
SPAR mooring system truncation global response
2011/9/9
To solve the dimensional limitations of physical models in tests, an equivalent water depth truncated design for a classical SPAR working in 913 m water was investigated. The water depth was reduced t...
