Wind picked up strongly and the wave crests became foamy on the afternoon of February 27, 1995. The JOIDES Resolution steamed at full speed up the West African coast, heading northward for the Canary ...
The NOAA Ship Okeanos Explorer:New Ways For Exploring the Ocean
NOAA Ship Okeanos Explorer New Ways Exploring the Ocean
2015/7/7
Since its inception in 2001 in response to the report of the President's Panel on Ocean Exploration (McNutt et al., 2000), the Ocean Exploration Program of NOAA's Office of Ocean Exploration and Resea...
Applications of GODAE Ocean Current Forecasts to Search and Rescue and Ship Routing
GODAE Ocean Current Search and Rescue
2015/7/6
As GODAE ocean forecast systems progress, their contributions toward improving the safety and efficiency of operations at sea will increase. In this article, we review present uses of GODAE ocean fore...
Queensland marine biologists have found that the damage sustained to a Filipino coral reef from an American warship is more extensive than first thought.
Analysis of Properties of Thrust Bearing in Ship Propulsion System
thrust bearing thrust pad lubrication properties ship propulsion shaft geometrical factors
2011/9/9
Thrust bearing is a key component of the propulsion system of a ship. It transfers the propulsive forces from the propeller to the ship’s hull, allowing the propeller to push the ship ahead. The perfo...
Research on the dynamic performance of ship isolator systems that use magnetorheological dampers
magnetorheological fluid damper vibration reduction shock resistance isolator
2011/9/13
Isolator systems on ships should ideally be able to simultaneously reduce low frequency vibration response and high frequency shock response. Conventional isolator systems are unable to do so. To solv...
Application of a compound controller based on fuzzy control and support vector machine to ship’s boiler-turbine coordinated control system
ship boiler-turbine coordinated system support vector machine inverse control compound control
2011/9/9
Multivariables, strong coupling, nonlinearity, and large delays characterize the boiler-turbine coordinated control systems for ship power equipment. To better deal with these conditions, a compound c...
Further Studies of a Cold Eddy on the Eastern Side of the Gulf Stream Using Satellite Data and Ship Data
Gulf Stream Satellite Data Cold Eddy Ship Data
2009/2/23
A cold eddy was observed in late March and early April 1975 to encounter the eastern boundary of the Gulf Stream and entrain warm Gulf Stream water into its outer fringes. Available evidence indicated...
Average Seasonal Variation of the Atlantic Equatorial Currents from Historical Ship Drifts
South Equatorial Current Seasonal Variation Historical Ship Drifts
2009/1/20
Surface currents in the tropical Atlantic were studied using historical ship-drift data. These are the only available data capable of resolving the long-term seasonal fluctuations of currents over a b...
Ocean Circulation Model Hindcasts of the 1982-83 El Niño：Thermal Variability along the Ship-of-Opportunity Tracks
