Production, dissolution, accumulation, and potential export of biogenic silica in a Sargasso Sea mode-water eddy
Production dissolution accumulation
2014/4/16
Rates of biogenic silica (bSiO2) production, dissolution, accumulation, and potential bSiO2 export were
determined in a Sargasso Sea mode-water eddy (MWE) during two occupations in April 2007. Standi...
Application of Empirical Mode Energy to the Analysis of Fluctuating Signals
empirical mode decomposition energy feature extraction fluctuant signal analysis
2011/9/9
After an aerial object enters the water, physical changes to sounds in the water caused by the accompanying bubbles are quite complex. As a result, traditional signal analyzing methods cannot identify...
The asymptotic field of mode I quasi-static crack growth on the interface between a rigid and a pressure-sensitive material
pressure-sensitive material mode I quasi-static interface crack crack-tip field asymptotic analysis
2011/9/13
A mechanical model of the quasi-static interface of a mode I crack between a rigid and a pressure-sensitive viscoelastic material was established to investigate the mechanical characteristic of ship-b...
An Experimental Study of the Resonant Instability of an Internal Wave of Mode 3 Over a Range of Driving Frequencies
Resonant Instability Internal Wave Driving Frequencies
2009/3/26
An experimental study of the stability of a progressive internal wave of mode 3 propagating down a long tank filled with a linearly stratified salt solution is conducted over the range 0.45ω3/N0.80, w...
IGPP and AOML bottom pressure measurements at four MODE stations constitute a unique set of deep-sea tidal measurements (although deployed for other purposes). A response analysis relative to a Bermud...
Pressure fluctuations on the deep seafloor at frequencies below inertial and tidal have been measured. Between 0.1 and 1 cycle per day the variance is about 2 mb2, spectra diminish with increasing fre...
MODE：IGPP Measurements of Bottom Pressure and Temperature
IGPP Measurements Bottom Pressure Temperature
2009/3/24
We review the MODE deployment of IGPP bottom instruments, together with preliminary tests on the Pacific seafloor and in the laboratory. Pressure and temperature were measured with quartz-crystal tran...
Measuring Dynamic Heights with Inverted Echo Sounders：Results from MODE
Inverted Echo Sounders Measuring Dynamic Heights Results from MODE
2009/3/7
Inverted Echo Sounders (IES) were deployed during MODE at seven ocean bottom stations to acoustically monitor depth variations of the main thermocline. The IES transmits pulses of 10 kHZ sound and rec...
Horizontal Divergence and Vorticity Estimates from Velocity and Temperature Measurements in the MODE Region
Horizontal Divergence MODE Region Vorticity Estimates
2009/3/7
Estimates of horizontal derivatives of velocity made by differencing velocity measurements are used to show that the observed velocity field due to low-frequency mesoscale motions during the prelimina...
Available Potential Energy for MODE Eddies
Available, potential energy gravitational potential energy MODE Eddies
2009/2/9
Available, potential energy (APE) is defined as the difference between total potential plus internal energy of a fluid in a gravity field and a corresponding reference field in which the fluid is redi...
The Subpolar Mode Water of the North Atlantic Ocean
Subpolar Mode Water North Atlantic Ocean
2009/2/8
The warm waters of the subtropical and subpolar basins of the North Atlantic have tight regional temperature-salinity relationships, and are conventionally called the regional “Central Waters.” A volu...
Cross-Gyre Ventilation of the Subtropical Gyre：An Internal Mode in the Ventilated Thermocline
Cross-Gyre Ventilation Ventilated Thermocline Subtropical Gyre
2009/1/20
A model of cross-gyre geostrophic flow is presented. It is a two-layer model of the (Northern Hemisphere) subtropical thermocline above a resting lower ocean. The northern boundary of the gyre is take...
On the Potential Vorticity Structure of Weakly Ventialted Isopycnals：A Theory of Subtropical Mode Water Maintenance
Potential Vorticity Structure Weakly Ventialted Isopycnals Subtropical Mode Water Maintenance
2009/1/12
A two-layer model of the general circulation including wind and thermal forcing is discussed. The flow in each layer is geostrophic, hydrostatic and obeys linear potential vorticity constraints. The e...
Numerical solutions are examined for nearly axisymmetric geopotential monopole vortices whose vertical structure is essentially confined to the lowest few vertical modes. The vortex environment is a r...
Quasi-homogeneous layers in vertical profiles of temperature and salinity in the eastern North Atlantic near Madeira indicate the existence of a subtropical Mode Water in the Eastern Basin. Temperatur...
