Evidence of a 4–6 Day Barotropic, Planetary Oscillation of the Pacific Ocean
Publisher: American Meteorological Society
Abstract: Spectral analysis of scattered island and coastal tide-gage records from the Pacific Ocean reveals the presence of a coherent sea level fluctuation at 4?6 days period. The oscillation is distinct from baroclinic, inertia-gravity ...
Tidal Charts of the Central Pacific Ocean
Publisher: American Meteorological Society
Abstract: New co-amplitude and cotidal charts of the central Pacific Ocean have been constructed for constituents M2, S2, N2, K1 and O1. The charts exhibit some significant differences from previous attempts. Admittance curves, ...
On a Simple Empirical Parameterization of Topography-Catalyzed Diapycnal Mixing in the Abyssal Ocean
Publisher: American Meteorological Society
Abstract: The global spatial distribution of the turbulent diapycnal diffusivity in the abyssal ocean is reexamined in light of the growing body of microstructure data revealing bottom-intensified turbulent mixing in regions of rough ...
Estimating Mooring Motion when the Pressure Sensors Fail: A Method Employing Inverted Echo Sounders
Publisher: American Meteorological Society
Abstract: In the presence of a strong current, such as the Gulf Stream or the North Atlantic Current, current meter moorings are known to ?blow over? due to drag from the moving water. This dipping of the current meters, which has ...
Eddy Energetics in the Upper Equatorial Pacific during the Hawaii-to-Tahiti Shuttle Experiment
Publisher: American Meteorological Society
Abstract: Eddy energetics in the central equatorial Pacific Ocean is examined using Acoustic Doppler Current Profiler velocities and CTD densities collected during the Hawaii-to-Tahiti Shuttle Experiment, in 1979?80. Three distinct ...
Correction of Motional Electric Field Measurements for Galvanic Distortion
Publisher: American Meteorological Society
Abstract: Interactions between motional electric fields and lateral gradients in electrical conductivity (e.g., seafloor topography) produce boundary electric charges and galvanic (i.e., noninductive) secondary electric fields that ...
The Fortnightly and Monthly Tides: Resonant Rossby Waves or Nearly Equilibrium Gravity Waves?
Publisher: American Meteorological Society
Abstract: The fortnightly and monthly tides are discussed in the light of recent sea level observations and numerical modeling results. Within the tide gauge network of the low-latitude Pacific, the fortnightly tide is shown to ...
Observations of the Boundary Current System at 26.5°N in the Subtropical North Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Five current meter moorings and four horizontal electric field records spanning June 1990?February 1992 are used to describe the mean structure and variability of the vertically averaged velocity field and volume transport ...
Observations of 20-Day Period Meridional Current Oscillations in the Upper Ocean along the Pacific Equator
Publisher: American Meteorological Society
Abstract: Prominent oscillations of the meridional current, with a mean period of approximately 20 days, have been observed in the upper ocean over several years from May 1979 to October 1985 using moored current measurements along ...
Subinertial Frequency Response of Wind-Driven Currents in the Mixed layer Measured by Drifting Buoys in the Midlatitude North Pacific
Publisher: American Meteorological Society
Abstract: Previous analyses of satellite-tracked drifting buoy data (30 m drogue depth) and Fleet Numerical Ocean Center (FNOC) surface wind stress in the midlatitude North Pacific during autumn/winter have shown near-surface current ...
