Turbulence, Acoustic Backscatter, and Pelagic Nekton in Monterey Bay
Publisher: American Meteorological Society
Abstract: During August 2006 aggregations of nekton, most likely small fish, intersected microstructure survey lines in Monterey Bay, California, providing an opportunity to examine biologically generated mixing. Some aggregations ...
Intense, Variable Mixing near the Head of Monterey Submarine Canyon
Publisher: American Meteorological Society
Abstract: A microstructure survey near the head of Monterey Submarine Canyon, the first in a canyon, confirmed earlier inferences that coastal submarine canyons are sites of intense mixing. The data collected during two weeks in ...
The Role of Upstream Waves and a Downstream Density Pool in the Growth of Lee Waves: Stratified Flow over the Knight Inlet Sill
Publisher: American Meteorological Society
Abstract: Observations and modeling simulations are presented that illustrate the importance of a density contrast and the upstream response to the time dependence of stratified flow over the Knight Inlet sill. Repeated sections of ...
Tidally Generated Turbulence over the Knight Inlet Sill
Publisher: American Meteorological Society
Abstract: Very high turbulent dissipation rates (above ε = 10?4 W kg?1) were observed in the nonlinear internal lee waves that form each tide over a sill in Knight Inlet, British Columbia. This turbulence was due to both shear ...
Persistent Near-Diurnal Internal Waves Observed above a Site of M2 Barotropic-to-Baroclinic Conversion
Publisher: American Meteorological Society
Abstract: Near-diurnal internal waves were observed in velocity and shear measurements from a shipboard survey along a 35-km section of the Kaena Ridge, northwest of Oahu. Individual waves with upward phase propagation could be ...
Dynamic Response Calibration of Sea-Bird Temperature and Conductivity Probes
Publisher: American Meteorological Society
Abstract: Dynamic response calibrations have been made for temperature and conductivity probes produced by Sea- Bird Electronics. These probes are used on wire-lowered and towed conductivity, temperature, and depth systems (CTDs) ...
Observations of Near-Inertial Internal Gravity Waves Radiating from a Frontal Jet
Publisher: American Meteorological Society
Abstract: hipboard ADCP and towed CTD measurements are presented of a near-inertial internal gravity wave radiating away from a zonal jet associated with the Subtropical Front in the North Pacific. Three-dimensional spatial surveys ...
High-Frequency Internal Waves at 0°, 140°W and Their Possible Relationship to Deep-Cycle Turbulence
Publisher: American Meteorological Society
Abstract: An analysis of a moored time series at 0°, 140°W from November to December 1991 found a nighttime enhancement of isotherm displacement variance and of zonal velocity variance below the surface mixed layer at frequencies ...
Upper Ocean Shear and Density Variability at the Equator during TROPIC HEAT
Publisher: American Meteorological Society
Abstract: A four and one-half day time series of upper-ocean shear and density observations was collected in the tropical Pacific Ocean in November 1984. The measurements were made on the equator at 139°50?W during a period when the ...
Patterns of Shear and Turbulence across the Florida Current
Publisher: American Meteorological Society
Abstract: Measurements by the Multi-Scale Profiler (MSP) at seven stations spanning the Straits of Florida characterize levels and patterns of internal wave activity and mixing in this vertically sheared environment. Contrasting ...
