Air–Sea Heat Flux Measurements from Nearly Neutrally Buoyant Floats
Publisher: American Meteorological Society
Abstract: The ability of neutrally buoyant, high-drag floats to measure the air?sea heat flux from within the turbulent oceanic boundary layer is investigated using float data from four different winter and fall float deployments. ...
Estimation of Velocity from Argos-tracked Surface Drifters during OCEAN STORMS
Publisher: American Meteorological Society
Abstract: Modern surface drifters tracked by Argos are an attractive method for measuring the spatial structure of near-surface currents. This note discusses the accuracy to which velocity can be estimated from such data, assuming ...
Upper-Ocean Inertial Currents Forced by a Strong Storm. Part II: Modeling
Publisher: American Meteorological Society
Abstract: The evolution of near-inertial frequency currents is often thought to be controlled by the linear, inviscid equations of motion. This hypothesis is tested by simulating the near-inertial currents described in Part I using ...
Upper-Ocean Inertial Currents Forced by a Strong Storm. Part III: Interaction of Inertial Currents and Mesoscale Eddies
Publisher: American Meteorological Society
Abstract: The interaction of strong near-inertial frequency currents generated by a storm with preexisting subinertial frequency currents is investigated. For 10 days after the storm, the near-inertial currents remain in the mixed ...
Turbulent Vertical Kinetic Energy in the Ocean Mixed Layer
Publisher: American Meteorological Society
Abstract: Vertical velocities in the ocean boundary layer were measured for two weeks at an open ocean, wintertime site using neutrally buoyant floats. Simultaneous measurements of the surface meteorology and surface waves showed a ...
Surface Wave Measurements from Subsurface Floats
Publisher: American Meteorological Society
Abstract: ressure gradient measurements on a subsurface Lagrangian float are used to measure the spectrum of surface waves for 100 days of measurements at Ocean Weather Station Papa. Along Lagrangian trajectories of surface waves, ...
The Ocean Boundary Layer below Hurricane Dennis
Publisher: American Meteorological Society
Abstract: Three neutrally buoyant floats were air deployed ahead of Hurricane Dennis on 28 August 1999. These floats were designed to accurately follow three-dimensional water trajectories and measure pressure (i.e., their own depth) ...
Absorption of Internal Waves by the Benthic Boundary Layer
Publisher: American Meteorological Society
Abstract: The interaction of near-inertial velocities with the benthic boundary layer above a flat bottom is investigated using a diagnostic model and a 3-month time series of velocity from a fixed array of current meters. The ...
Velocity Structure of the Benthic Ocean
Publisher: American Meteorological Society
Abstract: Velocity measurements in the outer part of the bottom boundary layer on the Hatteras Abyssal Plain are examined for indicators of boundary-layer turbulence. Velocity fluctuations in two frequency bands, near-inertial and ...
The Energy Flux from the Wind to Near-Inertial Motions in the Surface Mixed Layer
Publisher: American Meteorological Society
Abstract: Time series of wind stress computed from long-term meteorological buoy data off North America are used to examine the forcing of surface inertial currents by the wind. A simple damped slab model of the mixed layer is used ...
