Measuring Dynamic Heights with Inverted Echo Sounders: Results from MODE
Publisher: American Meteorological Society
Abstract: 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 records the time τ for ...
A Simple Method for Measuring Deep Convection
Publisher: American Meteorological Society
Abstract: The glass-pipe technology used for RAFOS floats is applied to the monitoring of convection in deep mixed layers. The velocity of a vertical current is estimated from the relationship between the drag force exerted on a ...
Heat Transport into the North Atlantic Ocean North of 32°N Latitude
Publisher: American Meteorological Society
Abstract: Direct velocity and temperature measurements obtained on a bimonthly basis from September 1980 to May 1983 in the Gulf Stream at 73°W longitude were used in combination with historical hydrographic and current meter data ...
Early Swedish Contribution to Oceanography: Nils Gissler (1715–71) and the Inverted Barometer Effect
Publisher: American Meteorological Society
Abstract: Nils Gissler (1715?71) was a remarkable Swedish scientist and physician who appears to be the first to describe the inverted barometer effect, based on joint observations of sea level and atmospheric pressure at Härnösand, ...
A Study of Velocity Profiles Through the Main Thermocline
Publisher: American Meteorological Society
Abstract: A time series of velocity profiles derived from three methods are used to describe the variations of current in time and in the vertical. Absolute velocity profiles were Obtained by acoustically tracking a falling probe; ...
Towards a Lagrangian Description of the Gulf Stream
Publisher: American Meteorological Society
Abstract: Downstream velocity relative to the axis of the Gulf Stream is examined through the use of data from SOFAR floats. The speed calculated from the position of the floats along constant pressure surfaces is expressed in terms ...
Wavenumber Spectrum in the Gulf Stream from Shipboard ADCP Observations and Comparison with Altimetry Measurements
Publisher: American Meteorological Society
Abstract: The wavenumber spectra for velocity and temperature in the Gulf Stream region are calculated from a decade (1994?2004) of shipboard acoustic Doppler current profiler (ADCP) measurements taken as part of the Oleander Project. ...
An Acoustic Telemetry System Implemented for Real-Time Monitoring of the Gulf Stream with Inverted Echo Sounders
Publisher: American Meteorological Society
Abstract: From August 1989 until August 1990, a simple acoustic telemetry system was used for obtaining real-time data from four inverted echo sounders (IESs) deployed in the Synoptic Ocean Prediction Experiment (SYNOP) inlet array ...
The Structure, Dynamics, and Origin of a Small-Scale Lens of Water in the Western North Atlantic Thermocline
Publisher: American Meteorological Society
Abstract: A small-scale, isolated, anticyclonically rotating lens of water was observed in the western North Atlantic thermocline during the POLYMODE Local Dynamics Experiment. Using a combination of SOFAR float, hydrographic, ...
