Method for Extracting Tidal and Inertial Motion from ARGOS Ice Buoys Applied to the Barents Sea during CEAREX.
A harmonic analysis of tidal and inertial action was applied to observations of position of ARGOS buoys deployed on drifting multiyear sea ice in the Eastern Arctic-Barents Sea during CEAREX (1988-89). An ARGOS positioning-data screening protocol was developed and constructed using a constrained lea...

A harmonic analysis of tidal and inertial action was applied to observations of position of ARGOS buoys deployed on drifting multiyear sea ice in the Eastern Arctic-Barents Sea during CEAREX (1988-89). An ARGOS positioning-data screening protocol was developed and constructed using a constrained least squares algorithm for separate estimation of tidal and inertial currents. The analysis provided estimates of individual tidal components at 15-day intervals along the sea ice buoy drift tracks. The technique shows a reasonable qualitative distinction in current components at nearby semi-diurnal frequencies. Estimates of errors due to sampling and collinearity are derived directly from model statistics. Estimates of velocity produced from the unequally time-based data are then used for interpolation to a regular time grid for spectral analysis.
