ANALYSIS OF ICE BOTTOM TOPOGRAPHY ON OKHOTSK SEA COAST OF HOKKAIDO- OBSERVATION RESULTS IN 2004-

We have conducted sea ice surveys using Ice Profiling Sonar (IPS) and Acoustic Doppler Current Profiler (ADCP). This paper reports on the quantitative analysis results on the sea ice data, especially on ice bottom topography, obtained in 2004. and the renewed knowledge obtained by comparing the data...

From results of analysis of the sea ice bottom topography (draft profile) with non-stationary characteristics by the locally stationary AR model, we were able to make the assumption that although the average power (variance of draft depth) of each subinterval (span) considered locally stationary was different, the normalized spectra of the subintervals were identical, which indicated similar results as the previous data.
