Abstract:

A method and system for detecting the location of an airsea interface on an Instrumented Tow Cable ITC when distributed temperature measurements are provided. The airsea interface is determined by estimating the variance of observed temperature in the proximity of each measurement cell. The method and system described herein uses a sliding variance across the entire cable length. The variance of the cell or cells in the area of the interface has been found to be large compared to other cells. Accordingly, the location of the airsea interface is determined based on the location of the peak variance. The location of the airsea interface is used in determining the catenary of the ITC.
