Expendable Bathythermograph XBT temperature depth profile data from 17 locations in the north Pacific Ocean has been analyzed to extract information concerning the thermal microstructure. The microstructure information is then examined to determine if the distribution can be associated with the climatic regions of the north Pacific Ocean proposed by Tully. A modified binomial filter used by Roden to analyze STD data was applied to find a mean temperature series. A temperature perturbation series results when the mean is subtracted from the original XBT series. Two resulting parameters, average mean temperature perturbation vertical thickness scale and average maximum amplitude of the temperature perturbations, can be associated with the microstructure. The average mean temperature perturbation vertical thickness scale was found to increase with latitude from 20 degrees N to 55 degrees N, and as the thickness scale increased, the maximum amplitude of the perturbations was found to decrease.
