Seasonal Isotherm Depth Climatology for the Eastern Tropical Pacific

摘要

A seasonal climatology of the depths of the 10C, 15C, and 20C isotherms in the eastern tropical Pacific is presented. The analyses used Kriging, which is a method for optimal interpolation of data fields. The data set consisted of 10,505 expendable bathythermograph (XBT) and conductivity-temperature-depth (CTD) stations collected during non-El Nino years. Results are presented on shaded contour maps with values overprinted at 2 degree intervals. The method of analysis also yields an estimate of the uncertainty of each interpolated point.
