Abstract
The objective analysis (OA) method is adapted in order to map the Gulf Stream thermal front, and resulting output maps are verified against independent data. This extension of the OA method involves removing the mean field and normalizing the variance prior to performing the objective analysis; both of these fields are restored afterward. In this way, the mapped field decays to an appropriate mean field far away from the measurement sites, and the statistics of the normalized perturbation field are homogeneous, as is required by the OA method. We test the sensitivity of the adapted OA method to variations in four control parameters: mean field, correlation function, standard deviation field, and input sampling interval. -from Authors
