| 英文摘要 | In this study we examined the applicability of the threshold, curvature, maximum angle, and relative variance methods for identifying the oceanic bottom mixed layer (BML) thickness HBML. Using full- depth temperature profiles along 17 WOCE sections covering the Atlantic, Indian, and Pacific Oceans, we found that the BML thicknesses determined based on the threshold, curvature, and maximum angle methods had wider 95% confidence intervals and much lower quality indexes (QI, 0: 57) compared with those based on the visual inspection (QI50: 68). The relative variance method appeared to perform better than the other methods because the 95% confidence interval and QI (0.60) values were closer to those determined based on the visual inspection, although differences were still present. We then proposed an integrated method by optimizing the possibleHBML values obtained from the four methods. TheBMLthicknesses determined using the integrated method were closest to those based on the visual inspection according to the higher QI (0.64) and more stations (71%) with QI. 0: 5. Compared with the results in previous studies, the integrated method determined the consistent BML thicknesses in most regions (e. g., the northern Atlantic), and it also effectively identified the BML thicknesses in some regions where the BML was considered to be not readily detectable (e. g., the Madeira Abyssal Plain). |
