By using the COADS (Comprehensive Ocean-Atmosphere Data Set) data, we have examined sea-surface temperature (SST). Although the region of analyses is limited, we may give the following conclusion : the SST in the mid latitudes of the Pacific and Atlantic Ocean abruptly increased around 1940; and they are rather larger than those in the other area, i. e. the high latitudes and eastern Atlantic Ocean, even though the SST in the central and eastern Pacific Ocean is deduced from the other investigators' results. Taking account of ROLL's result and our estimate of the random error, we may infer that the increase of SST is real, in spite of contamination of the effect due to the change of observing method, i. e. the "bucket method" or the "intake method".
