At constant mass, the volume of the oceans, and thus sea level, will vary with changes in the density of sea-water. Density is inversely related to temperature. 3, record 2, English, - thermal%20expansion%20of%20oceans
Record number: 2, Textual support number: 1 OBS
Thus, as the oceans warm, density decreases and the oceans expand. In order to estimate oceanic expansion (past or future), changes in the interior temperature, salinity, and density of the oceans have to be considered, either empirically or by models. 3, record 2, English, - thermal%20expansion%20of%20oceans
