The temperature of the WSC is highly variable. It often depends on atmospheric conditions which are highly variable in their own right. In general, however, the warmest core temperature of the Atlantic Water in the WSC is around 2.75 °C near Svalbard to 2.25 °C near Franz Josef Land to 1.0 °C north of the new Siberian Islands. Salinity in this warm core is often greater than 34.95 psu. Ocean temperature values for the beginning of the WSC are typically between 6 and 8 °C with salinities between 35.1 and 35.3 psu.
