However the presence of salt in seawater changes all of this. Whilst the freezing point of freshwater is 0° C, the salt forces the freezing point of seawater to be lower (see the blue line in Figure 1). Typically seawater with a salinity, or salt content, of 35 parts per thousand (or 3.5%) will have a freezing point of around … See more Sea ice consists of blocks of frozen seawater known as "floes", which are always in motion pushed along by winds and ocean currents. Sea ice floes range in size between 10 m and 5 km wide and are of the order of 0.5 to 5 … See more Sea ice cover varies seasonally with a maximum cover occurring during early spring and a minimum cover during early autumn. This seasonality is caused by the amount of sunlight reaching the polar regions of the Earth … See more Arctic sea ice motion is restricted by the geometry of the Arctic Ocean and the prevailing wind and currents.
