Did you ever consider that maybe it's supposed to? Cold fresh water from the land ice ends up capping salt water.

Changes to sea surface temperaturesAs the glaciers and ice shelves melt on the Antarctic continent, freshwater is added to the oceans. This layer of cold, fresh water on the ocean surface freezes easily [10]. When combined with increased ocean stratification due to this enhanced run off [11], sea-surface temperatures are depressed, encouraging sea-ice formation.

A recent modelling study has shown that increases in fresh meltwater flux from melting glaciers and ice caps on Antarctica under various IPCC standardised global warming scenarios offsets the decline in sea-ice area and to even further encourage the increases in sea-ice extent, especially in winter (in summer, air temperatures are too high to support significant sea-ice growth) [12].

Increased stratification has further implications. Suppression of ocean circulation overturning decreases the ocean heat flux available to melt ice, leading to an increase in net ice production[13].
