Warming temperatures causes ocean water to expand, which raises sea level and glacial ice to melt that creates water that makes its way into ocean basins.

Finally, narwhals scan vertically as they dive, which could help them find patches of open water where they can surface and breathe amid sea ice cover.

This water pump can be put out of action or weakened by changes in the freshwater pressure, the ice sheet breaking up or shifting sea ice and this results in the increasing climatic variability.

They play an important role in the formation of new sea ice and deep water.

The fall of the temperature of the sea water is sometimes a sign of the proximity of ice, although in regions where there is an intermixture of cold and warm currents going on, as at the junction of the Labrador Current and the Gulf Stream, the temperature of the sea has been known to rise as the ice is approached.

Most sea - level rise comes from water and ice moving from land into the ocean, but the melting of floating ice causes a small amount of sea - level rise, too.

During ice ages, which are mainly driven by rhythmic variations in Earth's orbit and spin that alter sunlight in the Northern Hemisphere, growing ice caps and glaciers trap so much frozen water on land that sea levels can drop a hundred meters or more.
