The term "ice sheet" refers to ice over land, like the Greenland and Antarctic ice sheets. According to Google, an ice sheet is: "a permanent layer of ice covering an extensive tract of land, especially a polar region."
Ice over water is typically referred to as "ice cover" or "sea ice."
I have read that the Arctic sea ice is supposed to be completely melted in the summer before 2050. I haven't read when it is likely to disappear altogether all year long -- if at all.
The ice sheets will likely take centuries to melt completely. If we curtail our carbon emissions quickly enough, the East Antarctic ice sheet (which contains the vast majority of the ice) likely won't melt completely.
I doubt we will get our emissions down quickly enough to save the Greenland and West Antarctic ice sheets in the long run. And combined, they will ultimately add about 12 meters to the sea level.
