The land ice of the Antarctic landmass (Glaciers, Ice Shelves) are calving, cracking, and breaking apart into large chunks of ice at an accelerating rate along the Antarctic coastline of the Southern Ocean due to warming temperatures. These large chunks of land ice (which are freshwater ice) then float and drift in the Southern Ocean. As these freshwater ice chunks drift and float farther and farther away from the Antarctic landmass into the other Oceans (Atlantic, Pacific, Indian, etc) they melt further into regular liquid water and then they finally turn from freshwater into regular saltwater of the seas. So this melting land ice which becomes sea ice which becomes liquid water contributes to the rising ocean levels aroung the world. Furthermore the Arctic is losing sea ice in the Arctic Ocean at 3x the rate that Antarctic is gaining sea ice along its Southern Ocean shoreline, Please read these two NASA articles, look at this NASA graph, and watch this NASA YouTube video that discusses the detailed nuances surrounding this particular phenomena. If you have any questions after looking at the information please feel free to ask me.
