Effects of Rising Ocean Levels Does sea floor lower as water rises?

As I recall parts of the North American continent have been 'rebounding' since the retreat of glaciers from the last ice age. As sea levels rise can we expect the ocean floor to sink due to the additional pressure caused by so much more water over it? If so would the sinking ocean floor in any meaningful way mitigate the risks due to rising sea levels? If the sea floor sinks would that result in any kind of corresponding lift of land not covered by ocean?

As I could understand it, if the sea levels will rise islets and islands will be covered by water. I learned that for some 100,000 years from now, some countries will be covered by water and it is like a water world. Rising of sea floor might result from the pressure and some new islands may emerge from it. But I don't think that it is enough to compensate for the rising of sea levels.

As global warming increases the sea level also increase for example more melting of ice increase more level of water which take more space in the earth and the level of sea increses in earth.
