Definition:
The early Holocene Sea Rise period (or EHSLR) is when the Earth underwent warming and meltwater release during the period between 11,650 and 7000 years ago, and consequently the volume of sea water increased. The sea levels rose from some 125 meters below the contemporary level to 2 meter above it, and then dropped to the present level. The coastlines moved inland and most contemporary islands, both large and small, were isolated off their mainlands.
