FIGURE 7.1 Illustration of relative sea level rise since the last ice age: 26,000 years ago, sea level is estimated to have been about 400 feet (120 meters) lower than it is today. This curve was assembled using analyses of coral reefs all over the world. The abbreviation MWP refers to various meltwater pulses, which caused sea level to rise relatively rapidly. MWP-1AO, ~19,000 years ago; MWP-1A, ~14,600 to 13,500 years ago; MWP-1B, ~11,500 to 11,000 years ago; MWP-1C, ~8,200 to 7,600 years ago. SOURCE: Gornitz (2009).
