Definition 27.6 High School Earth and Space Sciences · 第 27 章 — Reading Past Climates

The Last Glacial Maximum is the time, about $23\,000$ to $19\,000$ years ago, when the ice sheets of the last glacial period were at their largest.

South-East Asia with the sea 130\, m lower than today. Green: land today; tan: the floor that a sea level 130\, m lower uncovers; blue: sea. The present relief is used, so the coastline is only approximate. Computed from the ETOPO1 relief (NOAA), every 0.1 degree. — South-East Asia with the sea $130\,\mathrm{m}$ lower than today.
