2023年6月2日 · The Last Ice Age: Low Seas, Exposed Landmasses. During an ice age, sea levels fall as ocean water that evaporates is stored on land on a large scale (ice sheets, ice caps, glaciers) instead of returning to the ocean.

This map depicts the Earth during the last ice age, specifically the Late Glacial Maximum (roughly 14,000 BCE) when the climate began to warm substantially. With so much of the planet's water tied up in ice, global sea level was more than 400 feet lower than it is today.

2025年1月28日 · Map of the maximum extent of the ice during the last ice age, around 20 000 years ago. Note in particular the extensive lakes ponded behind the ice, fed by the north flowing rivers. Note also the increased size of the Caspian and …

Ice Age Mapper leverages recent advances in interactive mapping and data visualization to effectively communicate ecological trends through space and time. By promoting map sharing via permanent unique URLs Ice Age Mapper is designed for both research and teaching use.

2017年6月7日 · This map shows how the coastlines of the world may have appeared during the Last Glacial Maximum, around 21,000 years ago, when sea levels were approximately 125 meters (410 feet) below present. This map doesn't include any of the large paleolakes of the time period, it's intended to mainly just show extra land and the different coastlines.

2018年6月8日 · During the last ice age glaciers covered almost one-third of Earth's land mass, with the result being that the oceans were about 400 feet (122 meters) lower than today. During the last global "warm spell," about 125,000 years ago, the seas were about 18 feet (5.5. meters) higher than they are now.

In an interactive article titled “If All the Ice Melted,” National Geographic invites you to “Explore the world’s new coastlines if sea level rises 216 feet. The maps here show the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it 216 feet and creating new shorelines for ...

New Zealand’s coastline in the ice age Next In the last major glacial period some 20,000 years ago, New Zealand’s land area was much larger, as the sea was 120–30 metres lower than its present level.

Between 18,000 and about 6000 years ago, most of the ice melted off of Canada and Scandinavia, causing sea level to rise, flooding the rims of all the dry lands.
