Drain the oceans and flood the land with this sea level simulator
Sliding Shores is a non-commercial interactive tool that allows users to visualize the effects of changing global sea levels on a 3D globe. By adjusting a slider, viewers can see coastlines retreat or submerge in real time, ranging from draining the oceans to flooding Mount Everest. The visualization aims to provide a tactile understanding of how thin the layer of habitable land is and how dramatically surface area ratios shift across geological time.
- ▪Sliding Shores is a personal, non-commercial science visualization created by Richard Franklin.
- ▪The tool uses the Etopo 2022 Global Relief Model to render Earth as a 3D globe with adjustable sea levels.
- ▪Users can set sea levels from -11,000 meters to +8,849 meters to observe real-time changes in coastlines.
- ▪The visualization includes presets for historical ice age levels and future scenarios like the 2100 worst case.
- ▪The tool does not account for local variables such as high tides, storm surges, or existing sea walls.

Drain the oceans and flood the land with this sea level simulator Rob Beschizza 5:26 pm Sun Sep 27, 2026 Boil off 100 feet and we get Doggerland back! You've surely seen interactive maps showing the effects of the sea level rising, but Sliding Shores makes a game of it: you get a beautifully-rendered globe and a slider to raise or lower the oceans. There's a load of presets, from "oceans drained" to "drown Everest," a feat not even Waterworld managed. Historical ones include the height of the ice age; more credibly ominous futures include "2100 worst case" and "West Antarctic collapse." It's the work of Richard Franklin . Sliding Shores is a personal, non-commercial science visualisation.
