- Changes in
Sea Ice Volumes
- Isostatic Change
- When the sea levels change due to rising or sinking of land
- Local sea level change
- If land rises, sea level falls
- More water stored as ice on land will cause the land to sink and therefore the sea levels may appear to rise
- Eustatic Change
- Change in sea level due to volume of water
- Always a global effect
- As ice melts, the volume of water in the sea increases.
- Can also be caused through change in shape and size of an ocean basin
- Caused by tectonics.
- If the basin becomes larger the volume of the ocean will increase but the overall sea level will fall
- Isostatic Change
