sea levels
Marine surface elevations
Sea levels refers to multiple measurements of the ocean's surface height, typically across different locations or time periods.
The phrase appears most often in discussions of climate change, where rising sea levels threaten coastal areas: Sea levels have risen significantly over the past century.
The singular sea level is the standard reference point for measuring elevation on land.
