Unparalleled views of sea level rise ⬆️🌊🛰

Global sea levels have risen more than 4 inches (102 millimeters) since measurements began in 1992, increasing coastal flooding in some places.

As ocean water warms, it expands and takes up more space. The added heat in the air and ocean is also melting ice sheets and glaciers, which adds freshwater to the ocean and further raises sea levels. 

The Surface Water and Ocean Topography (SWOT) mission, launched in 2022, and Sentinel 6 Michael Frelich, launched in 2020, are providing unparalleled views of sea level rise on top of decades of data from other missions.

Image Description: The video shows a 21-day average of sea surface height anomalies highlighting ocean eddies and currents as imaged by the Surface Water and Ocean Topography (SWOT) satellite. The red and orange colors indicate where the sea surface was higher than normal and the blues are where it was lower than normal. The higher resolution provided by SWOT will give scientists unprecedented views of sea level rise globally.
