Tide gauges installed along coastlines, or on ocean platforms, rely on sensors to make a continuous record of water height, by the minute, hour, or day. These records are made in comparison to a reference point known as the geoid, or mean (average) sea level and its imagined extension over land areas.
This source accounts for about 10% of all the water that enters this highly productive farmland, including rivers and rain.
A new study sheds light on the connections between climate change, glacier melt, sea level and the role of humans.
What can hidden motions underground tell us about earthquakes, eruptions, and even climate change? NASA scientists are using data gathered 400 miles above Earth to find out.
Researcher Manuela Girotto uses satellite measurements and computer models to improve estimates of an often overlooked contributor to sea level rise: water flowing from land.
Members of the NASA Sea Level Change Team met in Savannah, Georgia, to get a firsthand look at the effects of rising seas and to strengthen connections with the community.
