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.
NASA Sea Level Change Team member Robert Kopp uses data on past sea-level rise to improve forecasts of what's to come – and to help coastal planners prepare.
The researchers shared their latest findings, and discussed how to make sea-level science more useful to planners and others preparing for changes on the U.S. coast.
To better predict changes in Antarctica's Thwaites Glacier, sea-level scientists turn their focus to the bedrock beneath.
The Surface Water and Ocean Topography mission will explore how the ocean absorbs atmospheric heat and carbon, moderating global temperatures and climate change.
In a question and answer session, ice sheet researcher Sophie Nowicki, a member of the NASA Sea Level Change Team, discusses a new era in sea-level research.
