Sea Level Study
Sentinel-6 Michael Freilich, a joint U.S.-European satellite built to measure global sea surface height, has sent back its first measurements of sea level. The data provide information on sea surface height, wave height, and wind speed off the southern tip of Africa.
“We’re excited for Sentinel-6 Michael Freilich to begin its critical work studying sea level and helping us understand the many aspects of our planet’s global ocean,” said Thomas Zurbuchen, NASA’s associate administrator for science at the agency’s headquarters in Washington. “I know Mike would be thrilled that the satellite bearing his name has begun operating, but he’d also be looking forward to studying the data from this important mission, as we all are.”Read the rest of this entry »

There are two primary causes of global mean sea level rise – added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica’s ice sheet is currently responsible for 20-25 percent of global sea level rise.
But how much of a role will it play hundreds of years in the future?
- “Understanding Sea Level,” a summary of decades of scientific research that has shaped our knowledge of sea level rise: its causes, including a warming, expanding ocean and melting ice on land; projections of future sea level rise; and ways in which humanity might adapt, largely drawn from NASA data.
- An interactive data analysis tool, launching in mid-2016, that will allow direct access to NASA datasets on sea level. Users will be able to manipulate these datasets to automatically generate charts, graphs and maps of sea surface height, temperature and other factors. The analysis tool will also allow users to make forecasts of future conditions, as well as “hindcasts” — retroactive calculations of past trends and conditions.
- News highlights and feature stories with strong visual elements that explore the findings of sea level researchers in detail.
- An extensive library of published papers on sea level-related topics, hyperlinked to individual citations throughout “Understanding Sea Level.”
- A multimedia section with dynamic still and video imagery, and a glossary of sea level terms.
- A “frequently asked questions” section maintained by sea level scientists. Users can submit questions to scientists and data managers.
