Sea Level Change Science Team (ROSES 2019)

Rising seas are one of the most disruptive consequences of climate change, impacting highly-populated coastal communities through an increased occurrence and intensity of flooding events, storm surges, coastal erosion, salt-water intrusion, losses of biodiversity and freshwater resources. 1 Understanding the physical processes behind these changes is key to predicting the potential impact of rising seas and extreme events on coastal communities, the national and global economy, and is recognized as one of the Grand Challenges of our time by the World Climate Research Programme (WCRP).

To address this challenge, NASA has assembled a multi-disciplinary Sea Level Change Science Team (N-SLCT) consisting of leading experts in the fields of oceanography, geodesy, cryosphere, hydrology, modeling, statistics, and science communication. 2 Multiple NASA science programs have contributed to various aspects of this research including programs in Physical Oceanography, Cryospheric Sciences, Interdisciplinary Sciences, Earth Surface and Interior, and Earth Science Data and Information System (ESDIS). Since 2014, the N-SLCT has been conducting interdisciplinary sea level science by collecting and analyzing observational evidence of sea level change, quantifying the underlying causes and driving mechanisms, producing projections of future changes in sea level, as well as communicating NASA's latest discoveries to the public through NASA's Sea Level Portal at As a result, progress has been made on a number of important problems in sea level science, resulting in a better understanding of ice sheet dynamics, the development of tools and assessments of the impacts of mass loss from ice sheets and glaciers on coastal cities, and improved representation of vertical land motion related to coastal subsidence, tectonics, and Earth's post-glacial rebound.

The program is intended to integrate research results, data sets, and model outputs to improve the accuracy of sea level estimates and its components, to integrate results into better forecasts of sea level rise, and to communicate the results of NASA's sea level research in a simplified manner to the science community and the public.
