NASA Sea-Level Change Team: From Observation to Actionable Information

Brought to you by the COPRI Coastal Engineering Sciences Committee
Chair - Christopher Bender, Ph.D., P.E., D.CE, M.ASCE

Presenter: Dr. Benjamin Hamlington
Dr. Benjamin Hamlington


Dr. Ben Hamlington is a Research Scientist in the Sea Level and Ice Group at the NASA Jet Propulsion Laboratory. He studies global and regional sea-level changes with a particular focus on using satellite observations to understand sea level variability on interannual to decadal timescales. He is also interested in how sea level responds to both natural and anthropogenic forcing, and what this will mean for coastal populations both now and in the future. This interest extends to bridging the gap between scientist and decision-makers, and the challenge of generating useful scientific information for planning purposes. Dr. Hamlington is the current team lead of the NASA Sea Level Change Science team, and a member of NASA's Ocean Surface Topography and GRACE/GRACE-FO science teams. He is also a member of the Interagency Sea Level Taskforce, USGCRP Coasts Group, and WCRP Grand Challenge on Sea Level.


The NASA Sea-Level Change Team (N-SLCT) was established in 2014 with the goal of improving the understanding of regional relative sea-level change on a range of timescales. The formation of this team was driven by the recognition that sea-level change results from a diverse set of physical processes that interact and combine in potentially complicated ways across a range of timescales. The N-SLCT relies heavily on NASA satellite observations in addition to reanalysis and modeling efforts to advance our understanding of sea-level change in the past, present, and future. 

Now in its third iteration, a common goal of the team is to create integrated forecasts of sea-level across a range of timescales. Beyond the science focus of the team, the N-SLCT has broadened its scope in order to address the growing societal need for better sea-level guidance. The N-SLCT has taken tangible steps to engage the stakeholder community and create partnerships with the goal of providing “useful” sea-level information that is founded in the improved scientific understanding established by the team.

Here, an overview of the extent of the work being done by the N-SLCT is provided by discussing how the team is supporting sea-level decision-making. Specifically, the talk is structured around the flow of information from science to eventual application, covering the work the N-SLCT is doing in the following areas: 1) Observation, 2) Modeling and Analysis, 3) Synthesis, 4) Research-to-Application.
