Sinéad Louise Farrell is an Assistant
Research Scientist at the Earth System Science Interdisciplinary Center
(ESSIC) at the University of Maryland, College Park, collaborating with
the NOAA Laboratory for Satellite Altimetry and the NASA Cryospheric
Sciences Branch. Dr. Farrell is affiliated with the Cooperative Institute
for Climate and Satellites (CICS), within ESSIC. She joined NOAA as a
National Research Council associate in 2007. Sinead studied at University
College London and received an M.Sci. in Earth and Space Science in 2002,
and a Ph.D. in 2007, for a dissertation on satellite laser altimetry over
Her main interests lie in remote sensing of the Earth's polar regions
using satellite and airborne altimetry for marine geophysics and cryospheric
investigations. Current research topics include the seasonal and inter-
annual variability of Arctic sea ice thickness and volume, the mean dynamic
topography and circulation of the Arctic Ocean, and the marine gravity field
of the Arctic Ocean. A major component of this research involves analyses
and cross-comparison of altimetry data from satellite missions including
ICESat, CryoSat-2, Envisat, and ERS-2, as well as aircraft missions such as
NASA's Operation IceBridge. Sinead currently serves as a member of the NASA ICESat-2 Science
Definition Team and the NASA Operation IceBridge Science Team.
