Sinead Farrell co-authored a paper on a new mean dynamic topography of the Arctic Ocean published in Geophysical Research Letters, January 6. The manuscript was one of the five most popular GRL downloads for the week of January 17, 2012. The study, led by Farrell and co-authored by investigators from NOAA, NASA, and University College London, derives the highest resolution mapping of the Arctic Ocean mean sea surface possible constructed using 5.5 years of ICESat laser altimetry and contemporaneous Envisat radar altimetry. A new mapping of Arctic Ocean mean dynamic topography for the period 2003-2009 was derived using the satellite-only data and reveals the major features of Arctic Ocean dynamical height are consistent with in suite observations.
