A method has been developed to monitor the surface velocity field by combining repeated acoustic Doppler current profiler (ADCP) observations and satellite altimetry data. The geostrophic velocity anomaly is calculated from the sea surface height anomaly field estimated from the altimetry data by an optimal interpolation. It has been confirmed that this accurately observes the smoothed velocity...
Arctic sea surface height variability and change from satellite radar altimetry and GRACE, 2003-2014
Introduction: For the majority of the Cassini Mission, Titan’s hydrocarbon lakes and seas were observed to be quiescent and remarkably calm, with vertical deviations of less than a millimeter[1,2,3,4,5]. This lack of observable surface roughness has been attributed to a seasonal effect in which polar winds were too weak to create waves or other dynamic features[6]. As northern spring approached...
