The article discusses a study which observes Repeated Global Navigation Satellite Systems (GNSS) that were carried out at 50 surface markers in the Vostok Subglacial Lake in East Antarctica region between 2001 and 2011. It says that mean surface accumulation rates are inferred for four surface segments which were based on the observed flow velocity vectors and ice thickness data. It mentions that remote-sensing techniques such as satellite interferometric synthetic aperture radar (InSAR) are common tools for the influence of flow velocity fields. It adds that ice dynamic modeling is another information source which might constrain the regional flow velocity field.
