In the 2007/8 Antarctic summer season, 15 GPS receivers were deployed on (13) and around (2) the Filchner-Ronne and Larsen C ice shelves with the purpose of providing new tidal data and examining the tidal modulation of flow. Nine of the sites remained for the 2008 austral winter, 6 powered with over-winter power systems, and were retrieved in early 2009. Good data records have been obtained from each site (apart from FR01). Almost continuous, year-long records have been retrieved at FR05, FR07, FR09 and LAR2. The LAR2 site was left for a further year and will be retrieved in early 2010. Initial results from the tidal analysis from a subset of the sites is underway and these will be assimilated into a new Antarctic tide model in the near future in collaboration with Laurie Padman.
