Accuracy assessment of ocean tide models around Antarctica
Accurate ocean fide models for the circum-Antarctic seas are required to remove unwanted signals from floating ice elevation and space-borne, time-variable gravity measurements (e.g., GRACE). We present accuracy assessments for several global (CSR4, FES2004, FES99, GOT00.2, NAO.99b, TPXO6.2) and Ant...
