[1] We use the leading empirical orthogonal functions (EOFs) of ocean bottom pressure (OBP) derived from an ocean model and the technique of EOF reconstruction to reduce noise in the large-scale OBP variations derived from the Gravity Recovery and Climate Experiment (GRACE). The subsequent OBP variations from the model and GRACE are then examined in the North Pacific between January 2003 and May 2007. Although annual and semiannual variations are similar, GRACE observes large interannual fluctuations poleward of 30°, where OBP increases from a low of nearly 3 cm below normal in early 2003 to normal throughout 2004 and 2005, …

The recent detailed analyses by Aubrey and Emery (1986) of Australian sea level trends continues their efforts to define tectonic and climatic factors worldwide that dominate long- and short-term fluctuations respectively in sea level records. These factors have included sediment and water loading on the adjacent shelf, the tectonic behaviour of plates, fluctuations in the Southern Oscillation, behaviour of currents impinging on the shelf, and river runoff. We do not object to these efforts; however we are disturbed by misrepresentations in their recent paper on Australian sea levels regarding (1) the interpretation of the nature of sea-level records, (2) the …
