| The impact of self-attraction and loading (SAL) on ocean bottom pressure xi, an effect not previously considered, is analyzed in terms of the mean annual cycle based on decade long estimates of changes in land hydrology, atmospheric pressure, and oceanic circulation. The SAL-related changes in xi occur as a result of deformation of the crust due to loading and self-gravitation of the variable fluid loads. In the absence of SAL, net freshwater input and changes in mean atmospheric pressure over the ocean give rise to a spatially constant xi annual cycle with an amplitude similar to 1-2 cm in equivalent water thickness. Consideration of SAL physics introduces spatial variations that can be significant, particularly around continental boundaries, where the... |
