seasonal cycle in ocean bottom pressure
[1] Seasonal variability in ocean bottom pressure pb is analyzed using GRACE (Gravity Recovery and Climate Experiment) data products and an optimized model solution obtained by fitting most available ocean data in a leastsquares sense. The annual cycle in the spatial mean is a substantial part of th...
