| Zusammenfassung |
| We use ocean bottom-pressure measurements from 17 tropical sites to determine
the annual cycle of ocean mass. We show that such a calculation is robust,
and use three methods to estimate errors in the mass determination. Our final
best estimate, using data from the best sites and two ocean models, is that
the annual cycle has an amplitude of 0.85 mbar (equivalent to 8.4 mm of sea
level, or 3100 Gt of water), with a 95% chance of lying within the range
0.61–1.17 mbar. The time of the peak in ocean mass is 10 October, with
95% chance of occurring between 21 September and 25 October. The
simultaneous fitting of annual ocean mass also improves the fitting of bottom-pressure instrument drift. |
