contribution to the pelagic ocean mixing. Observational support comes from tidally induced fortnightly and monthly temperature variations in the Indonesian Seas ( Ffield and Gordon 1996 ) and from measurements of ocean microstructure in the deep Brazil Basin revealing mixing over topography with enhanced intensity at spring over neap tides ( Polzin et al. 1995 , 1997 ; Ledwell et al. 2000 ). The Hawaii Ocean-Mixing Experiment (HOME), a major experiment along the Hawaiian Island chain dedicated to tidal

understanding of the changes of the ocean’s transports, a wider analysis of changes in the ocean’s local and global mass, heat, and salt content, as well as of the related sea level changes, need to be considered. In principle, an ocean synthesis provides the framework for such a combined estimate of the time-varying circulation of the ocean that is consistent with prior model and data error descriptions. The global ECCO ocean-state estimation effort supplies an estimate of the time-varying ocean

sensitivity study using the MITgcm adjoint was undertaken by Marotzke et al. (1999) , who investigated the (tangent) linear sensitivity of the meridional heat transport in the Atlantic. Bugnion (2001) and Köhl (2005) extended this study to climate time scales and to higher resolution, respectively. Other examples are the study of SST anomalies in the North Atlantic ( Junge and Haine 2001 ), midlatitude–ENSO teleconnection mechanisms ( Galanti and Tziperman 2003 ; Galanti et al. 2002 ), the deep

spatial patterns of the SSH variability to the west of 70°E, however, are different from those at 90 and 60 days. The phase patterns here are more complex. In the southwest region the phase shows westward propagation with an amphidrome near 10°S, 50°E. This phase pattern suggests the effects of the northern tip of the island of Madagascar (near 12°S, 49°E). North of the equator, there is also some westward propagation between 55° and 70°E, probably caused by locally forced Rossby waves. 8. Effects on

permits the δ 13 C and Δ 14 C observations to be unaltered in the presence of a stronger transport, and in the case of the density tracer, for the barotropic flux in the boundary current to be adjusted without bound. The ability to constrain the meridional transport is curtailed when interior points of the model domain are left unspecified. Making observations at seamounts, islands, and ridges may thus provide valuable constraints on the circulation. Specification of nonzero covariance between

Gibraltar). However, the model can be expected to reasonably simulate aspects of large-scale averages and their variability. In fact, as discussed in the following sections, despite its limited spatial resolution, the model is fairly capable at simulating the basin-wide fluctuation of the Mediterranean Sea. The model employs a free-slip boundary condition, an implicit free surface, and is forced by 12-hourly surface wind stress and daily heat and freshwater fluxes. The fluxes are based on the reanalysis
