The ECCO global WOCE synthesis is used to analyze ocean volume, heat |
6 |
and freshwater transports. Time-mean horizontal transports, estimated |
7 |
from this fully time-dependent constrained circulation, are now generally |
8 |
consistent with the time-independent inverse estimates from box inversions, |
9 |
with especially good agrement in the southern hemisphere. |

The estimated mean circulation around Australia involves a net volume |
12 |
transport of 11 Sv through the Indonesian Throughflow and the Mozambique |
13 |
Channel. This flow regime exists on all time scales longer than one |
14 |
month---rendering the variability in the South Pacific strongly coupled |
15 |
to that in the Indian Ocean. |

Dynamically consistent variations in the model show temporal variability |
18 |
of oceanic heat transports, heat storage and atmospheric exchanges that |
19 |
are complex and with a strong dependence upon location, depth, and |
20 |
time-scale. One can now study the dynamics of both the mean and time |
21 |
variability from the model with the reassurance that it is consistent |
22 |
with the great bulk of the WOCE observations. |
