The authors have made a serious effort to answer the comments of the reviewers and the paper can now be published following proof reading (there are still a number of spelling and grammatical errors) and the addition of two short statements:.

1. Reviewer 1 raised the question of how the authors calculated their meridional transports and why they did not calculate the volume flux crossing 30° and 35°S based on the actual direction of the current flow, rather than assuming it to be south to north. In their response, the authors show that to calculate the flow you have to include cosθ, where θ is the angle of flow relative to N-S, but the question is not how to calculate this quantity, but whether the authors made allowance for the fact that the flow is north-westward rather than northwards, and used cosθ in their calculation. They don’t say whether they did this.

2. Reviewer 1 also asked about the length of the time series used to calculate the standard deviations of the transport. The authors claim they have added this (p6, line 30) but such a statement does not appear anywhere in this paragraph.

If the authors can add statements on these aspects, then I do not need to see the manuscript again.

Thank you for making the latest changes.
