I would like to thank the authors for their quick turn around with the revisions on the mansucript. Overall, I am happy with the changes made - but one suggestion that both reviewers identified requires further attention - the introduction. Reviewer 1 suggests re-writing the introduction - and the track changes for section indicate there are a few but not substantial changes here. Reviewer 2 also asks for a greater overview in the introduction - of which changes have been made in section 2 (study area not introduction) and in the supplemental material.
Therefore - before publication - I request that you revise the introduction - possibly combine it with the study area section (section 2) and provide a clearer context for the work. For the non specialist in the area (and ESurfs readership may be interested but not know all the details of the area and the issues) at present it is not completely clear what the issue you need to investigate is. So please - in the introduction - make sure you cover firstly what the research issue to be addressed is - what the knowledge gap lies. How previous studies have adressed this - and left the issue to be adressed - and finally how this paper aims to address those issues.
I have suggested these can be dealt with via minor revisions (review by editor) rather than sending the manuscript back out for review again. I look forward to the changes and think they will make the paper more broadly accessible.
All the best
Tom Coulthard
