The corrected version of the Acknowledgements also removes the following from the original version: 'The Zonally Accumulated Heat Transport in observation was calculated by N.P.H. from the National Ocean Center, United Kingdom'.Additionally, the following was originally omitted from the Author Contributions: 'N.P.H. calculated the observed Zonally Accumulated Heat Transport along the OSNAP east section'.This has been corrected in both the PDF and HTML versions of the Article.
