The authors have informed us of the following errors in their published article:
Errors were published with respect to the value of the moving average window, $ \mathrm{\ell} $ . Each value of $ \mathrm{\ell} $ used in the study was in fact one fourth the value reported (e.g. instances of “ $ \mathrm{\ell}=100 $ dbar” should instead read “ $ \mathrm{\ell}=25 $ dbar”).
Additionally, instances of “20 times the typical layer thickness” should instead read “five times the typical layer thickness.”
The authors apologize for this error. This does not affect the results or interpretations in the text.
