Co-author Bastiaan Jaarsma was accidentally omitted from the list of authors of the original published version of the article (Buijze et al, 2020). His name has therefore been retroactively added.
Bastiaan contributed significantly to the article and was essential to getting the paper published.
In addition, the address details given for Holger Cremer were incorrect. These should have read: 1TNO – Geological Survey of the Netherlands, Princetonlaan 6, 3584 CB Utrecht, the Netherlands.
