A new category of paper, the Opinion Editorial (Op-Ed) on Journal Advances in Polar Science was introduced in 2017, which attracts more attention from the international polar community. As Dr. Roger J. Braithwaite from the University of Manchester comments that this is a most welcome initiative! Up to now, five Opinion Editorials were published, you are welcome to query and discuss on each article by E-mail directly with the corresponding authors.

Op-Ed can be a statement of the opinion of a named author or authors (not necessarily affiliated with the editorial board) with a maximum of 15oo words (a maximum length of 2 printed pages). It will provide a forum for comment on the status and/or deficiencies on any aspect of polar science, reflect on recent innovation or progress, promote internationally collaborative polar science projects, etc. It will be directly reviewed by EICs with final decision without peer review by expert referrers.
