The recently published paper in CJES by Sookhan et al. presented challenging interpretations regarding ice streams and the origin of the Oak Ridges Moraine (ORM. As researchers we welcome ongoing work and continual testing of existing interpretations. As the most active research group working on the Oak Ridges Moraine during the past 25 year period, additional contributions and perspectives are welcomed as a necessary part of ensuring advancement of geological interpretation and hypothesis testing. This is particularly pertinent given the statement by Sookhan et al. that the ORM is the most significant landform in southern Ontario and the importance of ORM to ongoing management of groundwater resources in this region.
Summary(Plain Language Summary, not published)
The author presents a discussion of a recently published paper in CJES that violates three of the principal research ethic guidelines of the journal. The Discussion piece outlines these violations with examples.
