Short summary
This study documents previously unknown, shallow sediment stratigraphic archaeal zones that extend over a large section of the Scotian Slope of Northeastern Canada. These zones appear to be geochemically and not lithologically controlled. They are also not detectable by using traditional lipid biomarker ratios. They indicate subsurface microbial community structures to be more complex and tractable over large expanses of the continental margins.
