  • IMPORTANT: Science never stands still and our understanding of natural depositional systems is constantly under revision. In the video, I mentioned that HCS and SCS indicate deposition on the shelf and that is no longer true. For years sedimentologists were reluctant to call the bedforms of combined flow by turbidity currents Hummocks and Swales and had to come up with terms like "plow-and-fill" to avoid critique by the community. Until 5 years ago "pseudo-hummocks" were gaining greater acceptance. Now we have the freedom to call these deepwater sedimentary structures Hummocks and Swales.
    Also, most sedimentologists have chosen to drop the idea of a Middle Shoreface - therefore in this video most of the succession you see which has stacked HCS and SCS would be part of a lower shoreface that is storm-influenced.
