Yes, local sea levels are falling around Greenland because the loss of ice mass reduces gravitational pull on surrounding ocean water. Would it make sense for it to recede at this level with sources of fresh water relatively close? A gulf is typically larger than a bay and may be connected to the ocean. These strata, which are known as the Richmond Gulf Group, rest unconformably on Archean crystalline rocks of the Superior craton and are now preserved by downfaulting only within the Richmond Gulf Graben. gulf vs bay.
