The contribution of glacial isostatic adjustment to projections of sea‐level change along the Atlantic and Gulf coasts of North America

We determine the contribution of glacial isostatic adjustment (GIA) to future relative sea-level change for the North American coastline between Newfoundland and Texas. We infer GIA model parameters using recently compiled and quality-assessed databases of past sea-level changes, including new databases for the United States Gulf Coast and Atlantic Canada. At 13 cities along this coastline, we estimate the GIA contribution to range from a few centimeters (e.g., 3 [−1 to 9] cm Miami) to a few decimeters (e.g., 18 [12][13][14][15][16][17][18][19][20][21][22] cm, Halifax) for the period 2085-2100 relative to 2006-2015 (1− ranges given). We provide estimates of uncertainty in the GIA component using two different methods; the more conservative approach produces total ranges (1− confidence) that vary from 3 to 16 cm for the cities considered. Contributions from ocean steric and dynamic changes as well as those from changes in land ice are also estimated to provide context for the GIA projections. When summing the contributions from all three processes at the 13 cities considered along this coastline, using median or best-estimate values, the GIA signal comprises 5-38% of the total depending on the adopted climate forcing and location. The contributions from ocean dynamic/steric changes and ice mass loss are similar in amplitude but with spatial variation that approximately cancels, resulting in GIA dominating the net spatial variability north of 35 ∘ N.

“…By ϳ12,000 14 C yr B.P., sea levels were about 95 m lower than modern levels, rising to about Ϫ33 m by 10,000 14 C yr B.P., moving Florida's coastline to within 60-130 km of its present location. The Gulf continental shelf is also karstic, and the same general geomorphology found today on the coastal plain was likely present on the exposed shelf during the Paleoindian Period (Faught & Donoghue, 1997).…”

“…In its lower reaches, the river disappears underground and breaches the surface in a series of sinkholes until it emerges at Nuttal Rise, where it flows to the Gulf of Mexico (Florida Department of Natural Resources, 1989). At times of low water, the majority of the river's length was likely a linear series of sinkholes, which can also be traced offshore (Faught & Donoghue, 1997).…”

Freshwater availability as the constraining factor in the Middle Paleoindian occupation of North‐Central Florida

The locations of reliable surface water exposures during the Middle Paleoindian period (10,200 14 C yr B.P.) in north-central Florida are reconstructed and compared to the concentrations of Middle Paleoindian projectile points. Estimates of water table levels and surface water flow in Florida's karst geology confirm prior climate reconstructions for that time indicating the area was arid and supported a xeric ecology in most upland locales. Surface water flow data from recent extreme droughts and water table estimations are used to identify the areas of highest probability for surface water availability. The distribution of the highest concentrations of Middle Paleoindian points correlates with the areas of highest probability, indicating that scarce surface water sources were the strongest constraint on occupation location during that time.

“…Archaeologists have long recognized the potential for discovering sites of Pleistocene and early Holocene age in coastal areas subject to repeated exposure and submergence (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23), although these efforts have typically focused on marine environments that were subject to global changes in sea level. During the past year, investigators from the Museum of Anthropology and the Marine Hydrodynamics Laboratories at the University of Michigan have begun the task of testing whether human occupation sites are present on the Lake Stanley causeway beneath Lake Huron.…”

Evidence for early hunters beneath the Great Lakes

Scholars have hypothesized that the poorly understood and rarely encountered archaeological sites from the terminal Paleoindian and Archaic periods associated with the Lake Stanley low water stage (10,000 -7,500 BP) are lost beneath the modern Great Lakes. Acoustic and video survey on the Alpena-Amberley ridge, a feature that would have been a dry land corridor crossing the Lake Huron basin during this time period, reveals the presence of a series of stone features that match, in form and location, structures used for caribou hunting in both prehistoric and ethnographic times. These results present evidence for early hunters on the Alpena-Amberley corridor, and raise the possibility that intact settlements and ancient landscapes are preserved beneath Lake Huron.Lake Stanley ͉ Paleoindian period ͉ underwater archaeology ͉ Lake Huron ͉ caribou I t is difficult to consider the early prehistory of the Great Lakes region without reference to the slow withdrawal of the continental ice sheet, and the subsequent rises and drops in the waters of the Great Lakes that accompanied the region's gradual transition to its modern appearance. Much of what is known of the early human occupation derives from the periods of high water and relict beaches. For times associated with low water, there are few sites. Some are found deeply buried beneath later lake sediments, and most are presumed lost forever beneath the lakes. New high-resolution bathometry of the Great Lakes, coupled with advances in 3D surface modeling, make it possible to view once again the ancient landforms from these low-water periods. This in turn raises the possibility of discovering early human settlements and activity sites preserved beneath the lakes. Here we report evidence for human activity on the AlpenaAmberley ridge-a structure that, during the Lake Stanley low-water phase, would have provided a land causeway across the middle of modern Lake Huron linking northern Michigan with central Ontario.The post-glacial history of the Great Lakes is characterized by a series of high and low water stands regulated by the interaction of early Holocene climate, the flows of glacial melt waters, and the isostatic rebound of recently de-glaciated land surfaces (1, 2, 3). The most extreme of the low-water stands is referred to as the Lake Stanley stage in Lake Huron (and the Lake Chippewa stage in the Lake Michigan basin) (4), which spanned from approximately 9,900 BP to 7,500 BP and was associated with lake levels as low as 55-80 m above mean sea level (AMSL), compared with the modern standard of 176 m AMSL (Table 1). When projected at a level of 90 m AMSL, the Lake Huron basin contains 2 lakes separated by a ridge or causeway extending northwest to southeast across the basin from the area of Presque Isle, MI, to Point Clark in Ontario (Fig. 1). The causeway, designated the AlpenaAmberley ridge, averages 16 km in width and is capped with glacial till and Middle Devonian limestone and dolomites (5, 6).The earliest human occupation in the upper Great Lakes is associated ...
