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.

“…The minimum sea-level curve was developed using Caribbeanwide A. palmata sampled from well-documented shallow reef-crest framework [e.g. Lighty et al (1978), east Florida] or cored from reef crest features in other localities [referenced in Lighty et al (1982)]. A. palmata exhibits growth rates of as much as 14 mm year )1 , and may be a continuous tracer of SLR, provided that the rate of rise does not exceed this maximum growth rate.…”

Corrected western Atlantic sea-level curve for the last 11,000�years based on calibrated 14C dates from Acropora palmata framework and intertidal mangrove peat

2003

A corrected western Atlantic Holocene sea-level curve was constructed from 145 calibrated 14 C and TIMS U-Th dates from shallow Acropora palmata framework and intertidal Rhizopora mangle peat from the Florida Keys, Belize, and the wider Caribbean. Data include both previously published and newly reported coral and peat dates. With the elevations of corals restricted to positions below sea level and those of peats to intertidal and higher levels, a curve bracketed by corals below and peat above effectively delineates the positions of a rising Holocene sea. From 3-11 ka, the corrected curve shifts progressively to older calibrated ages, reaching an $1-kyr increase at )21 m MSL (mean sea level). Elevations and calibrated ages of samples from each locality in the wider Caribbean region constitute an important database for future refinement with glaciohydro-isostatic elevation corrections from 3-D Earth models. In future studies of the history of western Atlantic coral reefs, scientists will be able to relate calibrated radiocarbon dates to this sea-level curve to determine paleo water depths and rates of sea-level rise.

“…In some areas, numerous distinct relict reef ridges are present (Lighty, Macintyre, and Stuckenrath 1978) while in other areas there is a gradational separation (Toscano and Macintyre 2003). These relict Holocene reefs, comprised primarily of A. palmata, are found at water depths between 20 and 7 m south of Miami and between 27 and 7.8 m depth to the north (Toscano and Lundberg 1998;Toscano and Macintyre 2000).…”

“…In fact, major Acropora-dominated reefs were well-developed off Palm Beach County (Lighty 1977;Lighty, Macintyre, and Stuckenrath 1978), indicating that water quality along the platform margin was more favorable to coral growth than today. A buried topographic feature lying off Fort Pierce may be the northernmost extent of this mid-Holocene reef tract (Hine 1997).…”

“…In south Florida, such drowned shelf features have been identified using high-resolution seismic, side-scan sonar and in situ sampling by submersibles in water depths of 50 to 124 m (Locker et al 1996). Although the rate of rise in sea level during the Holocene (the last 10 ky) has never exceeded the maximum accretion rate of A. palmata, reef growth was not continuous but punctuated by a series of reef ridges and troughs (Lighty 1977;Lighty, Macintyre, and Stuckenrath 1978;Toscano and Lundberg 1998;Precht et al 2000;Lidz, Reich, and Shinn 2003).…”
