Holocene relative sea-level rise of the Delaware Estuary, USA
Holocene relative sea level (RSL) rise of the mid-Atlantic United States is dominated by two processes: ice-equivalent sea-level changes and Glacial Isostatic Adjustment (GIA) driven vertical land motion. Interpreting Holocene RSL processes in the Delaware Estuary is limited by the availability of RSL data: just 26% of 49 published sea-level index points (SLIPs) were older than 3000 years BP. Here, we extend the RSL history of the Delaware Estuar…
Salt-Marsh Foraminiferal Distributions from Mainland Northern Georgia, USA
We investigated foraminiferal distributions from two salt-marsh sites at Thunderbolt and Georgetown, in mainland northern Georgia, U.S. Atlantic coast. We analyzed modern epifaunal foraminiferal assemblages across multiple transects consisting of 54 surface samples. Multivariate statistical analysis (Partitioning Around Medoids and Detrended Correspondence Analysis) revealed that dead foraminiferal assemblages are divided into three faunal zones,…
Identifying the Greatest Earthquakes of the Past 2000 Years at the Nehalem River Estuary, Northern Oregon Coast, USA
We infer a history of three great megathrust earthquakes during the past 2000 years at the Nehalem River estuary based on the lateral extent of sharp (≤3 mm) peat-mud stratigraphic contacts in cores and outcrops, coseismic subsidence as interpreted from fossil diatom assemblages and reconstructed with foraminiferal assemblages using a Bayesian transfer function, and regional correlation of 14C-modeled ages for the times of subsidence. A subsidenc…
Testing the Utility of Geochemical Proxies to Reconstruct Holocene Coastal Environments and Relative Sea Level
On low-lying, tropical and sub-tropical coastlines freshwater marshes may be replaced by salt-tolerant \nmangroves in response to relative sea-level rise. Pollen analysis of radiocarbon-dated sediment cores \nshowed that such a change occurred in Hungry Bay, Bermuda during the late Holocene. This well-established paleoenvironmental trajectory provides an opportunity to explore if geochemical proxies (bulk-sediment δ13C and Rock-Eval pyrolysis) ca…
