A 5000-year record of relative sea-level change in New Jersey, USA

Stratigraphic data from salt marshes provide accurate reconstructions of Holocene relative sea-level (RSL) change and necessary constraints to models glacial isostatic adjustment (GIA), which is the dominant cause Late-Holocene RSL rise along U.S. mid-Atlantic coast. Here, we produce a new Mid- record marsh bordering Great Bay in southern New Jersey using basal peats. We use multi-proxy approach (foraminifera geochemistry) identify indicative meaning peats index points (SLIPs) that include vertical uncertainty for tidal range sediment compaction temporal based on high precision Accelerator Mass Spectrometry radiocarbon dating salt-marsh plant macrofossils. The 14 SLIPs 1211 ± 56 years BP 4414 112 BP, combine with published spatiotemporal statistical model show rose 8.6 m at an average rate 1.7 0.1 mm/year (1σ) 5000 present. compare changes ensemble 1D (laterally homogenous) site-specific 3D heterogeneous) GIA models, tend overestimate magnitude over last years. continued discrepancy between highlights importance wide array ice viscosity parameters more precisely fit
