A multi-proxy modern training set for reconstructing Holocene relative sea level using salt-marsh sediment (Prince Edward Island, Canada)

Canadian Journal of Earth Sciences, Ahead of Print.Reconstructing Holocene relative sea-level change from salt-marsh sediment requires a modern training set that captures the observable relationship between proxies and local tidal elevation. We collected 143 surface sediment samples from four salt marshes in Prince Edward Island (PEI, Canada) to develop a modern training set of foraminifera and bulk-sediment δ13C and δ15N values. Two sites have semi-diurnal tidal regimes, one has a m
