We examined the use of δ13C, TOC and C/N geochemistry of sedimentary organic matter to reconstruct former sea levels and paleoenvironments in the absence of suitable microfossil data. The modern distribution of δ13C, TOC and C/N of 33 vegetation and 74 surface sediment samples collected from four coastal wetlands in the Thames Estuary and Norfolk, UK are described. The δ13C, TOC and C/N geochemistry of sediments varied in relation to the input of in situ vascular vegetation versus allochthonous… 

Carbon stable isotope (δ13C) and elemental (TOC, TN) geochemistry in saltmarsh surface sediments (Western Brittany, France): a useful tool for reconstructing Holocene relative sea‐level

Providing a dense network of Holocene relative sea‐level (RSL) records still faces some challenges, such as the paucity of microfossil assemblages within some Holocene sedimentary sequences.

This thesis presents new late Holocene relative sea-level reconstructions in the Humber Estuary, and examines the relationship between sea-level change and the salinisation of the groundwater

A 7000‐year high‐resolution lake sediment record from coastal central Chile (Lago Vichuquén, 34°S): implications for past sea level and environmental variability

We present a 7‐ka environmental reconstruction based on sedimentological and geochemical data from Lago Vichuquén, a coastal eutrophic lake in central Chile (34°48′S, 72°03′ W, 4 m a.s.l.). A

Source organic matter analysis of saltmarsh sediments using SIAR and its application in relative sea‐level studies in regions of C4 plant invasion

The introduction of invasive Spartina grasses (C4 plant) into previously C3‐dominated saltmarshes of western Europe complicates the reconstruction of past relative sea‐level (RSL) using sediment

The distribution and utility of sea‐level indicators in Eurasian sub‐Arctic salt marshes (White Sea, Russia)

In support of efforts to reconstruct relative sea level (RSL), we investigated the utility of foraminifera, diatoms and bulk‐sediment geochemistry (δ13C, C:N and parameters measured by Rock‐Eval

Advances in palaeoenvironmental research are identified that could enhance restoration efforts and help maximise the ecosystem services delivered through such projects.



Modern foraminifera, δ13C, and bulk geochemistry of central Oregon tidal marshes and their application in paleoseismology

Use of carbon isotope and C/N geochemistry in reconstructing vegetation communities: a mid- to late- Holocene palaeoenvironmental investigation from Romney Marsh, Kent, UK

The use of stable carbon isotope geochemistry and C/N ratios for coastal palaeoenvironmental reconstructions is a relatively new and under-researched field. This research seeks to understand the

Bulk organic δ13C and C/N ratios as palaeosalinity indicators within a Scottish isolation basin

Microfossils in isolation basin sediments are frequently used to reconstruct sea‐level change, but preservation problems and non‐analogue situations can limit their usefulness. Here we investigate
