Stable Isotope Sclerochronology of Melanopsis (Gastropoda) Shells: Inferring Late Pleistocene Seasonality in the Upper Jordan River Valley
Sub-weekly to sub-monthly records of δ 18 O and δ 13 C values in Melanopsis shells from the Jordan River Dureijat (JRD) archaeological site in the upper Jordan River Valley are assessed for changes in seasonal hydrology in the gastropod’s habitat, and these records are compared to results from one …

Investigation the use of oxygen and carbon isotopes and sclerochronology on Turbo sarmaticus and Donax serra for palaeoenvironment reconstruction at Pinnacle Point, South Africa
This thesis investigates the validity of oxygen isotope analysis for the gastropod Turbo sarmaticus (operculum and shell) and the bivalve Donax serra to reconstruct sea surface temperatures. These are the species most commonly retrieved from archaeological assemblages of the South Coast of South …

Interpreting environmental change using bivalve shell geochemistry
To further our understanding of Earth’s climate beyond historical records, a number of paleoclimate proxies are used to infer how climate has changed throughout Earth’s history. Examined herein are two such geochemical proxies—the δ¹⁸O of the shell of the Australian mud or flat oyster, Ostrea …

Seasonality in a changing climate: Insights from the modern ocean with application to the Eocene Epoch
<p>Climate change is arguably the most important issue facing modern society. One of the best tools we have for constraining future climate conditions comes from looking at warm and transitional intervals in Earth’s geologic past, such as the Eocene Epoch (~56-34 Ma). The Eocene Epoch was a time of …
