"As marine carbonates are deposited, they record chemical information about the seawater they were formed in. My project aims to describe and characterize the paleoenvironmental conditions that existed throughout the Late Triassic and Early Jurassic in the Parson Bay Formation of Northern Vancouver Island. This will be done through field stratigraphy of carbonate rocks located in both Port Alice and Holberg, as well as chemostratigraphy using isotope ratio mass spectrometry (IRMS). I aim to identify isotopic excursions in measured _­­­¹³C and ¹⁸O values and correlate them to changing paleoenvironmental conditions. Biostratigraphy of dinoflagellate cyst assemblages will also be used to further characterize these excursions."
