Climate change in the Arctic during the Holocene is reconstructed using shell carbonate isotopes from the bivalve species, Serripes groenlandicus, which were collected from various sites in Svalbard, Norway. The Serripes shells were hand sampled on consecutive growth bands for δ18O isotopes to develop temperature reconstruction models. The shell ages span throughout the Holocene, encompassing the multiple cycles of known warm and cold periods, including the Holocene Thermal Maximum. This study aims to reconstruct a timeline of discrete marine temperature fluctuations in Isfjorden, Svalbard, and will allow for improved predictions of the impacts of future human-induced climate change.
