This research activity involves the analysis of stable isotopes in bulk carbonate samples. The goal is to understand the geochemical processes that have shaped the Earth's surface over time. By examining the isotopic composition of these samples, researchers can gain insights into the Earth's climate history, ocean circulation patterns, and the impact of human activities on the environment. This study aims to contribute to our understanding of the Earth's systems and their interactions, ultimately informing strategies for sustainable resource management and environmental conservation.
