This session focuses on reconstructing past climate change through the analysis of marine biotic and sedimentary archives across geological time, from deep time to the Recent. Contributions will explore how climatic variability and environmental change are recorded in marine fossil assemblages, marine sediments, and sedimentary rocks, and how these records can be used to infer past climate dynamics and ecosystem responses in the ocean–climate system. ARCHES welcomes studies based on marine paleontological, sedimentological, stratigraphic, and geochemical data. Particular attention will be given to marine proxy-based reconstructions, methodological developments, and case studies that link biological and sedimentary signals to climate and paleoceanographic change. Multi-proxy perspectives are encouraged, but contributions focusing on individual marine archives, proxies, or methods are equally welcome. By bringing together diverse datasets and approaches, this session aims to improve our understanding of marine Earth system sensitivity, biotic resilience, and the mechanisms governing ocean–climate–sediment interactions through time. Insights from past climate change preserved in marine records provide essential context for interpreting ongoing environmental change and anticipating future impacts on marine ecosystems.
