Session Proposal: Advances in Speleothem Science: New Records, Methods, and Applications (AGU25)

PP002
Advances in Speleothem Science: New Records, Methods, and Applications

Session ID#: 248968

Session Description:
Speleothems, cave deposits, are valuable archives of paleoclimatic and paleoenvironmental change. They provide high-resolution, absolutely dated records that shed light on Earth system processes across timescales from the tropics to the poles. With a wide range of proxies, speleothems are capable of reconstructing diverse climatic variables such as precipitation, temperature, vegetation, permafrost, and fire history. They also serve as crucial benchmarks for evaluating and improving climate model simulations. This session invites contributions on all aspects of speleothem science, including novel records, proxy development, cave monitoring, methodological advancements, data syntheses, and proxy-model comparisons. We especially encourage submissions from early-career scientists.
