Ocean–Climate Interactions Through Time: Insights from the Marine Sedimentary record

Session ID#: 254086

Session Description:
There is a fundamental interplay between the ocean and Earth’s climate system. Throughout geological history, major climatic transitions, such as the Holocene–LGM, Mid-Pleistocene Transition, the Oligocene–Miocene boundary, have been marked by profound oceanic changes, including shifts in temperature, circulation, sea level, biogeochemistry, and marine ecosystems. These changes can be reconstructed through the study of chemical and biological indicators preserved in marine sediments and water, known as proxies.

This session aims to develop a broad understanding of how ocean systems have responded to climate variability through time, using proxy records from water and sediments. By examining these transitions, we gain insight into the mechanisms that have shaped Earth’s climate and explore their relevance to ongoing and future climate change.

We welcome contributions across a wide range of temporal scales, from long-term changes and Milankovitch cyclicity to short-lived events. Studies may span from the Precambrian to the Holocene and may use single or multiproxy approaches, with regional or global focus. We invite presentations focused on proxy-based reconstructions of paleoenvironmental conditions and processes, with particular emphasis on their relationship to paleoclimatic transitions within Earth's climate system.
