PC54A:
High-Resolution Geochemical Proxies of Global Change: Progress, Problems, and Utility II Posters
Session ID#: 11500
Session Description:
Knowledge of climate and environmental change throughout geological time is derived from deep-sea and terrestrial records representing long time scales. While records of climate and environmental changes at long time scales are essential, high-resolution records at seasonal, annual, and decadal scales are equally important and under-represented in the literature. Much of what we know about past environments is based on the geochemical signature in various proxy archives. While substantial progress continues to be made in this area, specific obstacles and problems do exist. We encourage papers presenting geochemical records of global change, including calibration/validation studies, in biologic or inorganic carbonates, and highly resolved (decadal resolution) sediments. Geochemical studies highlighting recent progress, problems, or utility are especially welcome.
