A05 Geoarchaeology: humans, landscapes, climate and ecology
Conveners: Christine Hatte, Natalia Piotrowska
Human activity has an impact on the environment and the landscape. We invite papers presenting radiocarbon chronologies applied in interdisciplinary studies (paleoclimate, geomorphology, geochemistry, ecology) of archaeological sites and their environmental context. Papers dedicated to improved chronologies and dating transition between cultural/archaeological/climatic phases in different geographic locations are welcome.
A06 Art and Cultural Heritage
Conveners: Anita Quiles, Lior Regev, Alex Bayliss
Radiocarbon dating is often used in protection and conservation studies of tangible cultural heritage. This session will focus on dating prehistoric and historic objects, including buildings and urbanistic environment. We invite papers dedicated to radiocarbon dating of specific materials (support material, paint, mortars, pottery and more) and to high precision dating e.g. by using wiggle matching, Bayesian models and cosmic events.
A07 Radiocarbon and the Protection of Cultural Heritage
Conveners: Irka Hajdas, Timothy Jull
Radiocarbon community is working for protection of cultural heritage. In this session we discuss the issue of radiocarbon dating being used to date antique objects. Examples of illicit/suspicious objects from laboratories are welcome.
Global and Regional Carbon Cycles (G)
G01 Atmospheric radiocarbon
Conveners: Sönke Szidat, Jocelyn Turnbull
This session is designed to highlight measurement and modelling studies of radiocarbon in atmospheric CO2, methane and other atmospheric components such as aerosols in the context of local to global-scale carbon cycling, with the goal of constraining sources and sinks of these components and their dynamics in response to natural processes and anthropogenic perturbations.
G02 Oceanic carbon cycling
Conveners: Brett Walker, Thomas Blattmann, Maxi Castrillejo, Roberta Hansman
This session provides a forum for presenting radiocarbon-based investigations related to different facets of the oceanic carbon cycle spanning different carbon pools (dissolved inorganic and organic carbon, suspended, sinking and sedimentary particulate carbon), coastal and open ocean systems and all ocean realms (surface to abyssal/hadal waters) and their links to ocean ecosystems.
G03 Freshwater aquatic continuum
Conveners: Philippa Ascough, Nathalie Dubois
Contributions are welcome for diverse studies focusing on the application of radiocarbon to examine specific aspects or the entirety of the freshwater aquatic continuum, including soil and ground waters, streams and rivers, wetlands and lakes. Examples include use of radiocarbon observation and/or modelling approaches to explore carbon sources and turnover, carbon flow through aquatic food webs, and exchange with different reservoirs along the aquatic continuum.
G04 The polar carbon cycle – radiocarbon in the cryosphere
Conveners: Gesine Mollenhauer, Lisa Broeder
Contributions are solicited for studies focusing on diverse aspects of carbon cycling in polar regions as well as at high elevations (the “third pole”), including glacial processes, permafrost carbon dynamics, high latitude/elevation ecosystems, and land-ocean interactions in polar regions.

The terrestrial carbon dynamics session encourages submission of contributions focusing on radiocarbon-based investigations of different components of terrestrial ecosystems and associated landscapes. Topics including studies of vegetation and soil dynamics in forest, grassland and agricultural systems, as well as the influence critical zone processes (e.g., climate, lithological and topographic controls on weathering, erosion and soil formation/stability), and application of novel radiocarbon modelling approaches (e.g., using bomb-spike and other transient signals).
