What’s Next for Science

Each year, AGU’s annual meeting, the largest gathering of Earth and space scientists, convenes 25,000+ attendees from 100+ countries to share research and connect with friends and colleagues. Scientists, educators, policymakers, journalists and communicators attend AGU24 to better understand our planet and environment, opening pathways to discovery, opening greater awareness to address climate change, opening greater collaborations to lead to solutions and opening the fields and professions of science to a whole new age of justice equity, diversity, inclusion and belonging.

Abstract Deadline: 31 July 2024 (23:59 EDT/03:59 +1 GMT)

GEOTRACES sessions:

*OS013 – Disentangling Hydrothermal Impacts on Ocean Biogeochemistry
https://agu.confex.com/agu/agu24/prelim.cgi/Session/230146

Exciting new research reveals the significant impact of submarine hydrothermal venting on ocean biogeochemistry at both basin and global scales. Understanding this impact requires examining processes across various scales and integrating multiple disciplines, including observations, experiments, data synthesis, and modeling. This session invites submissions on hydrothermal biogeochemistry research across all venting styles and scales. It aims to connect drivers of hydrothermal processes from marine geoscience, organic geochemistry, ocean circulation, carbon and biogeochemical cycles, and marine microbiology. We especially welcome contributions from international programs like GEOTRACES and InterRidge, and novel research on diverse seafloor fluid flow systems worldwide, such as mid-ocean ridges, intraplate seamounts, convergent margins, and transform faults. Field, laboratory, and theoretical studies on the roles of hydrothermal systems in the cycling and transformation of organic matter and nutrients in the oceans are also encouraged.

*OS038 – Trace Element Distributions and Cycling Across Ocean Basins
https://agu.confex.com/agu/agu24/prelim.cgi/Session/228153

Marine trace elements and their isotopes regulate primary production and provide tracers of past and present oceanic processes, including circulation and particle export. The influence of trace elements on productivity and the ocean carbon cycle is particularly notable in the remote Southern Ocean, where distant or ice-covered continents provide reduced inputs and water mass circulation impacts global transfer of heat and nutrients. A number of recent expeditions have sampled these waters, providing new data on tracing external elemental fluxes to the region, constraining complex biogeochemical processes, and measuring their imprint on subsurface water masses. This session invites presentations addressing the sources, sinks, and cycling of trace elements in the ocean, particularly as studied using ocean basin sections. Results from fieldwork and/or modeling studies in the Southern Ocean, Antarctic Circumpolar Current, and Antarctic coastal waters are particularly encouraged, though results from all ocean basins are welcome.
