Keynote Speaker:
Itay Halevy (Weizmann Institute of Science)

Conveners:
Pan Zhang (Northwest University)
Mebrahtu Weldeghebriel (Princeton University)

Kang-Jun Huang (Northwest University)
Weiqiang Li (Nanjing University)

Full session description:
The chemical composition of seawater—encompassing major and trace elements,
isotopic compositions, alkalinity, redox conditions, pH, and salinity—has
fluctuated significantly throughout Earth's history. These changes provide
a unique and indispensable window into the complex interactions among
Earth's spheres, including the evolution of biosphere habitability, shifts
in atmospheric oxygen and carbon dioxide levels, the elemental and mineral
composition of the lithosphere, and material cycling between Earth's
internal and external layers. Understanding the long-term variations in
seawater chemistry, the key drivers behind these changes, and their
quantitative links to geological processes has greatly advanced our
knowledge of Earth's surface system evolution and long-term habitability.

This session invites contributions focused on the evolution of seawater
chemistry across various timescales, its implications for ocean
habitability, and its interactions with Earth's diverse spheres. We
encourage presentations that explore seawater chemistry evolution in the
geological record and the mechanisms driving it, through the development
and reevaluation of marine proxies and archives, experimental simulations,
data integration, numerical modeling, and big data approaches, aiming to
foster a comprehensive understanding of seawater chemistry evolution and
key geological processes across Earth's spheres.

Best regards,
Mebrahtu
