OS – Ocean Sciences

Programme Group Chair: Joanna Staneva

OS1 –  Ocean Circulation and Climate

Sub-Programme Group Scientific Officer: Joke Lübbecke

OS2 –  Coastal Oceans, Semi-enclosed and Marginal Seas

Sub-Programme Group Scientific Officer: Sandro Carniel

OS3 –  Ocean Biogeochemistry and Biology

Sub-Programme Group Scientific Officer: Peter Landschützer

Proposals are marked in red.

Session short summary:
The oceanic biological carbon pump (BCP) transfers organic carbon from the surface to the deep ocean, regulating atmospheric CO₂ and climate. A major uncertainty is marine snow sinking velocity, which varies with particle properties and is affected by vertical ocean velocities (~1 mm/s). We invite studies combining observations, experiments, and modelling to improve BCP representation.

Suggested session
Tides and Storm Surges
Session short summary:
This session welcomes contributions that use in situ observations, remote sensing, numerical and data-driven models, and geological/paleo-reconstructions to advance understanding of tide- and/or surge-driven processes, their broader implications for coastal, ocean, and Earth system dynamics, and applications to tidal energy, navigation, and beyond. We invite submissions spanning regional to global scales, past, present, and future perspectives, and settings ranging from estuaries and rivers to the open ocean and other planetary bodies.
Keywords: Coastal seas, Ocean circulation, Sea level, Weather extreme events
Co-organization suggestions:
G3 | Geodynamics and Earth Fluids
