Dynamical systems for ocean science: Understanding complexity

Session ID#: 258533

Session Description:
The ocean is a nonlinear, multiscale and chaotic system evolving under time-dependent forcing. To advance ocean modeling, guide experiment design and extract understanding from a rapidly growing collection of observed and simulated data, we need the best mathematical ideas and tools. Concepts from dynamical systems theory have enabled fundamental insights into ocean variability, stability and predictability. Integrating these theoretical perspectives into applied ocean science could help address key societal challenges linked with a changing future ocean, e.g. by reducing uncertainties and providing interpretable, generalizable predictions.

This interdisciplinary session will bring together scientists at the interface of oceanography, applied mathematics, and complex systems. We welcome contributions related to physical and biogeochemical processes as well as conceptual and computational studies:

Dynamics and complexity

  • nonautonomous dynamical systems
  • statistical mechanics and thermodynamics
  • multistability and critical transitions
  • chaos and turbulence
  • stochastic processes and parameterizations
  • response theory and fingerprinting
  • causality and forced versus internal variability

Computational and data-driven methods

  • numerical techniques and PDEs
  • dimensionality reduction and reduced-order models
  • transfer and Koopman operators
  • network theory
  • machine learning
Co-Sponsor(s):
  • Digital Ocean -
  • Physical-Biological Interactions -
