The 18th International workshop on Multi-scale (Un)-structured mesh numerical Modeling for coastal, shelf, and global ocean dynamics (IMUM 2019) will be held in historic Santa Fe, New Mexico, just 40 miles southeast of Los Alamos National Laboratory, over the dates of September 24-27, 2019. The workshop is organized by the Center for Nonlinear Studies at Los Alamos National Laboratory.

The IMUM workshops bring together researchers working on the development and implementation of unstructured-grid methods for simulation of oceanic processes over a wide range of scales from global ocean modeling to small-scale, nonhydrostatic modeling. Topics of discussion include but are not limited to:

• Finite-volume, finite-element, or spectral methods
• Numerical methods, including stability/accuracy analyses of existing methods, higher-order schemes, mimetic methods, pre-conditioners, advanced linear solvers
• Transport schemes
• Vertical coordinates and optimal horizontal/vertical grid design
• Mesh generation
• Adaptive mesh and/or polynomial refinement
• Parallel methods and high-performance computing
• Multiphysics applications including coupling to atmospheric, biogeochemical, wave, or sediment transport models
• Data assimilation
• Connecting the coastal to the global ocean
• Model validation studies and methods

Invited Keynote Speakers:

• Sergey Danilov on FESOM-C coastal model (AWI, Germany)
• Mike Herzfeld on COMPAS coastal model (CSIRO, Australia)
• Pierre Lermusiaux on ocean data assimilation and uncertainty quantification (MIT, USA)
• Luke Van Roekel on MPAS-O and coupled climate with E3SM (LANL, USA)
• Emmanuel Hanert on SLIM (UC Louvain, Belgium)
• Stephan Kramer on Firedrake (Imperial College, UK)
