Numerical model of the semidiurnal ocean tide (M2) in the Gulf of Maine

Regional configuration of the MITgcm (Massachusetts Institute of Technology general circulation model) that allows users to reproduce some of the main results of the following study:

Schindelegger, M., Kotzian, D. P., Ray, R. D., Green, J. A. M., and Stolzenberger, S. (2022). Interannual changes in tidal conversion modulate M₂ amplitudes in the Gulf of Maine. Geophysical Research Letters, 49, e2022GL101671, https://doi.org/10.1029/2022GL101671.

Selected specifications of the MITgcm setup:

• Rectangular modeling domain on spherical polar grid
• Domain covers the Gulf of Maine, the Bay of Fundy, and the adjacent Northwest Atlantic
• Grid spacing: 2' (arcmin) telescoping to 11' at open model boundaries
• Classical z-coordinates, 57 vertical layers
• Forcing at open boundaries: Barotropic M₂ velocities and geostrophic background flow
• No astronomical forcing, no atmospheric forcing
• 20-day integrations can be run with climatological mean stratification or stratification of a particular year (1993 to 2019)
