Date of model runs:

  Model was run for 50 model days - arbitrary dates

Runs were done in 2019-11 to 2020-02 using the Regional Ocean Modeling System

DATA & FILE OVERVIEW

--------------------

There are 3 experiments, each with 2 runs: one run uses a bathymetry of a straight shelf incised by a submarine canyon (code CR= canyon run) and the other one uses a straight shelf with no canyon (code NCR= no canyon run). Each experiment has a different shelf slope: DS= deep shelf, IS=Intermediate shelf, SS=Shallow shelf. In this numerical experiments, a coastal trapped wave of period 7 days, imposed at the southern boundary, propagates along the shelf for 50 model days, passing over a submarine canyon. All experiments are initialized with the same horizontally uniform temperature and salinity profiles.

In summary:
CR_DS: Uses the bathymetry of a straight shelf incised by a submarine canyon and a deep shelf (smallest shelf slope).
NCR_DS: Uses the bathymetry of a straight shelf and a deep shelf (smallest shelf slope).

CR_IS: Uses the bathymetry of a straight shelf incised by a submarine canyon and an intermediate shelf (intermediate shelf slope).
NCR_IS: Uses the bathymetry of a straight shelf and a deep shelf (intermediate shelf slope).

CR_SS: Uses the bathymetry of a straight shelf incised by a submarine canyon and a shallow shelf (largest shelf slope).
NCR_SS: Uses the bathymetry of a straight shelf and a shallow shelf (largest shelf slope).

Files uploaded here contain a subset of the domain; they only contain the area around the canyon (highest spatial resolution). The original domain was 400 km by 800 km, and here we share a region of 40 km from the coast (the shelf width) by 80 km alongshore (40 km to either side of the canyon axis).
