Temperature timeseries and idealized simulations of internal solitary waves colliding with the Grande-Anse wharf, Saguenay Fjord, Canada

In 2019, the Motor Vessel Jaeger Arrow collided with the Grande-Anse Terminal wharf (Saguenay Fjord, Canada) during docking from unknown causes. However, the timeline of the incident and the ship's behavior during docking suggest that underwater waves may have caused the collision. Data collected in 2023 using a camera and thermometers confirmed that this area of the fjord regularly experiences underwater waves with wavelengths ranging from 50 to 100 m, wave heights of 1 and 3 m, and periods of around 2 min. These waves frequently collide with and reflect off the wharf, generating currents of 0.1 to 0.3 m s-1. Numerical simulations further illustrate the interactions between the waves and the wharf, highlighting regions near the wharf where wave-induced currents, both inshore and offshore, occur, including areas with near-zero currents that could create a false sense of calm conditions. Importantly, our observations also revealed that large ships, such as the Jaeger Arrow, can generate ..., This dataset includes:
1) Temperature, salinity, and pressure measurements from CTD casts at two locations: (48° 25.40′ N, 70° 51.94′ W) and (48° 24.81′ N, 70° 47.53′ W).
2) NetCDF outputs from 2D idealized numerical simulations conducted using the MITgcm.
3) Temperature time series collected at 48° 24.107′ N, 70° 50.001′ W at various depths using 14 RBRsolo3 T temperature sensors and one RBRduet3 T.D temperature-depth sensor. The deepest instrument, positioned one meter above the seafloor, was the temperature-depth sensor. All time series are stored in a NetCDF file., , # Temperature profiles and idealized simulations of internal solitary waves colliding with the Grande-Anse wharf, Saguenay Fjord, Canada

## Description of the data and file structure

This dataset contains:

1\) The **CTD_data** directory which contains two CTD profiles taken in the vicinity of the Grande-Anse Terminal.

This directory includes:

* **CTD_far_field.mat**: A MATLAB file containing depth (*z*) in meters and density (*rho*) in kg m⁻³ from CTD measurements at two stations:
* Station A (48° 25.40' N, 70° 51.94' W) – variables labeled with the suffix *PMZA06*.
* Station B (48° 24.81′ N, 70° 47.53′ W) – variables labeled with the suffix *F14*.
* **read_CTD_mat.py**: A Python script designed to read the data from **CTD_far_field.mat**.

2\) The **MITgcm_runs** directory which contains three repositories with NetCDF outputs from 2D idealized simulations of four internal solitary waves collidi...
