Modelling Salmon Life Cycle in Comox Valley Harbour

Project description

Our goal is to model the life cycle of chinook salmon. We are interested in studying the long term impact of population size of salmon when we introduce microplastic ingestion, as well as fishing and harvesting practices. We are also interested in studying the differences in long term chinook salmon population changes resulting from two fishing models: industrial fishing and intertidal modifications (which rely on tide behaviour) used by the Northern Coast Salish Peoples.

How to use code in this repository

This script contains code that scrapes data from the following website https://www.waterlevels.gc.ca/eng/data for a given location.

We will focus on data from Comox Valley Harbour.

The python script will take as input: Website URL Start date (Year-Month-Day) End date (Year-Month-Day) And as output it will return a pandas dataframe (or a CSV) with the data with the following columns:

Date (YYYY-MM-DD) Time (24 hour format) Height-of-tide (meters)

Sample script usage

python3 scrape_tide_data.py URL start_date end_date
