SHARKS

Published portfolio: https://www.iannorstad.com/sharks

An ongoing exploration of shark attacks (encounters/ incidents) from 1959- 2018. The focus is primarily on California, and how the state compares to other high risk areas around the globe.

Using the Global Shark Attack File I was able to address specific questions I have about the occurrence of shark attacks in California. These questions are:

• Are shark encounters increasing or decreasing?
• Where are the places with the highest rate of encounters?
• How does population play a role in reports of shark encounters?
• How does seasonality play a role in encounters?
• Is Northern California, especially the Red Triangle really that much more dangerous than the rest of California?

Data Source

The primary data source used for this project was sourced from the Global Shark Attack File:

https://www.sharkattackfile.net/incidentlog.htm

This dataset has been collected by the Shark Research Institute and contains records going back to BC times. I chose to filter the data from 1959-2018 on most of the plots I created because that is a significant range that can be considered both modern and recent, and seems to have reliable record keeping. Surfing also surged in popularity during this period, which I felt was especially relevant for this project.

Census data came from here (no API key needed:)
