Prioritizing Potential Aquaculture in West Coast EEZs

Author: Emma Bea Mitchell

Purpose of the repository:

The main purpose of the repository is to create a function that can use depth and sea surface temperature data to find suitable locations in EEZs for marine aquaculture. To do this we:

• Reclassify depth and sea surface temperature data into suitable and unsuitable locations
• Find suitable locations based on EEZs
• Map EEZs by amount of suitable locations

Function arguments:

• minimum and maximum sea surface temperature
• minimum and maximum depth
• species name

Function outputs:

• map of EEZ regions colored by amount of suitable area

Skills utilized in this project:

• map algebra
• function creation
• changing raster extent, resolution, and crs
• map creation using tmap
