About

In this repository you will fine a geospataila analysis identifying optimal location for Marine Aquaculture development along the West Coast of the United States. To determine areas more suitable for Oyster farming and other marine aquaculture operations, we evaluated Exclusive Economic Zones (EEZs) based on species specific Sea Surface Temperature (SST) and Depth requirement.

Objective for this assignment:

  • Combining vector/raster data
  • Resampling raster data
  • Masking raster data
  • Map algebra
  • Creating a function

About Data:

Sea Surface Temperature

Use average annual sea surface temperature (SST) from the years 2008 to 2012 to characterize the average sea surface temperature within the region. The data was originally generated from NOAA’s 5km Daily Global Satellite Sea Surface Temperature Anomaly v3.1.

Bathymetry

For ocean depth characterization use the General Bathymetric Chart of the Oceans (GEBCO).3

Exclusive Economic Zones

To designating maritime boundaries use Exclusive Economic Zones off of the west coast of US from Marineregions.org.
