Environmental Evaluation of Pyropia Aquaculture Farm off Imja island in Shinan on the Southwest coast of Korea by Multivariate Analysis

For the data-based Pyropia cultivation further, we analysed the environmental data using a multivariate analysis of a Pyropia aquaculture farm off Imja island in Shinan, Jeollanam-do, Korea, from September 2019 to March 2020 for the first time. The pairwise simple correlation matrix among 13 seawater environmental variables was shown. The first three principal components explained 76% of the total sample variance. The first principal component(z1) showed the freshwater inflow and/or precipitation, the z2 related to nutrients, and the z3 eutrophication.
