I've done some minor updates to the scripts. 
A few issues I'm having:

-I don't have the variables automated, so when more variables are added, the scripts have to be modified by hand, both the Environmental_Variables_Extract.R and Predict_GAMM.R (minor fix needed for this one). I could use some help with the input on it, maybe insert a function at the beginning to only download variables that are called? It's something I need to work on or will need help with. 

-still need to get all the variables input, as well as fix the sources for some of them, particularly AVISO. I'll be working on that next because nothing I've tried yet is working.
