Hi,

Mr Godwin

Helena Santiago Lima

Hello Mr Godwin I think the simplest software to perform this type of analysis is PAST (https://folk.uio.no/ohammer/past/ ), because its interface is very friendly. As you want to add some physicochemical parameters in the analysis, I recommend that you do a CCA. Any questions can contact me. Good luck!
