From: Holocene evolution of Portus Pisanus, the lost harbour of Pisa
Environmental-based clusters from the harbour basin for the last 8000 years. (A) A cluster analysis (paired group as algorithm, Correlation as similarity measure) was used to define the environmental assemblages (marine versus fluvial influence). (B) The two cross-correlograms (P = 0.05) depict the marine influence on ecosystems around the basin.
