The use of multivariate statistical analysis in lipid biomarker studies

Fatty acids, fatty alcohols and sterols have been determined for a sediment core taken from the Conwy Estuary, United Kingdom. These biomarkers were used to identify temporal variations in organic matter sources within the estuary. Principal Component Analysis (PCA) was used to distinguish the domin...
