Methods & Sampling

This dataset contains the excitation emission matrix data from solid-phase extracted (Agilent Bond Elut PPL).

Water samples were collected using the ship's CTD profiler and 12 L Nisking bottles. 10 L water samples from each depth were then transferred into 5 gallon polycarbonate water bottles and extractrated.

The solid-phase extracted methanolic sample was dried (0.5 mL of methanolic extract) under nitrogen and re-dissolved in 5 mL of pure water prior to fluorescence analyses. All fluorescence data were normalized to the water raman scattering (RU).

Data Processing Description

The raw fluorescence data was scatter corrected and the processed using the Matlab-based DrEEM toolbox and Parellel Factor Analyses (PARAFAC) developed by Kate Murphy.
