    "description": "This metadata record represents the R phytoclass package.\n\nDetermine the chlorophyll a (Chl a) biomass of different phytoplankton groups based on their pigment biomarkers. The method uses non-negative matrix factorisation and simulated annealing to minimise error between the observed and estimated values of pigment concentrations (Hayward et al. (2023) https:\/\/doi.org\/10.1002\/lom3.10541). The approach is similar to the widely used 'CHEMTAX' program (Mackey et al. 1996) https:\/\/doi.org\/10.3354\/meps144265), but is more straightforward, accurate, and not reliant on initial guesses for the pigment to Chl a ratios for each phytoplankton group.\n\nFurther details are provided at:\nHayward, A., M. H. Pinkerton, and A. Gutierrez-Rodriguez. 2023. phytoclass: A pigment-based chemotaxonomic method to determine the biomass of phytoplankton classes. Limnol. Oceanogr.
