title: 'phytoclass: Estimate Chla Concentrations of Phytoplankton Groups'
version: 2.0.0
doi: 10.32614/CRAN.package.phytoclass
abstract: Determine the chlorophyll a (Chl a) concentrations 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 phytoplankton
  groups.
