  1. Benthic core samples were from three mid-lake locations (WH1, WH2 and WH3) collected in July 2015. Total benthic pigment stocks per unit area are given for comparison with phytoplankton values integrated for the overlying water column at each site.
  2. aIntegration using the mean concentrations from three samples at each of the two depths: 2.2 and 7.5 m.
