notes: The relationship between total chlorin and temperature is NEGATIVE. Note that figure 4 in the study by Saunders et al (2013) is incorrectly labelled. The y axes for R_650;700 should be inverted and the correlation is negative (not positive as originally published). An erratum is in preparation.
