Fluorescence Line Height (FLH) and Fluorescence Quantum Yield (FQY)

Fluorescence Line Height (FLH) -Histograms of individual monthly L3 composites, 7/2002-2/2010 (black dotted lines) -Mean of individual distributions = distribution of all data pooled together (red line) - Distribution of “deep water” data nearly identical to all data (small differences at high end) - Shallow water distribution shifted towards higher values (as expected)

Fluorescence Quantum Yield (FQY) -Histograms of individual monthly L3 composites, 1/ /2007 (black dotted lines) -Mean of individual distributions = distribution of all data pooled together (red line) - Distribution of data somewhat independent of depth. In fact, median “deep water” value is slightly higher than “shallow”
