Fluorescence Line Height (FLH) andFluorescence 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, 1/2003-12/2007 (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”

Percentiles (units of m-1)
*wrt in situ data, "shallow" refers to the PnB dataset, while "Deep" reflects the OSU dataset. Otherwise they refer to depths <100m and >1000m, respectively
