Description: 

Dissolved organic Nitrogen (micromolar). DON was determined by subtracting PON and DIN (NH4, NO3-, and NO2-) values from TN values. Individual data points were deleted if the coefficient of variation remained greater than 15% after removing data points greater than one sd from the mean. Various points were deleted if the sample value was determined to be below the detection limit. If PON data were missing, DON values were left in if they met the following criteria:
sample depth was > 50m and surrounding values were less than or equal to 10% of the DON values. Other DON data were deleted if values were abnormally high or low according to the depth profile or expected ranges.
