This dataset is a result of Random Forest modelling to predict cyanobacterial biovolume in lakes nationally, which included spatial modelling of chlorophyll a, TN, TP, Secchi depth, Trophic Level Index, and Cyanobacterial biovolume.
More information about the methods used to create this dataset can be found here: www.mfe.govt.nz/publications/fresh-water/strategic...
LID - FENZ Lake ID
Name - Name of lake (where available)
RegionalCo - Regional council name
CHLA - Chlorophyll a (mg/L)
TN - Total nitrogen (mg/m3)
TP - Total phosphorus (mg/m3)
SECCHI - Secchi disc depth (m)
TLI3 - Trophic Level Index (unitless)
CyanoBioVo - Cyanobacterial biovolume (mm3/L)
