LAGOS Lake nutrient, carbon and chlororphyll data to evaluate biases in lake water quality sampling practices in a 17-state region of the US

This dataset includes data for eight major limnological variables in
LAGOS-NE_LIMNO v. 1.087.1 that were used to evaluate biases in lake
water quality sampling and implications for macroscale research
(Stanley et al. In Revision, Limnology and Oceanography). Most
observations came from LAGOS-NE_LIMNO v. 1.087.1, an integrated
database of lake ecosystems (Soranno et al. 2015, Soranno et al. 2017)
but were supplemented with additional data from the State of New
Hampshire. LAGOS-NE contains information on lakes great than or equal
to 1 ha (originally derived from the U.S. Geological Survey's 2013
National Hydrography Dataset) for a 17-state region of the U.S., and a
subset of the lakes has observational data on lake chemistry and
productivity. Approximately 87 different sources of data were compiled
for the LAGOS-NELIMNO v. 1.087.1 dataset and were mostly generated by
government agencies (state, federal, tribal) and universities. In this
analysis, we compiled data for eight major limnological variables
(Secchi disk depth, chlorophyll, total phosphorus, total nitrogen,
nitrate, ammonium, true water color, and dissolved organic carbon) and
geographic characteristics of lakes (location, lake area, depth,
perimeter, watershed area) to evaluate biases in different
limnological properties over space and time.
