Methods and protocols used in the collection of this data package

Description:

Methods are described in Wilkinson et al. 2018 (Ecological Monographs 88:188-203) and Pace et al. 2017 (Proceedings of the National Academy of Sciences USA 114: 352-357). These publications including supplements should be consulted for details.
In Paul, Peter and Tuesday lakes two sondes were deployed at 0.75 meters near lake center. One sonde was a Hydrolab (model DS5X) with temperature, oxygen, pH, phycocyanin, and chlorophyll a sensors.  One sonde was a Yellow Springs Instruments (YSI) 6600-V2-4 with temperature, dissolved oxygen, pH, phycocyanin, and chlorophyll a sensors. Measurements were made every five minutes. Brief gaps in the data record due to calibration or sensor malfunction were interpolated using a bivariate autoregressive state-space model with the MARSS package in R version 3.9 to create a continuous daily time series.

Description:

Chlorophyll a concentrations are values reported by the instrument and were not calibrated relative to in situ values. We noted that when phytoplankton biomass increased dramatically due to nutrient additions that chlorophyll a concentrations from the two sensors did not conform to increases measured using manual methods (phytoplankton concentrated on filters from water samples where chlorophyll was determined fluorometrically after extraction).  Users of this data should be aware of this problem and use the chlorophyll values with caution.

Description:

Oxygen saturation was determined from measured concentrations and the function o2.at.sat available in the R package LakeMetabolizer (see https://rdrr.io/cran/LakeMetabolizer/man/o2.at.sat.html).
