Replication Data for the Lake Sentinels sampling program: water chemistry, phytoplankton, zooplankton, and profiling data for three Quebec lakes from fall 2012-2015

Data were collected every two weeks in summer and every four weeks in winter beginning fall 2012 and ending fall 2015 in the Quebec (Canada) lakes Lac Croche, Lac Montjoie, and Lac SImoncouche. On each sampled date, a temperature profile was taken and analysed to determine if the lake was stratified or not. When stratified, discrete samples were taken for chemical and biological analyses in both the epilimnion and the metalimnion. When mixed, discrete samples for chemical biological samples were taken from one depth within the mixed layer. Profiles of lake oxygen, temperature, conductivity, and pH were taken, as were profiles of phytosynthetically active irradiance (PAR).
