Bear Pond High-Resolution Temperature Monitoring

A. The water column of Bear Pond was weakly stratified when sensors were deployed in early May. Shallower waters gradually warmed until a slight, short cool down in early June. Temperatures of deep waters stayed consistently cold until mid-August.
B. Surface water temperature increased steadily from early June throughout July with peak temperature occurring on July 25 (26.3°C/ 79.3 °F).
C. Surface waters began cooling slightly throughout August but responded to a late season heat wave by reaching near peak temperatures in early September. Deep waters began to warm slightly but stayed cool enough to maintain strong stratification.
D. Shallow waters began to cool and mix with waters from the middle depths. Deep waters were still cold but continued to warm slightly.
E. Temperatures throughout the water column were becoming more uniform but temperature differences in the deep waters indicate that full mixing had not yet occurred when sensors were retrieved in late October.
