Island Pond High Resolution Temperature Monitoring

The water column of Island Pond was weakly stratified when sensors were deployed. Surface water temperatures increased gradually until reaching peak temperature of 30.9 °C (87.6 °F) in mid-July. Surface water cooled slightly in late July and warmed again in early August before beginning a gradual decline that persisted for the remainder of the season. Shallow waters began to cool and mix with waters from the middle depths in early September. 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.
