Lake Mendota Microbial Observatory Secchi Disk Measurements 2012-present

Abstract

The Lake Mendota Microbial Observatory collects routine water clarity measurements
alongside their microbial samples. This dataset includes measurements of water clarity
collected at the central Deep Hole, collocated with a weather buoy (43°05'58.2"N
89°24'16.2"W). All measurements were collected with handheld Secchi discs. When multiple
personnel performed the Secchi disc measurements, the average and standard deviation are
reported. To take the Secchi depth, sunglasses are removed and the disc is lowered on the
shaded side of the boat. The Secchi depth is the average between where the Secchi disc
disappears while lowering it and where it reappears while raising it. Routine microbial
observatory sampling continues into the present.<br/>
