Dataset: Temperature mooring data collected at Station AT55 in Lake Michigan from August 1, 2017 to April 20, 2018.

A fixed mooring was established to measure water column temperatures in Lake Michigan near Milwaukee, WI, from Aug 1 – Aug 17, 2017 at a 55 meters depth site and again during 2018 from April 5 – April 20, 2018. The mooring involved a large tripod to which a surface line was attached and along this line were temperature sensors at various depths. Depths may vary slightly due to unmeasured chain drift.

All temperature data collected during 2017 were smoothed using a 2s moving average before being interpolated onto a 2s sampling interval. All missing data is represented by NaN.

All temperature data collected during 2018 were smoothed using a 1s moving average before being interpolated onto a 1s sampling interval. Individual thermistor accuracies, ranges, and resolutions are included in the attached file

Instrument Manufacturers: Sea-bird Scientific (SBE56); RBR (RBR TDR- 2050, RBR TR-1060); Onset (HOBO)
