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

Abstract:

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.

Description

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

On 2019-04-08 an update was received for this dataset. This update contained an extension of the data for 2018.

Data Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming convention
- combined YEAR, MONTH, DAY, HOUR, MINUTE, SECOND columns into one ISO_DateTime_UTC column.
- removed columns YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND
- added lat, and lon columns.
- extracted height above bottom from column headings in submitted data file.
- reorganized the data file to have one column for depth and one column for temperature
- sorted data by depth, then ISO_DateTime_UTC.
