This dataset contains chemical, optical, and physical data collected on R/V Neeskay and R/V Osprey during cruises Neeskay_Cruise_1 and Osprey_Lake_Michigan_2017 from 2017-05-11 to 2017-11-13. These data include O2 saturation, PAR, beam attenuation, conductivity, depth, dissolved Oxygen, pH, water pressure, and water temperature. The instruments used to collect these data include CTD Sea-Bird 25. These data were collected by Dr Harvey Bootsma and Dr Qian Liao of University of Wisconsin as part of the "Collaborative Research: Regulation of plankton and nutrient dynamics by hydrodynamics and profundal filter feeders (Filter Feeders Physics and Phosphorus)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-03-15.

The following is the text of the dataset description provided by BCO-DMO:

Dataset Description:
CTD data collected in 2017 from Lake Michigan, depth = 55-75 m, approximately 12-16 km northeast of Milwaukee Harbor.

Supplemental Information
Acquisition Description:
Data were collected using a SeaBird SBEplus 25 CTD, calibrated annually by SeaBird.

Data are processed using the "SBE Data Processing" software package provided by Sea-Bird Scientific. The processing modules used were as follows:

Data Conversion. Potential temperature anomaly set to 0. Tau correction is applied to dissolved oxygen measurements, with a 2-second window.

Filter. Low pass filter A time constant = 0.1 seconds. Low pass filter B time constant = 0.5 seconds.

Align CTD. An advance value of 0.1 seconds was applied to conductance measurements, and an advance value of 5 seconds was applied to dissolved oxygen measurements.

Loop Edit. Minimum CTD velocity set to 0.1 meters per second. Scans marked bad are excluded.

Bin Average. Bin type = Depth. Bin size = 0.25 meters. Both the upcast and the downcast were processed.
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
