Velocity observations from a mooring at Station AT55 in Lake Michigan from 2019-05-13 to 2019-06-05

Abstract:

A fixed mooring was established to measure water column velocities in Lake Michigan near Milwaukee, WI, during 2019 from May 13 – June 5, 2019 at a 55m depth site. The mooring involved a small tripod, upon which an ADCPs (Nortek Signature 500) was mounted to measure water column velocities between 152cm and 4852cm above the bed.

Description

A fixed mooring was established to measure water column velocities in Lake Michigan near Milwaukee (12 km northeast of Milwaukee Harbor), WI, during 2019 from May 13 – June 5, 2019 at a 55m depth site. Site coordinates: 43o 4.195’ N, 87o 45.193’W.

The mooring involved a small tripod, upon which an ADCPs (Nortek Signature 500) was mounted to measure water column velocities between 152cm and 4852cm above the bed.

Methods & Sampling

ADCPs were used to sample current velocities at 2 Hz, with the Nortek Signature 500 (152cm - 4852cm above bed, 1m bin size) measuring continuously.

Data Processing Description

Data were successfully downloaded from instruments. No problems were detected with the measurements.

All velocity data was averaged over 10 minutes of sampling before being interpolated onto a common time vector. Individual instrument accuracies, ranges, and resolutions are included in the attached file (ADCP_METADATA_052019.xlsx).

All data were quality controlled according to manufacturer recommendations and measurements with poor amplitudes and correlations were removed before averaging.

Acoustic Doppler Current Profiler

Supplied Name: Nortek Signature 500

Supplied Description:

Nortek Signature 500

Instrument Type

Generic Name: Acoustic Doppler Current Profiler

Acronym: ADCP

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/115/

Generic Description:

The ADCP measures water currents with sound, using a principle of sound waves called the Doppler effect. A sound wave has a higher frequency, or pitch, when it moves to you than when it moves away. You hear the Doppler effect in action when a car speeds past with a characteristic building of sound that fades when the car passes. The ADCP works by transmitting "pings" of sound at a constant frequency into the water. (The pings are so highly pitched that humans and even dolphins can't hear them.) As the sound waves travel, they ricochet off particles suspended in the moving water, and reflect back to the instrument. Due to the Doppler effect, sound waves bounced back from a particle moving away from the profiler have a slightly lowered frequency when they return. Particles moving toward the instrument send back higher frequency waves. The difference in frequency between the waves the profiler sends out and the waves it receives is called the Doppler shift. The instrument uses this shift to calculate how fast the particle and the water around it are moving. Sound waves that hit particles far from the profiler take longer to come back than waves that strike close by. By measuring the time it takes for the waves to bounce back and the Doppler shift, the profiler can measure current speed at many different depths with each series of pings. (More from WHOI instruments listing).
