        abstract:  NOAA Great Lakes Environmental Research Laboratory collected the data from moored Realtime Coastal Observation Network (ReCON) Muskegon M20 Buoy (NDBC station 45161), Lake Michigan, an in-situ moored station, in the Great Lakes. Observations were collected during the open water seasons of 2009-2019. This station is also known as NOAA National Data Buoy Center (NDBC) station Muskegon Buoy, MI (45161). A temporal subset of these data are available from NDBC and the Great Lakes Observing System (GLOS) since 2012, this data accession contains the complete record of observations. The ReCON buoy provides continuous, real-time observations, facilitates modification of sampling parameters in anticipation of episodic events, facilitates the collection of field samples in response to episodic events, supports long term research, and contributes to sensor and system development. Parameters collected include currents, water temperature, other oceanographic parameters, and meteorological parameters. The block of text at the beginning of each file contains information about the location and sensor used to collect data and the data headers followed by the observed data. Column 1 of the data is the timestamp, column 2 is the observed data, and column 3, where applicable, the QARTOD flag. Five QARTOD tests were run including gross range, climatological, spike, rate of change, and flat line tests. The highest value from the five tests were included under the “Qartod” column. If data were known to be invalid, that line of data was removed from the dataset.
        purpose:  The goal of the ReCON project is to develop a national network of coastal buoys capable of seabed to sea-surface observations. This wireless Internet observation system, with shore stations at coastal locations covering approximately 800 square miles of sea surface, uses commercially available networking equipment allowing straightforward integration into a nationwide network. Each system collects meteorological data and provides sub-surface measurements of chemical, biological, and physical parameters. The system is designed to allow controlled access to multi-institutional users through surface buoys and sub-surface sensor guest ports located on an underwater hub. The observation network currently provides environmental data to state, federal, and university researchers, educators and resource managers.

            description:  Acoustic Doppler Current Profiler The Acoustic Doppler Current Profiler (ADCP) measures currents beneath a ship while underway. Sound signals sent from the moving ship bounce back to receivers aboard the ship. This provides a profile of water movement relative to the ship-precise modern navigation, allowing the ship's motion to be subtracted from the data. These devices are also used on moorings and profilers and, along with acoustic backscattering, measure animal biomass. Particles in the path of the sound waves, mostly plankton, reflect a small part of the sound energy back toward receivers, allowing researchers to make remote estimates of the sizes and numbers of animals present in the water column. Before the 1970's, the most technologically advanced instrument used to measure water velocity was known as a Doppler speed log. This evolved into the first commercial ADCP, produced in the mid-1970's, which used averaging. Later in the 1970's, the first vessel-mounted ADCP was developed to measure water velocity more accurately and to allow measurement in range cells over a depth profile. As instruments evolved, so did new techniques in Doppler signal processing. Initially, Doppler speed logs used simple analog signal processing methods, which are still used in some commercial speed logs today. However, the first ADCPs incorporated analog-to-digital signal conversion over a narrow communication bandwidth. Around 1990, this technique was developed into broadband signal processing. Since then, broadband ADCPs have been able to generate very accurate, real-time velocity measurements.

            description:  Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm)
