Dissolved oxygen and temperature observations at a high temporal frequency and a broad spatial extent provide the supporting data for the development of experimental hypoxia hindcast and forecast models and aid our understanding of the development and extent of hypoxia. Underwater sensor moorings were deployed across the central basin of Lake Erie to monitor oxygen conditions by the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory and the Cooperative Institute for Great Lakes Research (CIGLR), University of Michigan. Moorings were deployed during the summer season beginning in 2017 to collect in situ data for the following parameters, water temperature, dissolved oxygen, water current speed and direction, specific conductivity, pH, turbidity, oxidation-reduction potential (ORP), chlorophyll, phycocyanin, dissolved organic matter, and phosphorus at hourly or sub-hourly time intervals. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

NOAA National Centers for Environmental Information custodian ADCP ADCP 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. buoy buoy generic type of floating instrumentation package buoy - moored buoy buoy - moored buoy a moored buoy does not measure anything. it is a platform for instruments, which do measure things. CTD CTD Conductivity-Temperature-Depth probe CTD - moored CTD CTD - moored CTD CTD - moored CTD mooring mooring use as an observation type multi-parameter water quality sensor multi-parameter water quality sensor used to measure temperature, salinity, dissolved oxygen, and other parameters Instrument used to measure temperature, salinity, dissolved oxygen, and other parameters, often used to measure water quality parameters. Can be a hand-held instrument or a sonde for unattended monitoring. Often used in coastal water monitoring stations. YSI is the preeminent brand (as of 2024). oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. PAR Sensor PAR Sensor 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.
