NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. CTD CTD Conductivity-Temperature-Depth probe 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.
