      <gmd:abstract>
        <gco:CharacterString>Arctic Ocean primary production data were assembled from original input data archived in various international databases, provided by individual investigators or in publications. The data were collected by various methods and resulted from the efforts of many individual, national and international research efforts conducted between 1954 and 2007. Station data (cruise, station, latitude, longitude, depth), discrete data for productivity and chlorophyll a (value, method, phase, incubation type and length), photosynthetically available radiation (PAR) (incoming, integrated over incubation period), some integrated parameters, and some hydrographic parameters (nutrient concentration, mixed layer depth) as well as source (investigator, data base, publication, etc.), if available, were included.</gco:CharacterString>

            <gco:CharacterString>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.
