    dct:description "This dataset includes Gross Primary Production (GPP) estimates at 46 agricultural streams around the United States. GPP values are based upon the single-station dissolved oxygen method with data collected at 5-min intervals over a 24-hour period. GPP data is presented as grams dissolved oxygen per meter square per day." ;
