Since the River Continuum Concept (RCC) was proposed in 1980, many studies and theories have been formulated to predict and measure how river biogeochemistry changes from the headwaters to the main stem of a river. Headwaters are an important part of river networks because they comprise a large proportion of the network and much of the biogeochemical processing of rivers occurs in them. To examine variability of biogeochemical processes in four Fraser Experimental Forest headwater streams, we used in situ sensors to take longitudinal measurements of pH, dissolved oxygen, colored dissolved organic matter, nitrate, and specific conductivity and compared these measurements from sensors at a downsteam fixed site. The values of all measurements varied for each stream, but we found similar longitudinal trends among three first order streams.
