Columbia River Ecology (769 words)
Duxbury et al concluded that their hypothesis was correct; single, periodic samples of the water at the mouth of the Columbia River were not representative of time or space, because levels of salinity, silicate content, and nitrate and phosphate levels can vary greatly in one place over a short period of time.
While it is interesting to note that the Columbia River's level of discharge affects how long it takes for the river water and the ocean water to mix, this phenomenon tells us very little about the river itself.
Thus, since the river has been converted from a spring and summer high flow river to a winter high flow river by dams, I would suppose that the mixing sequence found in this experiment is directly the reverse of what would have been found before the dams were built.
