| Notes | What happens when sediments from the Umpqua River are deposited in the ocean? The answer to this question for the Umpqua and other rivers is important to understanding the global carbon cycle. Although the author of this thesis thought at first that the Umpqua's sediments would be widely dispersed by ocean action, she learned that instead, they are concentrated in one location, which she terms "a mid-shelf depocenter." Despite the energies of ocean tides and currents, this area is not swept clean, and sediments continue to accumulate. The author finds evidence that "suggests that other low-sediment-yield rivers may also create depocenters." (p.47) |
