Inferred spring discharge characteristics of the Saguenay River, Quebec between ca. 1850 and ca. 1900 based on sediment texture proxy data [electronic resource] / C.T. Schafer. [Ottawa] : Natural Resources Canada, 2017. 52 p. : chart, ill., map. Open file ; 8190 Includes bibliographical references. “This study explores the potential of sediment textural variation as a proxy for spring freshet magnitude variation of the Saguenay River using fine sand to fine silt fractions that have been preserved in Saguenay River prodelta sediments deposited in the northwestern sector of the Saguenay Fiord’s North Arm. A particle size (2.3 to 6.3 phi i.e., 0.220 mm to 0.013 mm) median diameter (MD) proxy of spring freshet magnitude determined at one cm intervals in a piston core collected in 1982 reflects year-to-year variability of the River’s spring freshet magnitude during the 19th and most of the 20th century. This study focuses on the second half of the 19th century during which MD data records an estimated 19 year long interval of relatively small MD’s (LMDI) that is estimated to have occurred between 1871 and 1888”--Abstract, p. 3. gccst Rivers gccst Sediments gccst Hydrology gccst Surfical geology gccst Geochronology Saguenay River (Québec) Canada.
