Winter Community Structure Changes in Frazil Ice and Open Water in Riverine Systems

摘要

This technical note builds on previous work (White et al. 2001, White 2002, White and Melloh 1999) that examined dissolved oxygen (DO) levels and changes in river microbiology during winter, periods of low water temperature, and periods of ice-cover, with the objective of providing guidance for winter water-quality modeling. The results of this study provide information on riverine microbial abundance and diversity in ice-affected rivers and can be applied immediately to improve winter modeling using existing water quality models such as the Corps' CE-QUAL-W2.
