2001 Upper Mississippi River Pool 8 Rake Study Data Set.

The Yin et al. 2000 rake method is used by researchers in the Upper Mississippi River Restoration Program to estimate the distribution of submersed aquatic vegetation on the Upper Mississippi River System. Biomass data were collected in 2001 to assess if the Yin et al. 2000 method could be used to estimate biomass based on the rake density ratings. Sediment samples also were collected to measure sediment nitrogen availability and particle size.
