Present and past hydroecology of the Old Crow Flats, YT, 2007-2011
Water samples are being collected from ~50 basins and 13 river locations at three time steps during the thaw season for analysis of water chemistry, stable isotope composition, total suspended sediment concentration, phytoplankton and zooplankton. Sampling began in 2007 and will continue through 201...
