Replicate (n=6 per treatment) 2.5 m by 2.5 m plots were dosed 4 times a week for four years with a mixture of seawater and fresh river water (15 psu salinity) to simulate the effects of long-term sea level rise (Press plots). Pulse plots received brackish water four times a week annually for four years during typical low flow conditions (September and October) to simulate the effects of drought. Separate replicate plots were dosed with fresh river water (Fresh treatment) to simulate the effects of submergence. This presentation will show major results from the four year long experiment, including responses of nutrients, plant species composition, biomass, green house gases, benthic algae, and surface elevation, to elevated salinity with different doses. |
