Mesocosms 2 by 2 Salmon Carcass and Wood Experiment

Mesocosms 2 by 2 Salmon Carcass and Wood Experiment

InPort Dataset ID: 17858

InPort Entity ID: 36828

This data contains analytical results from a 2 by 2 factorial experiment where salmon carcasses or small wood were added to stream mesocosms. Experiment conducted over a 45 day period summer 2007. Experimental streams were located along the bank of the Cedar River near Landsbug Dam, WA. Included in this table are data on water chemistry and benthic invertebrates colonizing unglazed ceramic tiles. The experiment was designed to test the effects of adding 0.6 kg/m2 of carcass tissue and small wood on water chemistry and invertebrates. Water chemistry samples were analyzed at the Oceanography lab, University of Washington. Benthic invertebrates were identifed to family or order using a dissecting scope.
