Bottom fauna distribution

Repeating observations and analyses at two sampling stations in Kanholmsfjärden during 2010, 2011 and 2012 showed relatively small differences in the bottom fauna distribution. The oxygenation that occurred had obviously not worked long enough to affect the sediments. Observation in other oxygenated coastal regions however, indicated a colonization of benthic invertebrates in previously anoxic bottoms after three years of oxygenation.
