Twelve intact sediment cores were collected from this site on the Western Treatment Plant foreshore (Port Phillip Bay, Victoria) and brought back to the laboratory. Four cores were assigned to each of three treatments, which were low dose (3.5mls effluent per minute), high dose (7mls effluent per minute) or no dose of effluent. The experiment ran for 14 days in October 1997. Throughout the experimental period, dissolved oxygen levels were measured and animals that migrated from the sediment were collected, counted and identified. At the end of the experiment, sediment chlorophyll levels were measured and infauna remaining in the sediment were counted and identified. {"type": "Polygon", "coordinates": [[[144.3, -38.3], [145.2, -38.3], [145.2, -37.8], [144.3, -37.8], [144.3, -38.3]]]} 144.3 145.2 -38.3 -37.8 22 002000 22 096000 24 486001 28 546000 28 551000 Biosphere | Aquatic Habitat | Benthic Habitat | soft sediment | mudflat Biosphere | Ecological Dynamics | Migratory Rates/routes | vertical migration Biosphere | Ecological Dynamics | Oxygen Demand | hypoxia Biosphere | Ecological Dynamics | Survival Biosphere | Zoology | Invertebrates Capitellidae Corophiidae Gammaropsis sp.
