Anoxic events are a common occurrence in Island estuaries during the summer months. The symptoms of an anoxic event include:
- milky white or green discolouration of the water,
- H2S or 'rotten turnip' odour, and
- low (near zero) dissolved oxygen readings.
A list of sites that have recorded anoxic events in 2014 is provided below. A map of these sites is available. A map that highlights the intensity of anoxic events across PEI from 2009 to 2014 is also provided.
Historical information, from 2004 to 2013, is available.
Please note that information provided may not capture every anoxic estuary in PEI for a particular year. Some events may not have not been reported to, or documented by, the Department of Environment, Labour and Justice.
