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 during 2019 is provided below. A map of these sites is available and Historical information, from 2009 to 2018, is available. A map that highlights the intensity of anoxic events across PEI from 2014 to 2018 is also provided.
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.
