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 2018 is provided below. A map of these sites is also available
Historical information, from 2008 to 2017, is available. A map that highlights the intensity of anoxic events across PEI from 2013 to 2017 is also provided.
