Cover title. Includes bibliographical references (page [6]). "The summary indicator of the temperature of the three water layers in the Gulf of St.Lawrence (surface, intermediate and deep), together with the hypoxic conditions and acidification of the estuary, was at a Moderate rating during the 2013-2017 period. A deteriorating overall trend was nonetheless observed relative to the 2008–2012 period, mainly because of temperatures in the deep-water layer that have reached record levels in time series that begin in 1915.
