Due to a current name change, European ʻUlva lactuca L.ʼ is now recognised under the name Ulva fenestrata Postels & Ruprecht (Hughey et al., 2019). In this regard, the title of this publication should read “Chemical profiling of the Arctic sea lettuce Ulva fenestrata (Chlorophyta) mass- cultivated on land under controlled conditions for food applications”. Moreover, reference to the sea lettuce species in this study should be Ulva fenestrata throughout the manuscript. It is essential to push for the correct identification of the species because this has wider implications on the use of different species of sea lettuce for food.
