The laboratory experimentwas carried out at the Alfred Wegener Institute in Bremerhaven, Germany.8.5805253.53327The Research Council of Norwayhttps://doi.org/10.13039/501100005416334327KELPRIME - Priming as a kelp engineering technology to enhance yield and secure production under environmental challenges
