Influence of a changing wave climate on the quality and morphometry of the stalked barnacle (Gmelin, 1789), along the coasts of NW Iberia.

Unlabelled: Wave climate is shifting over the last decades along the Atlantic coasts of Europe ultimately driven by large-scale patterns of atmospheric variability forced by anthropogenic global warming. Changes in wave height and surf zone orbital currents are hypothesized to drive marked shifts in the shape of intertidal organisms such as the stalked barnacle , whose quality and market price are known to decrease non linearly with the peduncle length: width ratio S. This study evaluates wave trends in NW Iberian Peninsula, using the Spanish Port System 2006-2020 SIMAR wave hindcast.
