Mayo, a small population of Laminaria ochroleuca Bachelot de Pylaie was discovered in a semi-protected cove on the northwest part of the headland among a mixed macroalgal assemblage including the kelps Laminaria digitata and Saccharina latissima. This is the first record of this southern European species in Irish waters.

Divers returned to Scots Port on September 13th, 2018 and collected small portions of the L. ochroleuca blades near the apical meristem. Samples from 15 individuals were wiped clean of epiphytic diatoms and filamentous algae, preserved in silica gel, and shipped to the Krueger-Hadfield Lab at the University of Alabama at Birmingham (UAB) for genetic identification and diversity analyses. This data has been reviewed against the DASSH Quality Assessment Criteria (http://doi.org/10.17031/64ccec5c7ba72) and been categorised as high-medium quality.
