The First basking shark sighting of the year was recorded on 28 February, 350km southwest of Ireland during the Cetaceans on the Frontier Cruise III. It was spotted just 50m off the bow of RV Celtic Explorer at 11.30 in the morning. This early in the season, a basking shark sighting this far offshore is rather unusual and provides valuable data on basking shark distribution patterns. From archival tracking studies we know that basking sharks show extensive migrations across the Northeast Atlantic, thereby frequently moving along the Continental shelf edge.
