With overcast conditions coupled with light winds, we were hopeful of a productive crossing. This was Tibor's first survey for MARINElife, so after a briefing and a bite to eat, we headed up to meet the bridge team and commence our survey.

Seabird numbers were down on last month, presumably due to their migration season having started. Initially we recorded just a handful of Kittiwake and Guillemot before a fleeting glimpse of the first of many Harbour Porpoise for the crossing.

As the survey progressed, other species of seabird were added to our list including a few Little Gull with the distinctive dark underwings showing nicely. We also recorded a couple of Fulmar gliding across the sea's surface.

With the French coast approaching, we entered an area with increased numbers of Harbour Porpoise, with several in quick succession followed by a few Red-throated Diver and a few groups of Common Scoter.

After a short turnaround, we headed out of Dunkirk for the return crossing. The area with Harbour Porpoise was quiet on the return but we did see a few Razorbill. As we headed further out, we picked up some groups of Lesser Black-backed Gull heading east and, with Dover in sight, we once again had a flurry of Harbour Porpoise encounters.

Passing Cote des Flanders as she headed out of Dover, we pulled alongside our berth and thanked the bridge team for another interesting crossing of the Dover straits.
