There were delays at the port on our arrival, however DFDS Office staff kindly managed to resolve these for us and we boarded the ferry almost on time. There were plenty of "white horses" as we started the survey and our first bird sightings were Kittiwake and Great Black-backed Gull, followed by regular sightings of Gannet.

Around an hour into the survey we spotted the first Sandwich Tern. These were the most common sighting of the day, all no doubt, on passage to their winter destination off the west coast of Africa. Around half an hour later, closer to the French coast a Great Skua was spotted off to starboard. A minute or so later we had a good view of an Arctic Skua in light phase, plus another one slightly further away.
Ten minutes later on the approach to Dunkirk harbour we spotted our first sea mammal, a Grey Seal, loitering almost in front of us. The Captain advised us that he had seen quite a few seals in the area recently. This statement was borne out later on our return trip, when we had four further sightings, all of Grey Seal.

The cetacean sightings of the survey, both of Harbour Porpoise were not seen until we approached the Kent coast. The bird sightings were similar to those surveyed on the outward leg: Great Black-backed Gull, Kittiwake, Gannet, Sandwich Tern and Mediterranean Gull, with Black-headed Gull and Cormorant seen in Dunkirk harbour.
We would like to express very warm thanks and gratitude to DFDS office staff, plus Captain Mills and crew for their support during the survey.
