Once we had departed, we headed to the bridge of the Delft Seaways to commence our survey. The outlook was a little gloomy with a sea state of 6 but, with the wipers on, we had relatively good vision ahead despite the rain.

The flurry of gulls in the harbour were soon left behind, but seabirds remained fairly constant throughout the crossing with Guillemot, Gannet and Kittiwake predominating.
Our first marine mammal came about 15 minutes into the crossing with a Harbour Porpoise sighted ahead of the ship, this was shortly followed by a pair of Grey Seal which looked at the ship as we moved passed them before diving.
Harbour Porpoise (Thomas Fisher)
Seabird diversity increased with a sighting of a Fulmar riding the waves followed by a Great Skua flying powerfully across the bow. More Harbour Porpoise were sighted as we headed fully into the English Channel and another Grey Seal as we neared the French coast.
After a brief stop in Dunkirk, we headed back out into the Channel and, although the rain had now stopped, the overcast conditions and mist continued to make more distant sightings difficult to pin down. We did manage a further seven Harbour Porpoise sightings on the return and further species of bird including a couple of Great Crested Grebe not far outside Dunkirk harbour.
Great Crested Grebe (Thomas Fisher)
A frenzy of feeding Gannet, Kittiwake and Guillemot indicated that some marine mammals could be present but we did not see them.
With darkness almost upon us, we headed into Dover harbour where we thanked the bridge crew of the Delft Seaways for making us feel so welcome.
