For a portion of our crossing from Greenland to Iceland the waves rocked the ship to the point that some passengers became uncomfortable. The decks became slick with rain and snow, and for safety reasons we remained inside.
When the sea calmed down this Northern Fulmar and his brethren repeatedly skimmed the waves, apparently utilizing the ground effect to save energy while hunting.
I captured this image from our cabin's window using the 70-200mm zoom + the 2x converter to achieve the 400mm focal length needed to see the bird at a reasonable size in the image.
