NOTES alongside a large ice floe about 2 km away. Initially, conditions were foggy with visibility limited to 200 m or less. Later it cleared, but there was heavy snowfall, and, by 16:30, a pallid sun appeared through the mist. There was virtually no wind, and the mean air temperature was 0°. The ship remained at the site until 17:30 (Moscow time); no birds were sighted while the vessel was stationary near the Pole. A ringed seal (Phoca hispida) made a brief appearance in the open water behind the vessel. Two of the ship's domestic animals were brought onto the ice.At 18:15 a black-legged kittiwake (Rissa tridactyla) was spotted at 89°58.9'N, 74°58.5'E, flying north. By this time, the sky was partially clear and visibility was at least 3 km. The adult-plumaged gull flew within 100 m of the slow-moving ship and proceeded along the channel through the ice made by the icebreaker over the Pole. There can be little question that the gull flew directly over the Pole.Icebreakers going to the North Pole possibly influence bird distribution. North of Zemlya Frantsa-Iosifa, large numbers of black-legged kittiwakes and some northern fulmars often followed the ship, presumably feeding in the open water of the resulting channel. As the vessel crashed through the ice, small fish (5-8 cm) were swept onto the surface. The kittiwakes immediately swooped down and consumed them. The broken ice probably also brought other food to the surface that would normally be inaccessible to the birds. The lower surface of the young ice, as well as the multi-year ice broken and over-turned by the ship, was often yellowish in colour, presumably a result of diatomaceous growth. Dark stringy algae were also observed in the ice below water level and on the bottom of overturned ice. Such growth was observed as far as 90°N. Thus, opportunistic birds encountering the partly open water of the icebreaker channel might follow it, ultimately being led to the Pole. These considerations cannot apply to submarines or aircraft, however.
