South of the island, there is a polynya that extends 3 to 12 nm south that has begun to fill in with new (0 to 4 inches thick) and young (4 to12 inches thick) ice, then there is an area 8 to 14 nm wide of very close pack ice that includes primarily big to vast floes up to 28 inches thick. South of this area is an area of close pack ice up to 20 nm wide with strips of ice. To the west and north of Gambell, there is very close pack ice consisting of new ice then an area of very open pack ice beyond that. To the north of Savoonga, very close pack ice extends 2 to 4 nm from shore, then there is an extensive area of close to very close pack ice.

Forecast Discussion

Ice Forecast

As winds gradually shift around to the west and north, the very mobile ice pack surrounding St. Lawrence Island will drift to the east and then so the south. This will result in a polynya forming on the east side of the island, then on the south side of the island. As colder air moves southward early next week, new ice will likely form within many of the open water areas within and near the ice pack.

Observations and Comments

Observations of Sea Ice Development

Observations from Savoonga

29 March 2018 – Aqef Waghiyi

There’s ice out there about five miles out maybe. A couple of boats got walrus. Better weather this week. Took pictures from on top of the cliffs and from town and took a few videos. Will send those soon.

Observations from Gambell

29 March 2018 – Clarence Irrigoo, Jr.

Three or four boats went out today and I never go see what they got, it started snowing. This morning I saw about 4 herds of walrus on the ice and the boats never went to see them, kinda windy and start snowing heavy. Yesterday I think couple boats went out and got some bearded seals and one boat was going after a small whale and I guess they never see it again. The ice is near the land is slush and about a mile out is thicker not very big.

Observations from Wales

29 March 2018 – Robert Tokeinna, Jr.

This week I've had the opportunity to look on the southeast side of Cape Mountain. The ice seems to be in cakes and chunks other than broken up into pieces. This week it started out windy, snowy and ended with warm, southerly winds. Temperatures were in lower single digits to lower 30s. One local hunter walked to the edge of the ice and seen a number of seals and whales. Another local resident has seen snow birds which are signs of turn of the season from winter to spring. I have noticed during our warm up this past Monday of overflow on our creek that runs in middle of town. Still no full open water but some open leads as seen in the pictures. This ends my report.
