Some bodies of water also appear in off-white or yellowish, probably due to different amounts of sediment in the water and/or the sun angle. The Beaufort Sea is at the top of the scene.

Teshekpuk Lake (Iñupiaq: Tasiqpak) is a 22 miles (35 km) wide lake on the Arctic coast of the U.S. state of Alaska, South of Pitt Point, 12 miles (19 km) east of Harrison Bay, 80 miles (130 km) east of Point Barrow.
Etymology
Its name comes from the Iñupiaq language Tasiqpak, recorded by Rochfort Maguire as Tasok-poh in 1854, and reported to mean "big lagoon", "big enclosed coastal water" or "big coastal lake".

Environment
Teshekpuk Lake is the largest lake in Arctic Alaska, the largest thermokarst lake in the world. Fish species in the lake include broad whitefish (Coregonus nasus), Arctic grayling (Thymallus arcticus ), Burbot (Lota lota ), Arctic cisco (Coregonus autumnalis ), lake trout(Salvelinus namaycush ), Dolly Varden (Salvelinus malma ), Chinook salmon(Oncorhynchus tshawytscha) and chum salmon(Oncorhynchus keta). The region provides habitat to a variety of arctic wildlife, including the Teshekpuk Lake Caribou Herd (64,000 animals), and large numbers of shorebirds and migratory waterfowl. The Teshekpuk Lake Observatory was established by the U.S. Geological Survey, National Science Foundation and other partners to study impacts of climate change on the arctic environment.
In July 2007, a study reported that the disappearance of sea ice near Teshekpuk Lake is causing rapid erosion in the marshy, wildlife-rich area. In some places, the sea has pushed in half a mile and salt water has contaminated freshwater lakes. According to the study, migratory birds, caribou and other wildlife populations have lost habitat, and the sparse human infrastructure along the coastline has been damaged. According to Stan Senner, executive director of Audubon Alaska, "The area (Teshekpuk Lake) is one of the most important areas in the entire Arctic, and I don't just mean in Arctic Alaska...It is simply the most important goose-molting area in the Arctic."
