2020 Map of Barrow A-1 NW

About this map

Beaufort Sea waters dominate this coastal Arctic landscape on the edge of the North Slope. The map documents a fragile coastal geography where the sea meets a series of barrier islands and landforms. Among these are the Plover Islands and Tulimanik Island, which sit south of Igalik Island in the open waters. The presence of Tangent Point and Kulgurak Island along the shoreline illustrates the transition from the mainland to the marine environment. This survey provides a baseline of the shifting northern coastline, tracing the exact positions of these remote islands and landforms as they existed in the early 21st century. The map is primarily an aquatic and coastal study, focused on the nautical boundaries where the northernmost reaches of Alaska encounter the sea.
