A 1 X 1 kilometer (km) ARCSS/CALM grid was installed at Barrow in the early 1990s to facilitate collection of ecological, edaphic, and geocryological information at standardized locations that could be tied into coordinate systems with high-order accuracy. Simultaneous air and shallow ground temperatures observations have been made at several locations on the Barrow grid since 1993. The environment at Barrow was described in a series of papers including of the Tundra Biome Program during the 1970s. The Barrow 1-km2 grid is located about 5 km east of the village of Barrow on the outer Arctic Coastal Plain. The site is situated on reworked silts of marine origin. Terrain occupied by the grid encompasses a drained lake basin or lagoon to the west (Central Marsh). To the east is a polygonized ‘‘upland,’’ a term used here to convey relative elevation within the low relief Coastal Plain. These areas are separated by a north-south trending beach ridge composed of sandy gravels. The polygonized upland is occupied by moist acidic tundra, with well-developed low-centered, ice-wedge polygons in the northeast and high-centered ice wedge polygons to the southeast. The latter developed in response to thermomechanical incision by streams draining to Elson Lagoon in the southeastern corner of the grid; ephemeral flow is confined to the ice-wedge troughs.
