GEOMORPHOLOGICAL (landform) DESCRIPTION OF AREA CONTAINING SITE:
Grid site is west of Otuk creek therefore draining into Otuk creek. Ivotuk is on the north side of the Brooks range. Area topography is shallow.

PERMANENT TEMPERATURE AND/OR MOISTURE INSTALLATIONS (probes, recorders, sensors, etc.); INCLUDE ANNUAL AVERAGE VALUES/RANGES WHEN POSSIBLE: Air temp, soil moisture and soil temperature along with other meteorological sensors.

CLOSEST CLIMATE STATION (name, lat./long.); INCLUDE MONTHLY AIR TEMP. AND SNOW DEPTH FOR YEARS OF CALM MEASUREMENTS: Met Site 1 (10 meter tower) and Met Site 2 (3 meter tower).

ADDITIONAL COMMENTS: This is a 1km by 1km grid marked at the perimeter and within the perimeter every 100 meters. We walked it along the north south aspect taking depths approximately every 25 meters.
