File <1995-2001 Barrow Atqasuk ITEX Thaw v1.txt> contains data representing the thaw depths of ITEX plots in Barrow and Atqasuk in a text tab delimited format. The data presented are daily to seasonal thaw depths of 48 plots (24 experiment open-top chamber plots and 24 control plots) at four sites (Atqasuk Wet Meadow, Atqasuk Dry Heath, Barrow Wet Meadow, and Barrow Dry Heath).

For control plots 2-4 of the corners were measured and the average is presented. For experimental open-top chamber plots only the center of the plot was measured and thus presented. META-DATA FORMAT The following prefixes have been used to designate data type. str - indicates string (text) data ysn - indicates yes or no data dtm - indicates date time data num - indicates numeric data All string data within a column contain the same number of characters. The meaning of each character is defined at each position by stating the length of the identifier with a numeric and placing all the data codes used within parentheses directly after the numeric. For example: strYear - year of recording 4(1998-2001) The above example describes a column that represents the year the data was recorded, it is string data that is always four characters in length and the only data codes used are 1998, 1999, 2000 and 2001.
