This data set contains the Acrobat files collected along transects conducted near Barrow, AK from August 20 - 29, 2013. Details of the latitude, longitude, date, and time are listed in the event log that is archived at this site. Date /time (Universal Coordinated Time (UTC) day, decimal time), time, position, bottom depth, and measured variables are listed as separate columns in each file. Each Acrobat file is named according to the transect line sampled, the year, and the year day of data collection (e.g., line_2_2013_232.dat). The Acrobat data acquisition system failed prior to a second occupation of Line 2 and thus could not be used.
