ABPR data consists of time, ocean bottom pressure, and temperature.  This 
archive contains the records for Arctic Bottom Pressure Recorders #1 and #3 
installed near the North Pole in April 2005 in about 4300 meters of water.  
The format of the tab-delimited ASCII data is specified in the header 
of each file. 
 
Files:
ABPR_1.txt    89deg 15.26min North   060deg 21.58min East 
              2005-4-24/0400 UTC to 2007-4-26/2345 UTC,
              two years duration.
 
ABPR_3.txt    89deg 14.85min North   148deg 07.54min East 
              2005-4-24/2045 UTC to 2006-10-6/2345 UTC,
              about 1.5 years duration.
 
These data have been edited for obvious bad points and ABPR_3.txt has been 
edited for a rapid pressure jump of about 8.5 cm that we think was due to 
settling of the pressure gauge into the bottom. Other than that, these are 
essentially the original data as recovered by acoustic modem in April 2006 
and April 2007. 
 
Although not formally part of the North Pole Environmental Observatory, this 
project gets logistical support from NPEO.  Details may be found at
