NPEO PMEL/CRREL Ice Temperature and Mass Balance Buoys for 2006 and 2007
The two Ice Mass Buoys reported here are the CRREL portion of the North
Pole Environmental Observatory, and are parts of a campaign to monitor the ice
and snow cover of the entire Arctic Ocean, detailed at
http://www.crrel.usace.army.mil/sid/IMB/index.htm
The IMB buoys themselves are described at
http://www.crrel.usace.army.mil/sid/IMB/buoyinst.htm
Each was deployed by PMEL at the NPEO deployment camp in April of their
deployment year. NP2006B_9115 lasted until late January 2007; NP2007D_9114
survived until early January 2006, in both cases drifting toward Fram Strait
east of Greenland. These buoys are complimented by PMEL Weather and Radiometer
buoys.
Because of the large temperature arrays presented by the IMB buoys and
differing time stamps, their data is provided in three separate files. All
contain header information ended by a line with a single character '#',
followed by the data in tab-delimited ASCII columns. The left-most columns
provide a time stamp for that data line.
- IceTemp files: Internal Ice Temperature (degrees C) from the air through the
ice into the ocean beneath typically every 10 cm and every 2 hours. The header
lists the heights/depths at which temperature was measured. A depth of 0 is the
position of the top of the ice at the time of deployment, positive numbers are
heights above the surface of the ice, negative numbers are depths from the top
surface of the ice. To the right of the time stamp the remaining columns list
thermistor-measured temperature at those depths. Missing data are flagged
as -99.0.
- MetMass files: Ice thickness and snow depth measured with acoustic pingers,
and atmospheric pressure and air temperature typically recorded every two hours.
Missing data is flagged as -99.0. A detailed discussion of ice mass balance
may be found on the CRREL Buoy Website.
-- Position files: GPS position of the buoy.
