Arctic Ice Dynamics Experiment (AIDJEX) (1975-1976)
Entry ID: gov.noaa.ncdc.C00307

[ Update this Record ]

Summary

Abstract: During the Summer of 1975 the Arctic Ice Dynamics Joint Experiment (AIDJEX) maintained four manned camps on ice floes in the Arctic Ocean. Instrumentation located at those camps, or deployed on floating data buoys, recorded surface and geostrophic winds, ocean current velocity at 2 and 30 meter depths, and camp (ice floe) position. Data are archived as daily average values for each camp, as well as ice velocity and smoothed positions. Surface pressure and geostrophic wind data are also available at 6-hourly intervals. From April 7th through 10th, 1976 the submarine USS Gurnard participated in the AIDJEX by tranversing 777 nautical miles along three track lines in the Beaufort Sea, collecting ice thickness data from upward-looking acoustical soundings (sonar). The resulting digital data set is a profile of the sea ice layer, including latitude/longitude, 'ping' interval, surface beam diameter, number of data points, and ice thickness. The termination of the AIDJEX project also signals the end of the AIDJEX databank. All validated source data have been submitted to national data banks for permanent retention, together with pertinent documentation. Copies will be distributed from those facilities upon the request of interested scientists. The data acquired during the AIDJEX main experiment have been validated, for the most part, by the principal investigators and analysts. Copies of finished data sets had been supplied to the data bank in several forms, such as unformatted binary using Fortran or Extended Fortran and in formatted SCOPE Internal Display code. Each set is in the format preferred by the analysts' that created it. The units of common variables also vary with the analysts' preference--for example, time in minutes of the day, dates as year-days of AIDJEX days (starting 1 January 1975), latitude and longitude in decimal degrees, and position in rectangular coordinates originating at the North Pole. Data presented to national data banks whose computer centers are not compatible with the CDC 6400 have been prepared in fixed block record size, external BCD,or even parity. Documentation is included as part of the headers and data records. Narrative descriptions of the data may be included as part of the header.

Purpose: To make a wide range of climatic data available to researchers and the public.
