FRAMZY 2008 - Fourth Field Experiment on Fram Strait Cyclones and their Impact on Sea Ice: meteorological measurements of 7 autonomous ice buoys


The FRAMZY 2008 experiment aimed at the measurement of the sea ice drift in the Fram Strait and its relation to the atmospheric forcing, primarily to that by cyclones. FRAMZY 2008 was the fourth experiment with this objective and followed the FRAMZY experiments in 1999, 2002 and 2007. On 20 January 2008, seven CALIB (Compact Air-Launch Ice Buoys) buoys were deployed from a transport aircraft in a regular array of 200 km by 100 km size centered at 82.6¿N, 1.0¿E in the northern part of Fram Strait. Buoys measured autonomously air pressure, temperature and position at approximately one-hourly intervals and transmitted the data via the Argos satellite system.

                The lifetime of the buoys before they were lost at the ice edge or due to the breaking of ice was between 7 and 39 days (final date 28 February 2008). The southernmost position reached by a buoy after 39 days was 76.2¿N, -12.0¿E, corresponding to an average drift speed of 16.9 km per day or 0.20 ms-1. During the FRAMZY 2008 period eight cyclones passed through Fram Strait. The paper presents details of the ice motion and the atmospheric conditions. In the appendix 12-hourly maps of sea-level pressure and surface air temperature as analysed by the ECMWF, daily maps of ice concentration and daily NOAA satellite images are presented.
