POLAR 5 airborne campaigns PAMARCMiP and TIFAX in 2012

 

   

During the flights of PAMARCMIP and TIFAX, ice thickness was measured with a sensor, called EM-bird, towed by the research aircraft Polar 5 (Fig. 1). This instrument is pulled under the hull of the aircraft by means of a winch for takeoff and landing. For the surveys, the probe is towed on an 80 m long rope twenty meters above the ice surface.

The PAMARCMiP project is organized around the capacity of the Polar 5 aircraft to provide unique data of aerosol, meteorological conditions, as well as sea ice thickness in the high Arctic. The strategy is to obtain snapshots of critical parameters in order to close gaps in our understanding of Arctic conditions and processes.

 

The PAMARCMiP 2012 campaign started from Longyearbyen, Svalbard, eastbound to Resolute Bay, Nunavut. The PAMARCMiP campaign has been performed from 17th of March to 9th of April 2012, whereby 15 research flights were done. The research flights commence out of Longyearbyen (Svalbard), Station Nord (Greenland), Alert (Nunavut), Eureka (Nunavut) and Resolute Bay (Nunavut). One of the highlights was the coincidence flights with a Danish Twin Otter from Alert to validate the CryoSat 2 sea ice retrievals. Similar sea ice conditions as in April 2009 and April 2011 were found, characterized by reduced occurrence of multiyear ice.

The TIFAX campaign took place in summer 2012, following TIFAX campaigns in 2010 and 2011. In total 3 flights were performed between 19th and 21st of July 2012 north of Greenland and across the Fram Strait. The ice thickness measurements confirm findings made on the basis of satellite imagery: The summer of 2012 was characterized by increased advection of thick multi year ice out of the Fram Strait. However, the first year ice was relatively thin compared to earlier summers (Fig. 2).
