Abstract:
3 drifting buoys were deployed on ice floes on the Weddell Sea (68 degrees S,
55 degrees W) in November-December 2004, as a part of the international
expedition Ice Station Polarstern (ISPOL,
http://www.ispol.de/). These ice
beacons were manufactured by Metocean, and measured GPS location, air pressure
and air temperature. The data were transmitted using the Argos system.
One of the buoys,
... identified with Argos ID number 52292, was recovered in late
December 2004. Two buoys, with Argos IDs 1154 and 5892, are still operating at
the time of writing of this (November 2005). They also trasmit their data to
the Global Telecommunication System (GTS), with IDs 71643 and 71645. One of the
buoys drifted around the Antarctic Peninsula, the other headed northeastward
past the island of South Georgia.
The buoy data have been processed and quality checked at the Finnish Institute
of Marine Research (FIMR). The processed data set includes GPS location, air
pressure and temperature at 1-hour resolution. The Argos location information
is also available, as an unprocessed raw data.
