Platform Transmitting Terminal (PTT) tracking of Antarctic Fur Seals at Bird Island, South Georgia, from 1995 - 2010

Platform Transmitting Terminal (PTT) tags were used to track Antarctic Fur Seals (Arctocephalus gazella) from Bird Island, South Georgia, 1995-2010. PTT tags use the ARGOS satellite system to collect geospatial data. Tags were deployed on breeding females during the summer, to provide information on where the seals are foraging during lactation and into the winter months.

Statement: The PTT data files include quality information, under the fields loc_class and loc_ind. The loc_class field indicates an error value for the location which is determined by the number of satellites the tag connected with. Codes are detailed in readme.txt file. The loc_ind field indicates the IQ (Quality indicator). This indicator gives information on the transmitter in terms of X and Y. X (the first digit in the loc_ind field) indicates residual error on the frequency calculation. Y (the second digit in the loc_ind field) indicates transmitter oscillator frequency drift between two satellite passes. Meanings of the values of X and Y are detailed in the readme.txt file.
