Time-depth recorders attached to chick-rearing murres in 2004

Raw text files generated by Lotek download software. After a preamble including the logger serial number (8XXX), the data file presents three columns: the time & date, the temperature in degrees Celsius and the pressure in psi. To convert psi into approximate depth, multiply by 0.705. The text files are organized into three folders representing the three deployments. Each file name also has the last five digits of the band number of the individual bird to whom the TDR was attached (the total band number is 996XXXXX, where XXXXX is the unique identifier of the bird and included in the title of the file). The band number serves as the identifier to relate it to the meta-data file that includes sex, age and other attributes of the bird.
