Time-depth recorders attached to chick-rearing murres in 2007

Raw text files generated by Lotek download software. After a preamble including the logger serial number, 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 different deployments. Each file name has the last five digits of the band number (the band number started with 996, which was dropped for simplification in the field) of the individual bird to whom the TDR was attached. 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. In some cases, additional information (e.g. site location) were included in the file name to simplify work in the field, but that is not needed to uniquely identify the bird.
