All the drifter data is broken into three smaller files for easier downloading and updating.


The file "buoydata_1_5000.dat-gz" contains data from the earliest 5000 drifters. This file was revised and completed on November 2013, you need to update it if your version is prior to this date.


The file "buoydata_5001_10000.dat-gz" contains drifters 5001 through 10000. This file was revised and completed on November 2013, you need to update it if your version is prior to this date.


The file "buoydata_10001_MMMYY.dat-gz" contains the updated data, through month MMM of year YY.


These data files are accompanied by metadata directory files containing deployment time and position, drogue off date, last time and position, death code, etc. for each drifter. The directory file for the drifters in "buoydata_1_5000.dat-gz" is called "dirfl_1_5000.dat". The directory file for "buoydata_5001_10000.dat-gz" is called "dirfl_5001_10000.dat".


The directory file for "buoydata_10001_MMMYY.dat-gz" is called "dirfl_10001_MMMYY.dat". This file is updated each time the data base is updated.


The final versions of files: buoydata_1_5000.dat-gz, buoydata_5001_10000.dat-gz, dirfl_1_5000.dat, and dirfl_5001_10000.dat, were created on November 2013 with the most up to date information, including the final drogue status reanalysis.
