Version history:
\n2019-11-25: version 5: changed incorrect LONGITUDE value of sample 11256 (from\u00a0180.033.0087 to 180.0000).
\n
2019-07-29: version 4: removed all \"placeholder\" columns containing no data (-999 only). These columns were included in the original files from ODF to indicate the expected datasets.
