But this link works: https://stvno.github.io/page/cliwoc/ maybe the projected moved??

- `id`'s in `dck`'s 194, 201, 202, 203 and 227 are all derived from the same 5-digit ship identifiers. Leading digits are removed where needed.

- Some ship `id`'s are callsigns and need to be reformat to enable linking of data from the same ship across `dck`'s and to be linked to metadata information in WMO Publication No. 47. For more information see [Kent. *et al.,* (2007)](https://doi.org/10.1175/JTECH1949.1) and [Freeman. *et al.,* (2017)](https://doi.org/10.1002/joc.4775).

- Some ship `id`'s are callsigns and can be used to link to metadata information in WMO Publication No. 47. However some callsigns have been modified in some `dck`, or corrupted, so processing attempts to recover the original callsign in these cases. For more information see [Kent. *et al.,* (2007)](https://doi.org/10.1175/JTECH1949.1) and [Freeman. *et al.,* (2017)](https://doi.org/10.1002/joc.4775).

- Where an `id` is identified as a callsign or an identifier listed in WMO Publication No. 47, other `id`'s containing the same character string are flagged and leading digits are removed. This is with the purpose of homogenising the callsigns across `dck`'s. |
