- For the period 1663 to 1860, [CLIWOC logbook](https://www.historicalclimatology.com/cliwoc.html) `id`'s from `dck` 730 are converted to ship names using information from the project: <br> https://projects.knmi.nl/cliwoc/download/shiplogbookid21.htm This link does not work.

- For the period 1663 to 1860, CLIWOC logbook `id`'s from `dck` 730 are converted to ship names using table information from a MS ACCESS database that is no longer available online. Some information is available from: <br> https://www.historicalclimatology.com/cliwoc.html

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

- For the period 1663 to 1863 ship names from the **US Maury collection** `dck` 701 are extended using information from [this link](http://icoads.noaa.gov/software/transpec/maury/mauri_out). Also data with a missing `id` from `dck` 701 is split into voyages by manual inspection.

- 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. |
