Identifying historical ship logs

A catalogue of logs, journals, shipboard diaries, letters, and all

forms of voyage narratives,

1788 to 1988,

for Australia and New Zealand, and surrounding oceans.

Identifying historical ship logs

ABERCOMBY,1838Trading schooner, 143t, J.Butcher: Swan R, 12.2 – Mauritius. Journal by Thomas Mellersh, AJCP M reel 466

“Log of Logs” provides a brief description of the voyage of each vessel (timing, origin / destination) and the type of log recorded.

The different types of logs include:•Captain’s and Masters Log•Exploration Log•Surgeon’s Log•Passenger Journal

Constructing an inventory of ship logs for the Australian / Pacific region

• Identified all ships entering the Australian / Pacific region with AJCP references.

• A number of ships entered the Australian / Pacific region for a short period of time only (e.g. on trading routes or exploration further afield). These logs were noted, however particular focus was given to those ships that remained within the Australian / Pacific region for an extended period of time.

• All AJCP references were entered into a spreadsheet document, recording details including ship name, voyage dates, origin and destination(s).

Compiled database

Identifying a shortlist of logs for examination

• The identified AJCP references were then cross-checked with other archives of International Scientific expeditions

e.g. Clive Wilkinson (UEA): “19C Logbook and Ship Movement Directory”

– This provided additional information (e.g. the likelihood of instrumental data for the different shipping logs)

– A list of ‘more favourable’ ship logs were identified from the identified 336 AJCP Log of Log references
