Hello everyone - [Previous version April 2021] - Updates findings from a 30 plus year study of log books, journals and other sources documenting traditional British and American sperm whaling in the 1800s to the north of Australia including Indonesian and New Guinea waters. Charts over 1450 sperm whale sightings. The data comprises 970 British sightings extracted from the logs of 14 British whaling voyages covering the period 1820 to 1850 and 481 American sightings from a slightly later period. What’s New in this version? Key differences are the addition of another 74 British sightings, and an ability to track American voyages and compare them to the British voyage tracks. Introduction of View Map functionality on the Whaling History website facilitates this. Voyage tracks allow us to determine ‘where whaleships went over time and where the sighted whales’ confirming patterns of deployment. The main outcome of this is the finding that American vessels overwhelmingly approached Indonesia from the south-west. This was previously not obvious. Voyage tracks also show that the majority of early American voyages were forays to the south of Sumatra, Sumba and to the west of Timor rather than being voyages into the Indonesian Archipelago. American voyages through Archipelago did not become commonplace until the mid-1840s. In previous versions of the Paper I also wondered whether whaling vessels identified as sailing north-west from New Zealand (presumably the American Whaling Fleet?) or north from Australia (the Colonial Whaling Fleet?) undertook whaling around New Guinea and the Solomons. The evidence in American voyage tracks reveal that some American whaling vessels did sail east across the south of Australia and then north between the east coast of Australia and New Zealand from the 1840s. These vessels did undertake some whaling to the east of the Solomon Islands before continuing their voyages into the Northern Pacific. Finally, the original study findings continue to be reaffirmed. This is, that the British and American fleets whaling to the north-west of Australia, in Indonesian and in New Guinea waters deployed differently. Essentially, the Americans transited Indonesian waters whereas British vessels remained within the Indonesian Archipelago, moving from whaling ground to whaling ground. Remaining within the Archipelago meant that the British needed to reprovision locally. The key reprovisioning ports were Kupang on Timor, Kema on North Sulawesi and to a lesser extent Ternate in the Molucca [Maluku Islands]. https://www.academia.edu/71899655/British_Sperm_Whaling_Activity_to_the_Nort...
