Dr Sam Willis speaks with Charlotte Ward to explore the remarkable history of Lloyd's Register, perhaps the most influential book for the maritime world ever to be published. It all begins in a coffee house run by Edward Lloyd, and a book, called the Register of Ships, first published in 1764, to give underwriters and merchants an idea of the condition of the vessels they insured and chartered. Maritime history from that moment on was fundamentally changed, particularly in relation to safety at sea. The Lloyd's Register Foundation now curates an immense archive of material relating to global maritime history.
But we begin this episode as ever by catching up on our sailors on the whaleship swan of Hull, trapped in the ice off the west coast of Greenland in the new year of 1837. Each week we have been reading a little from their logbook – which is now kept in the archives of the national maritime Museum in London. They have been trapped now for almost four months. Life has been terrifying and they are entering a period of intense cold. Even the most minor of events is a major occurrence for these men perched on the cliff edge of their existence.

One of the key aspects of maritime historical research that is helping us understand our modern world is the use of ships logbooks to understand and map climate change in various regions across the world. Today Dr Sam Willis Dr Matthew Ayre, a Climate Detective (or more officially a Historical Climatologist) at the Arctic Institute of North America. Matt uses 200 year old documents surviving from the Arctic whaling trade to look back at the Arctic climate.It's an important topic. Over the past 30 years, the Arctic has warmed at roughly twice the rate as the entire globe, a phenomenon known as Arctic amplification.
Ships’ logbooks are now an accepted data source in climate change studies.Matt is an expert on the particular issues surrounding logbooks from the Arctic region in what is known as the pre-instrumental period and has tackled important questions linked to this research – how, for example, can you reliably express narrative descriptions of wind, weather and sea ice in index form? An dhow then can you most effectively manage scientific analysis fo such data, which – remember -- was not recorded for such purposes. How do you digitize historical logbooks?
