In 1845, Sir John Franklin, a seasoned officer of the British Navy, embarked on a bold expedition to chart a navigable route through the Arctic archipelago, connecting the Atlantic and Pacific oceans. The voyage commenced with HMS Erebus and HMS Terror, each equipped with the most advanced technology of the time. The ships were reinforced with metal to withstand the icy clutches of the Arctic and additionally equipped with steam engines to augment their thrust.
The Franklin expedition was composed of 129 individuals, including experienced officers like Captain Francis Crozier, a veteran of several polar journeys, and Commander James Fitzjames, an officer of considerable promise. The expedition was provisioned with advanced preserved food and other necessities, ensuring they had enough supplies to sustain them for a duration of three years. This pioneering technique for food preservation involved enclosing an assortment of provisions, including animal proteins, broths, and plant-based fare, in hermetically sealed metal containers, thereby providing a reliable source of nourishment throughout the voyage and enabling more far-reaching expeditions than those undertaken by previous explorers.
Practical Tips
- Consider forming a small team to tackle a challenging project, mirroring the dual-ship strategy. Each member could take on a specific role, such as research, execution, or logistics, to efficiently reach a common goal, like organizing a community clean-up or starting a local book club.
- Consider building a small-scale model of a reinforced ship using everyday materials to understand structural integrity. Use cardboard, plastic bottles, and aluminum foil to mimic the metal reinforcement and design a propulsion system using rubber bands or small motors. This project can deepen your appreciation for engineering solutions to environmental challenges.
- You can extend the shelf life of your groceries by experimenting with different preservation techniques such as canning, dehydrating, or vacuum sealing. By learning these methods, you can reduce food waste and save money. For example, you might dehydrate seasonal fruits to enjoy them year-round or can your homemade sauces for extended storage.
- Create a "survival pantry" challenge to test the effectiveness of hermetically sealed foods in your diet. Over a set period, such as a month, incorporate commercially available hermetically sealed foods into your meals, noting any changes in taste, quality, and your overall satisfaction. This will give you practical insight into the benefits of hermetically sealed foods for long-term sustenance.
The book emphasizes the pivotal role of Franklin's expedition in Britain's endeavor to chart the unknown regions of the Arctic. For centuries, European explorers were captivated by the prospect of a more direct route to the wealth of the East, which they believed could be achieved by sailing through the hard-to-find Northwest Passage. Britain, a nation determined to uphold its dominance over the seas, sought fervently to discover a maritime route through the Northwest Passage, thereby reinforcing its position as a preeminent power on the world stage.
By 1845, a few remaining unexplored areas were all that was left for explorers like Parry, Ross, and Franklin to complete the mapping of the Arctic archipelago. Franklin's objective was to successfully navigate the Northwest Passage for the first time, an endeavor that would elevate the British Empire's prestige. The expedition aimed at more than just exploring new territories. The authors point out that it also carried a significant scientific burden. The mission's objective was to collect data on magnetism, earth sciences, and various components to enhance our knowledge of the distant northern territories.

In 1848, after Franklin and his crew disappeared, British naval authorities promptly organized three separate expeditions to locate the missing explorers. The expeditions' foremost objective was to find and provide assistance to any survivors from Franklin's team, and when possible, to retrieve artifacts from their journey.
At first, the Admiralty believed that Franklin's expedition had encountered only temporary difficulties, perhaps because the ships had become trapped in the ice. The common assumption held that their plentiful supplies would provide for their needs over a significant period of time. Consequently, the initial rescue efforts were concentrated on locating the ship and its crew to provide assistance and secure their safe return to their native country. Despite various initial efforts to discover it, the exact whereabouts of the expedition remained elusive, heightening concerns. Later expeditions, which shifted focus from their original objectives, dedicated...
In 1981, Owen Beattie, who specialized in forensic anthropology at the University of Alberta, set out to investigate the sites associated with the Franklin expedition, with the goal of applying modern forensic techniques to unravel the enigmas of its demise. Owen Beattie and his research team embarked on an expedition that traced the route of the doomed explorers to King William Island. The discovery of bones near a circular tent formation provided Beattie's team with the first tangible evidence regarding the physical condition of the people who perished at that location.
Analysis of the skeletal remains showed clear indications of metabolic disruption, confirming for the first time that the sailors' last, desperate voyage was severely affected by a critical lack of vitamin C, resulting in scurvy. The examination of skeletal remains indicated alarmingly elevated levels of lead, significantly...

The investigation by Beattie and Geiger, involving the analysis of the crew's remarkably preserved soft tissues and hair as well as assessing the lead levels in the canned supplies of the expedition, concluded that lead poisoning played a significant role in the demise of the Franklin expedition's crew. Beattie's investigation suggested that the crew's declining health worsened due to lead contamination from poorly sealed cans, which further impaired their already weakened state, decreasing their chances of enduring the harsh Arctic conditions.
Beattie and Geiger underscore the significance of detecting high levels of lead in the hair samples. Hair growth assimilates various trace elements from the bloodstream, providing a sequential record of exposure. Analysis of the sailors' hair revealed increased levels of lead, indicating that the contamination occurred during their voyage instead of stemming from earlier environmental exposure back in England. The expedition's anticipated success was undermined by the very...
