Australian National Maritime Museum 2013 © 3 GLOSSARY Antarctic bottom water The coldest and densest water mass in the ocean. Formed in particular places in Antarctica when surface water cools and becomes more dense and so sinks to the ocean floor. Anthropologist Anthropologists examine, analyse, report on and compare different communities and how they grow, develop and interact. Avalanche A fall or slide of a large mass of snow and ice which has detached from where it rested. Biologist Biologists study humans, plants, animals and the environments in which they live. Calve When the ice flowing from a glacier reaches a body of water it begins to float and may break off the glacier becoming an iceberg. Desert An area where precipitation is low and evaporation is high creating very little moisture in the air. Antarctica is a “white desert”. Ecosystem A system formed by the interactions of the living organisms (plants, animals and humans) and physical elements of the environment. Environment The total physical and biotic features and influences surrounding a place or organism. Geographical issues Areas of concern that arise due to changes in environments and which can be in spatial and ecological dimensions. Geologist Geologists study the solid and liquid matter that constitutes the Earth as well as the processes and history that has shaped it. Glaciers Glaciers are snow, compressed over many years, which thicken into ice masses. They are like rivers of ice and move slowly. Freshwater. Habitat The environment in which an organism lives: the land and resources (food and shelter) required to support an organism. Hypothesis A predictive statement which can be tested using a range of methods: most often associated with experimental procedure. Ice floe A large, flat, sheet of sea ice that has broken off contact with the coast where it was formed and is floating in open water. Sea-water.

Australian National Maritime Museum 2013 © 5 PRIMARY STAGE 3 A. Timeline S3 S4 Construct a timeline of exploration in the Antarctic region and other world events of the time of Shackleton’s expedition. The timeline needs to be to scale and record at least ten of the events listed below. Label each event with a date and title. 1773 British explorer James Cook crosses the Antarctic Circle in January and circumnavigates Antarctica. He does not sight land, but finds evidence that a southern continent exists. 1788 The First Fleet arrives in Australia. 1891 - 1821 Thaddeus Bellingshausen, a Russian naval officer, circumnavigates Antarctica and is the first person to cross the Antarctic Circle since Captain Cook. 1823 British whaler James Weddell discovers the sea later named after him and reaches the most southerly point to date. No one else penetrates the Weddell Sea again for 80 years. 1840 British naval officer and scientist James Clark Ross takes two ships, the Erebus and the Terror, to within 80 miles of the Antarctic coast. He is stopped by a massive ice barrier, known as the Ross Ice Shelf. He also discovers an active volcano that he names after his ship Erebus. 1885 Karl Benz builds the first motorcar. 1899 Carsten Borchgrevink leads a British expedition to Cape Adare and builds huts. This was the first time that anyone had spent a winter on land in Antarctica. 1901 Australia becomes an independent nation with Federation. Australian National Maritime Museum 2013 © 6 1902 Robert Falcon Scott leads his first Antarctic expedition to the South Pole, with Ernest Shackleton and Edward Wilson. They are forced to turn back two months later having reached 82˚ south, suffering from snow blindness and scurvy. 1903 The Wright brothers make the first powered airplane flight. 1907 - 1909 1912 - December 1912 – January Ernest Shackleton leads an expedition to within 156 km of the South Pole, but turns back after supplies are exhausted. Norwegian Roald Amundsen is the first to reach the South Pole. Robert Falcon Scott reaches the South Pole three weeks after Amundsen. 1914 World War One begins. 1915 Ernest Shackleton returns to Antarctica in October in an attempt to complete the first crossing of the continent. The attempt is unsuccessful. 1916 Ernest Shackleton and five men depart Elephant Island on an 800 nautical mile voyage across the Southern ocean to reach South Georgia. According to Sir Edmund Hillary, “this attempt to rescue all of Shackleton’s 28 men stranded in Antarctica is the greatest survival story of all time”. 1956 A United States of America aircraft lands at the South Pole, the first people since Scott in 1912. 1958 The first successful land crossing via the South Pole is led by British geologist Vivian Fuchs with New Zealander Edmund Hillary leading the backup party. 1961 Antarctic Treaty comes into effect. Australian National Maritime Museum 2013 © 7 B. History of Shackleton's Epic Supplied by Shackleton Epic http://shackletonepic.com/ "We bailed with the energy of men fighting for life." (From South: Sir Ernest Shackleton) With Englishman Robert Scott and Norwegian Roald Amundsen having reached the South Pole in 1912, Sir Ernest Shackleton, not to be outdone, embarked on the most ambitious polar expedition of all time – the Imperial Trans-Antarctic Expedition – a bid to cross Antarctica from the Weddell Sea coast to the Ross Sea coast. Shackleton’s Imperial Trans-Antarctic Expedition planned to utilise two ships to accomplish its mission: the Endurance would carry Shackleton and his main party across the Weddell Sea to a landing site near Vahsel Bay from which Shackleton would begin his cross-continent journey, while a second ship, the Aurora, under the command of Aeneas Mackintosh would embark from Hobart, Australia to a landing at McMurdo Sound in order to enable a second crew to lay a series of inland supply depots for the final portion of Shackleton’s march across the continent via the South Pole. On the Weddell Sea side, however, things did not go as planned, with the Endurance becoming trapped and finally crushed by pack, leaving Shackleton and his crew with little hope of survival. Rather than succumbing to the inevitable, they eked out an existence on the pack ice, drifting north for another five months from November 1915 to April 1916 until the melting ice finally released them into the Southern Ocean. It was 1916, the First World War raged on, and the crew of the Endurance numbered 28 men in three small wooden lifeboats adrift in the roughest ocean in the world under the command of the ever-sanguine Shackleton. The men paddled and sailed for several harrowing days to reach Elephant Island – a bleak and remote island home only to colonies of Elephant seals and penguins. With the long dark winter looming, and his men half-starved and desperate, Shackleton realised he would have to go for help or all would die. What followed was what Sir Edmund Hillary described as the greatest survival story ever undertaken: Shackleton and five men left Elephant Island in late April 1916 on an 800-mile voyage across the notoriously treacherous Southern Ocean in the lifeboat James Caird. For 17 days they battled constant gales, terrible cold, and mountainous seas in a leaking 22.5 ft wooden boat, not only finding but managing to land on the small, remote island of South Georgia. Shackleton and two of the crew of six from the James Caird, Worsley and Crean, then climbed over the precipitous, heavily glaciated mountains of South Georgia to reach the refuge of the whaling station at Stromness on the other side – a journey that the world’s top mountaineers in the modern era have been unable to replicate in the time Shackleton took. Ultimately Shackleton was able to save the remaining crew of the James Caird on the other side of South Georgia and rescue all 22 of the crew members who had been left stranded on Elephant Island – an epic triumph of endurance and leadership. Launching the James Caird, 1916. Photograph by Frank Hurley Australian National Maritime Museum 2013 © 8 The 21st Century Expedition Supplied by Shackleton Epic http://shackletonepic.com/ "…then, just when things looked their worst, they changed for the best. I have marvelled often at the thin line that divides success from failure and the sudden turn that leads from apparently certain disaster to comparative safety." (From South: Sir Ernest Shackleton) Shackleton Epic has been in development since 2008, when Alexandra Shackleton, granddaughter of Sir Ernest, approached renowned British/Australian adventurer Tim Jarvis AM FRGS, with the idea of an expedition to honour one of the greatest leadership and survival stories of all time. Now, a crew of five British and Australian adventurers have joined expedition leader Tim Jarvis, AM FRGS, in an attempt to become the first to authentically re-enact Sir Ernest Shackleton’s treacherous boat voyage from Elephant Island to South Georgia, followed by the difficult crossing of its mountainous interior. To this day, no-one has successfully recreated Shackleton’s complete ‘double’ journey across sea and land using traditional gear. British/ Australian adventurer Jarvis, 46, a veteran of multiple polar expeditions, believes it is the most challenging expedition of his life. The only concessions to the use of period equipment are the storage of modern emergency equipment and radios on board Alexandra Shackleton, and the presence of a support vessel. The British and Australian team members include Skipper Nick Bubb, Mountain Leader WO2 Barry Gray RM, Sailor and Navigator Paul Larsen, Expedition Bosun Petty Officer Seb Coulthard RN FRGS, Expedition Cameraman Ed Wardle; and Reserve Sailor Paul Swain. On January 23 Jarvis and his crew set out to emulate Shackleton’s voyage across 800 nautical miles of the most challenging and treacherous seas on the planet – the Southern Ocean – sailing from Elephant Island to South Georgia aboard Alexandra Shackleton, an exact replica of Shackleton’s 22.5’ (6.9m) whaler, James Caird. Jarvis and his crew are presently at South Georgia and he and two of his crew will traverse its mountainous interior shortly, to reach the former whaling station at Stromness. The expedition will culminate in a pilgrimage to Shackleton’s grave at Grytviken. Jo Stewart. Shackleton Epic Australian National Maritime Museum 2013 © 9 C.

Shackleton Epic Questions - Glaciology and Rising Temperatures. 1. What percentage of the world’s snow and ice are found in Antarctica? 2. What is happening to the world’s biggest ice sheet? 3. If air temperature has increased by half a degree Celsius for each decade over the past 50 years, what is the overall increase in temperature in that time? 4. What is one effect of this increase in temperature? 5. What is the major concern about the ice shelves collapsing? 6. Why is water warming in the Southern Ocean? 7. How can scientists measure the depth of the ice mass? 8. How is ice melting from below the ice mass? 9. Explain how sea levels may rise. 10. How many metres do scientists predict that sea levels may increase this century? Australian National Maritime Museum 2013 © 13 Something to Think About - Rising Sea Levels Half of the world’s population live in low-lying places close to the coast. A rise in sea level would have a huge impact on many communities. Here are some scenarios of what would happen if the sea levels rise by one metre. Tuvalu is a tiny country made up of a group of islands in the South Pacific. It would be almost completely underwater with a one metre rise of the ocean. Its entire population of 11,000 people would have to be evacuated and relocated. London, the capital city of England, would completely change as the Thames River would flood putting important landmarks such as the Houses of Parliament at risk. China is the world’s most populated country. If the sea level rises by one metre one third of Shanghai would be underwater. Throughout the country more than 70 million people would be affected.

The Food Web Food webs are representations of the predator-prey relationship between species within an ecosystem. Organisms are connected by the fact that each member of the group feeds on the one below it. Watch: www.youtube.com/watch?v=LR9L_k_GJEo View this four minute David Attenborough clip from BBC Worldwide. It provides a good introduction to krill and the humpback whale, which is relevant for constructing a food web. Create an Antarctic Food Web Start to understand the ecosystem in Antarctica by creating a visual food web on the classroom wall. Follow the instructions below. Step 1: On the classroom wall mark out a large triangle, with the base at the bottom. Divide this into four layers to represent different levels of the Antarctic food web. Step 2: Discuss and define what a food web is. Label each level as: Tertiary Consumers (Predators) Secondary Consumers Primary Consumers Primary Producers Step 3: Have students create small drawings, paintings or craft items to represent life from the Antarctic seabed. eg: small crustaceans, worms, shellfish, molluscs, sea urchin, starfish, sea cucumbers, small corals and sponges. Step 4: Paint the lowest level at the base with sponge technique and finger painting to demonstrate the mass of micro-organism life forms. Explain phytoplankton and zooplankton. Australian National Maritime Museum 2013 © 20 Step 5: Along the very bottom of the base paste the art and craft representing the seabed. Step 6: Scatter the drawings of animals from the activity in C1 on the floor of the classroom. Select various pictures, identify the animal and get the students to name it and give some basic information about it. Discuss what it might eat and where it belongs in the food web. Start categorising different groups and then pin the pictures into each relevant section of the food web, ensuring that the top level has the least pictures to demonstrate that at the top there are very few. Do animals adapt to their environment? Experiment: The “Blubber Glove” experiment demonstrates how animals such as seals and penguins have adapted to Teacher information only The class should produce a web that reflects the following: Tertiary Consumers (Predators): Orca (Killer) whales Secondary Consumers: whales, seals, large fish, penguins Primary Consumers: krill, shrimp, small fish, squid Primary Producers: phytoplankton, zooplankton and seabed communities their environment, allowing them to keep warm in such a freezing environment.

Jo Stewart Shackleton Epic E. Clothing How do you dress to survive in the coldest, windiest place on earth? Polar explorers both in Shackleton’s time and now need to wear clothes that would protect them from ferocious winds and extreme cold temperatures that could drop to 50˚ Celsius below freezing. Layers work best as air is trapped between each layer and this air acts as insulation. Layers could be added or removed depending on the current weather conditions. Headwear and footwear was very important too. The clothing had to: Shackleton Epic Expedition. keep the body warm cover extremities such as ears and fingers allow sweat to disperse be light and comfortable to allow for movement British explorers to the South Pole used clothing made from woollen and cotton fabrics, favouring gabardine. They rarely wore fur except for their long wolf skin outer mittens. The Norwegians adopted Inuit clothing, wearing animal skins (seal, fox, wolf, reindeer, bear) from head to foot. Modern synthetic materials have revolutionised cold weather clothing. They are thermally efficient, breathable and windproof.

Shackleton Epic Australian National Maritime Museum 2013 © 27 F. Food additional information from Supplied by Shackleton Epic http://shackletonepic.com/ Food was very important to the men on expeditions to the Antarctic. Food was rationed to ensure that they would have enough for the duration of their stay. The Antarctic explorers did not have access to enough fruit and vegetables. These foods were often dried or powdered as they as they were not able to grow food in the Antarctic climate. The lack in nutrients from fresh fruit and vegetables often resulted in illnesses such as scurvy. It was important that the Antarctic explorers ate a good diet, to provide sufficient nutrition and energy. The cook had to be very resourceful and create new dishes with what was available. Local wildlife was often killed for food Pemmican This is an early form of a processed food first invented by the Hudson Bay Company and based on traditional Native North American Indian recipes. It was planned to be very compact, very nutritious and to remain edible for a long time. There are many recipes for Pemmican, but basically it consists of a mixture of pounded dried beef with beef fat (tallow) - other meats or mixtures of meats may be substituted for beef. Explorers of the heroic age of Antarctic exploration would take great care in where they bought their Pemmican from and the recipe that it was made to. Pemmican would provide nearly half of the total calories eaten out in "the field". Pemmican was a basic nutritious food that also had the added advantage of remaining edible for years though it is not terribly appetizing. It was often made up into a thick meat soup when simmered with melted snow/ice and Bovril known as "Hoosh"; this was eaten with sledging biscuits. Shackleton’s pemmican was devised in conjunction with Sir William Beveridge (Army food expert). Pemmican ingredients were: Beef protein preferred (Dried lean beef, Beef suet, Coarse Oatmeal, Sugar, Salt) Sledging Biscuits Along with Pemmican, sledging biscuits are part of polar lore. They are approximately 2" x 3" (7.5 cm 2) and fairly thick for biscuits. They are hard and rather like the boring crackers you get left in a mixed box of "biscuits for cheese" at Christmas. Along with pemmican, Huntley & Palmer’s sledging biscuits were one of the mainstays of food for Antarctic field parties. So much so in fact that sledging biscuits from Scott's 1912 polar expedition and Shackleton's voyage to South Georgia on the James Caird have even come up at auction in the last few years with price tags of $1,000 each. James Caird Eating Routine (three times a day) Cooking was done by two people sitting opposite each other, their backs against the side of the boat. The ‘Primus’ stove was placed on the floor and secured down using feet. Half a pound of sledging ration per man was then thrown into a 2 gallon ‘Nansen’ cooking pot. A third man would assist with securing the pot if the boat lurched suddenly. Daily meal consisted of: ‘Hoosh’, followed by one biscuit, 4 lumps of sugar, ¼ lbs of ‘Streimers’ nut food and a cigarette rolled from plug tobacco and tissue paper. Drinking water Aside from water used in cooking, each man received ±1 gill (1/4 pint) per man, per day and, one cup of hot milk served to each man every 4 hours (at watch change over or when anyone appeared to be extra cold). Towards the end of the voyage water was rationed even more to the point where hot milk was not served at watch change over. Their only water intake on day 1517, was from food alone.

Medical Issues in Antarctica For Shackleton and his men on the expedition, the conditions for exploration in Antarctica were very difficult. The weather was extreme. Their diet was very limited and rationed to ensure they would not run out of food. Living conditions were not comfortable. These three things impacted the health of members of Shackleton's crew and there were many medical issues and illness that were common and had to be avoided. Some of the problems experienced were frostbite, snow blindness, hypothermia, dehydration, scurvy and sunburn. Students require: Memory Game: Create cards to memorise six different illnesses or medical conditions experienced by Polar explorers. Use the cards to play a memory matching game. Use the table and follow the instructions below. 24 cardboard cards the same size Pictures collected from the Internet - at least one for each of the illnesses Scissors, glue, pen/pencil Table of information (see next two pages for template) Australian National Maritime Museum 2013 © 32 Name Symptoms Prevention FROSTBITE Partial freezing of exposed body parts such as fingers, ears, toes, and nose. Includes tingling, blister formation, and gangrene. Avoid tight fitting boots, being wet; change wet clothes ASAP. Wear beanies, mittens instead of gloves. Maintain good circulation. SNOW BLINDNESS A loss of vision and inflammation of the eyes. Caused by the bright glare Wear protective goggles off ice and snow. Serious with UV protective lenses. and painful, but usually temporary. HYPOTHERMIA An abnormally low body temperature resulting from extreme exposure to cold weather. Wear layers of waterproof and windproof clothing to create insulation. Avoid sweating too much; change wet clothes ASAP. DEHYDRATION Excessive loss of water from the body. If untreated can lead to shock. Carry good water supplies or a stove to melt snow when travelling. SCURVY (LACK OF VITAMIN C) Spongy and bleeding gums, bleeding under the skin, and extreme weakness. Eat lots of fresh food. In particular eat fruit and vegetables that are high in vitamin C. SUNBURN Picture Inflammation or blistering Wear sunscreen when outof the skin caused by side and reapply hourly. overexposure to direct Cover as much skin as sunlight. possible. Australian National Maritime Museum 2013 © 33 Aim of the game: To match and group four cards together for each medical issue. How to prepare: There are 24 cards, six of which are blank. There are four cards for each illness: Name, Symptoms, Prevention, Picture For each blank picture card do a internet image search and find a suitable picture for that illness. Print the image and paste onto the card. Cut out the cards. office.microsoft.com/en-us/ images How to play: Shuffle the cards and lay all of them face down. Select a card and turn it over to display the information Select another card and turn it over. If the information matches, select a third card. If the information does not match turn both cards back to be blank. Memorise where the cards are so that you can remember where matching cards lie Players may only keep cards when all four matching cards have been found What was life like? Imagine you are an explorer in Antarctica. You are ill and have been suffering from some of the complaints mentioned above. How are you feeling? What are you going to do? Diary: Write a diary entry, while wearing gloves or mittens, to experience empathy with the men from Shackleton's party. Imagine you are ill with one or two of the medical issues experienced by the men. Explain where you are, what you are doing, what your condition is and express how you feel physically and mentally.
