  • On 6th December the SA Agulhas, a team of British explorers, set off from London to conquerthe last great polar challenge: to cross the Antarctic continent in winter using the exact sameequipment as the first explorers did in 1820. Their remarkable attempt aims to raise $10m forSeeing is Believing and provide essential scientific data about this frozen wilderness. But willthis expedition really be beneficial? Or is it just a case of ‘British Bravado’?Antarctica is one of the world’s most extreme environments. It is a 2000 mile journey to travelacross the continent and has for many years been considered too dangerous to try, but theexpedition team will have to overcome this hostile and extreme environment if they want tosucceed. On the polar plateau, temperature is controlled by solar input, latitude and altitude,The high altitude and remoteness from the warming effects of the ocean also maketemperatures colder, so The climate of the south pole has a range of -80.6°C as the minimumand -13.6°C as the maximum temperature. Snowfall is light due to distance from the ocean. TheAntarctic is mainly a large sheet of ice covering a collection of small islands, this ice sheet has athickness of 2,160m. Antartica has a average wind speed of 9.99 ms-1 which is rather calm incomparison with other coastal environments.If you were to compare the Antarctic to another extreme environment, such as the Saharadesert, they share similar features that contribute to their extremity. They both have inhospitabletemperatures, high altitude levels in selected areas and are home to organisms that are adaptedto their specific climate, terrain and latitude. and could not survive anywhere else. Althoughthese two environments are very diverse, they are both deserts but at opposite ends of theThe team aims to provide scientific data about the Antarctic during their travel. They aim todetermine the potential diversity of extreme psychrophilic (cold-loving) bacteria in Antarcticsnow, this is for biotechnological research purposes. Also, they aim to map ,with centimeterprecision, the surface shape of the Antarctic Ice Sheet, along the 4,000 km expedition track.Using GPS receivers and range sensors fitted to the Science Caboose. This is for scientistswho require profile data to allow them to develop better models required for predicting the futureeffects of climate change on Ice sheets (e.g. validation of ice mass balance models). Those are2 of the projects they have set for themselves.The expedition also aims to have charitable benefits. Their chosen charity is called ‘Seeing isBelieving’. It is collaboration between the International Agency for Prevention of Blindness andStandard Chartered. Together they have set the ambitious target of raising $100m by 2020 andTCJ aims to be a major contributor ,of $10m, to this total.In conclusion, I think TCJ is very beneficial for the geographical and scientific world because itwill provide up-to-date information about Antarctica, with this new data it will help to us to furtherunderstand how pollution and climate change is changing this delicate environment and the lifeforms that dwell upon it and hopefully helping us to protect the South pole. Furthermore, withthe money the expedition provides it will change the lives of blind people across the world. I doalso feel this is for ‘British Bravado’ because they aim to do it using the exact same equipmentas the first explorers did in 1820, and in doing so establishing Britain as the greatest nation ofexplorers.By Asiyah Sadak 
