In her new exhibition, Melt Down - Climate Change In The High Arctic, celebrated photojournalist and Arctic specialist Louise Murray highlights the dramatic melting of the ice sheets in the Arctic through a series of beautiful photographs. We have an exclusive gallery of images from the exhibition below.

Louise is a self-confessed polar nut with 15 years of experience as a professional, she spends much time plotting her next visit to the high north.

A lover of the Arctic environment both above and below the water, Louise has travelled to the Svalbard area several times, to the rarely visited Franz Josef land in Russia, to northern Greenland, and extensively to Nunavut. She has a special interest in the environmental issues particular to this very special region.

Despite her obsession with the Arctic, Louise has worked in many other areas of travel and wildlife. Louisemurray.com showcases work from around the world, from extreme locations such as deserts and rainforests to wildlife ranging from tigers to sharks.

Louise's images have appeared in many publications worldwide including The Times, the Guardian, Geographical, BBC Wildlife and Focus among others in the UK, many magazines throughout Europe and as far afield as China. She is one of the most experienced still photographers specialising in the high Arctic.

She leads expeditions to the high north for Arctic Kingdom Marine Expeditions, helping film crews and professional photographers achieve their goals safely in this often difficult environment. Working both above and below the waters of the Arctic Ocean, assisting and ensuring the safety of participants is paramount.

Louise has worked with documentary and wildlife film crews from National Geographic, Galatee, Brazil and the BBC.

The challenges are above and beyond coping with travelling in such a hostile environment: "Logistics can be mind-boggling as we charter helicopters, twin otters, 737's and Hercules transports to get the crew's gear in place. And move airboats, zodiacs, snowmobiles and qamotiqs over ice with people and supplies. Working with the Inuit people is for me the most rewarding part of the job and I now count many as friends."
