A world-class diver with twenty-five instructor ratings plus commercial and technical diving qualifications, Kelvin over-wintered in Antarctica as Field Diving Officer for the British Antarctic Survey in 2007. Managing the only scientific diving programme that consistently dives throughout the Antarctic winter allowed Kelvin to participate in several hundred dives in this challenging environment.

Expedition diving enables Kelvin to dive all over the world, on every continent and in every ocean. He has explored polar seas to tropical reefs with high definition cameras and ROV technology, and solo-dived locations probably never previously visited. His clients include European and American expedition companies as well as National Geographic photographers, BBC producers and French television presenters whom he advises on equipment, filming / diving techniques and wildlife.
Whether hiking through African bush or across Arctic tundra, diving with Chilean fur seals or snorkelling with British Basking sharks, his enthusiasm for nature in all its forms is infectious and educational. Working in collaboration with Dr. Sylvia Earle’s SEAlliance Foundation, he contributes video footage and stills images to the Ocean layer of Google Earth, whilst also sourcing and mentoring other contributors. Kelvin enjoys regularly writing on wildlife and its conservation for magazines and blogs.

Prior to working for BAS, Kelvin was Education Officer for the Whale and Dolphin Conservation Society. In addition he is an ardent advocate for sharks and has dived with several species of these much-misunderstood animals. Kelvin has also worked as a marine survival instructor for an internationally renowned training facility, and has extensive first aid, medic and hyperbaric chamber qualifications at responder and instructor level.

Kelvin lives in his native Scotland – a place he still insists has some of the best diving and marine life in the world.
