Following straight on from the Patagonia expedition I headed down to Antarctica where I worked onboard MV Ultramarine for Quark Expeditions. I worked 3 consecutive voyages as Lead Mountain Safety Guide. The first voyage we headed over the the East of the Peninsula which was a quieter experience and the terrain there is older and more primal.
The Antarctic tourism sector is growing still at an exponential rate. There is little if any requirement for certified staff, though industry accidents have driven training and the need to prove competence. One of the roles is identifying glacial terrain and then marking a safe area of travel. The Antarctic Penisula is slightly more complex in that snow features can appear as a glacier (and to all intents should be treated as such).
