This site uses cookies to assist with navigation, analyse your use of our services, and provide content from third parties. Variations in present-day glacier mass balance in the Southern Alps are largely attributed to changes in air temperature, due both to solar radiation and to turbulent heat flux from air masses passing over the ocean west of New Zealand; precipitation changes play a lesser role (Anderson and Mackintosh, 2006). New Zealand’s Southern Alps are best known for being the set for the Lord of the Rings and the Hobbit movies.

Co-author Dr. Andrew Lorrey is a Principal Scientist based at NIWA who was involved with the study. Charles Lyell was a pioneering geologist from Britain, who studied the underlying forces which shaped the earth’s surface to its present day form. The Southern Alps is the highest mountain range in Australasia, with Mount Cook’s summit standing at 12,218ft above sea level. The Lyell Glacier has been the combined flow from the easterly tributary near Rangiata Col (E) and a northern tributary, Heim Plateau (H). The main valley track continues through the bush to Neave Creek Hut passing Cave Camp at the Wilkinson river/Whitcombe River confluence. long, reaching almost to the foot of a basal remnant of a truncated yalley-side spur known as Mein's Knob and to within 800 m. of the snout of the Ramsay Glacier. In 2019, only 12% of ice mass remained in what was formerly the low altitude part of the Little Ice Age glacier region—also called the ablation zone—and much of the what used to be ice-covered in the Little Ice Age ablation zone is now completely ice free. The 2013 austral winter featured record warmth, and the early melt season has also been warm in New Zealand, the impact on this glacier can be assessed in March or April as the melt season ends. "Our findings provide a conservative baseline for rates of Southern Alps ice volume change since pre-industrial times.

Relative to recent decades, the Southern Alps lost up to 77% of their total Little Ice Age glacier volume. Not only do local communities depend on glaciers as sources of fresh water, hydropower and irrigation, but mountain glacier and ice cap melt presently accounts for 25% of global sea-level rise. Looking forwards, planning must be made for mitigating the decreased runoff to glacier-fed rivers because that affects local water availability, landscape stability and aquatic ecosystems.".
