An evaluation of snowline data across New Guinea during the last major glaciation, and area-based glacier snowlines in the Mt. Jaya region of Papua, Indonesia, during the Last Glacial Maximum
Geomorphological mapping and lake-core data from Mt. Jaya, western New Guinea, show that Last Glacial Maximum (LGM) glaciation was less extensive than previously thought. Average equilibrium line altitudes (ELAs), calculated using the area-altitude-balance ratio method, for minimum and maximum ice configurations were 4050±49 and 4000±56 m a.s.l., respectively. This is about 600 m below the ELA of the Mt. Jaya glaciers in 1971-73 and ca 400 m higher than values previously quoted for LGM ELAs in...[Show more]
