H.E.A.R. / Himalayan Experiments in Acoustic Research

Scroll for information about our research & video clips

The team conducted scientific fieldwork and acoustic experiments on Drang-Drung Glacier and its periglacial lake, which is an unstudied glacial field-site, using a purpose-built ocean instrument (hydrophone sesnor) to monitor and record the sounds of glacial dynamics and lake expansion. Our underwater recordings will contribute data to glacier melt and risk assessments of flooding (Glacial Lake Outburst Flood, GLOF). Research on acoustic instrumentation to measure ice loss (Glowacki & Deane, UCSD Scripps Oceanography) informs this fieldwork. HEAR builds further capacity through the inclusion of post-graduate students who received training on glacier research during the expedition as well as in field data processing (meteorological and acoustic experiment data and GLOF risk assessment.
