The Carpenter 1 fire burned approximately 11,000 ha in the Spring Mountain National Recreation Area (Humboldt-Toiyabe National Forest) near Las Vegas, Nevada between July 1, 2013 and its containment on August 18, 2013. The left side of the photo shows the fire affected arid desert scrub ecosystems at 1500 m (foreground) to subalpine pine ecosystems at 3400 m (background). The foreground of the pho ...[Read More]

This picture was taken in the Arctic in May 2018. It shows the unmanned marine vehicle Proteus in front of the tidewater glacier Conwaybreen in the Kongsfjorden in Spitsbergen in the Svalbard Archipelago. The front of tidewater glaciers is an almost vertical wall of ice standing over the sea where direct measurements are very critical due to the possibility of sudden fall of enormous blocks of ice ...[Read More]

Imaggeo on Mondays: Our QUEST for innovative tools to understand changing environments and climates

Sebastian Breitenbach and Adam Hartland June 10, 2019

A multi-year cave monitoring programme in New Zealand's Waipuna Cave focusses on developing novel quantitative proxies for palaeoclimatology. We measure drip rate, temperature, electrical conductivity and many other parameters, analyse the isotopic and elemental composition of the water, and compare our results with the length and origin of recorded rainfall. With our data, we hope to better understand the interplay of the El Nino-Southern Oscillation and the Southern Westerlies and the local response to changes in their dynamics. This monitoring is part of the EU Marie Curie RISE Project "QUantitative palaeoEnvironments from SpeleoThems – QUEST". Credit: Sebastian Breitenbach (distributed via imaggeo.egu.eu)

The photo shown here shows typical sampling work underground. You can see Ola Kwiecien and Cinthya Nava Fernandez, researchers at Ruhr University Bochum in Germany, collecting dripwater in New Zealand’s Waipuna Cave as part of a four-year EU-funded monitoring programme. Our research aims at developing innovative geochemical indicators that we can use to quantify changes in the hydrological system ...[Read More]

Roughly 50 million years ago, the Eurasian and Indian continental plates began to crash into each other, dramatically changing the landscape of modern-day Asia. The force of the collision caused the Earth to scrunch together at the zone of impact, subsequently forming the Himalayan mountain range. However, to the north of the crash, a stretch of the Earth uplifted without bunching up or wrinkling; ...[Read More]
