Abstract Glacier mass loss is a primary contributor to sea‐level rise. All prior assessments assume all glacial melt water reaches the ocean, but many mountain glaciers are located far from oceans and may be affected b...

Glaciers in the northern Patagonian Andes (35-46°gS) have shown a dramatic decline in area in the last decades. However, little is known about glacier mass balance changes in this region. This study presents a geodetic ...

Abstract Warming climate has greatly affected the stability of the world’s glaciers. In 1957, as part of the International Geophysical Year, nine North American glaciers were surveyed in great detail so that they could...

Alaska and the Inside Passage offer a breathtaking journey through some of the most spectacular landscapes on Earth. This captivating region is renowned for its towering glaciers, majestic fjords, and abundant wildlife, ...

Glaciers are important water reservoirs and are extremely sensitive to the effects of climate change. The Manso River basin, in Northwest Patagonia, Argentina, is a typical hydrological system with actively retreating gl...

he Karakoram mountain range harbors the greatest concentration of glaciers and permanent snowfields outside the polar regions, making seasonal snowmelt the cornerstone of freshwater availability for the Indus River syste...

Observations show that glaciers around the world are in retreat and losing mass. Internationally coordinated for over a century, glacier monitoring activities provide an unprecedented dataset of glacier observations from...

The Desert Andes contain >4500 ice masses, but only a handful are currently being monitored. We present the mass changes of the small mountain glacier Agua Negra (1 km2) and of the rest of glaciers in the Jáchal river b...

Pio XI glacier, with an area of 1263 km 2 and a length of 65.7 km, is the largest of the Southern Patagonia Icefield (SPD. During the period 1945-1995 it experienced a net advance of ca. 10 km., a unique behavior conside...

The Andes Cordillera contains the most diverse cryosphere on Earth, including extensive areas covered by seasonal snow, numerous tropical and extratropical glaciers, and many mountain permafrost landforms. Here, we revie...

Expedition cruise vessels travelling to Antarctica offer several educational opportunities, with Citizen Science (CS) projects being the most prominent way to engage participants in polar science. FjordPhyto is a CS proj...

Climate change is altering temperatures and precipitation patterns all over the world. Melting glaciers increase surface run-off, thereby increasing the transport of suspended solids through streams. The increased load o...

The Pueyrredon-Posadas-Salitroso lacustrine system (PPS-LS) is located in the Andean Patagonia region of Argentina (47 220 2800S e 71 550 3400W) and represents a series of lakes formed as glaciers retreated during the...

Abstract Snow transport (wind drifting and avalanches) can concentrate a large amount of water into a relatively small area, in contrast to precipitation, which is spatially smoother. I develop a framework to constrain t...

The Sierra de Famatina is considered the highest elevation outside the Argentine Andes Cordillera, being the General Belgrano hill, 6097 masl, the main height. This altitudinal situation favored the development of glacie...

Abstract Glacier retreat transforms landscapes in polar and mountainous regions. Yet, the topography of the emerging terrain remains poorly known. Here, we present a physically consistent, global map of the ice-covered t...

Notochthamalus scabrosus (Darwin 1854) is commonly attached to littoral rocks and shells, often associated with Notobalanus flosculus (Darwin 1854), and sometimes with Chthamalus cirratus (Darwin 1851). Notochthamalus sc...

In many mountain ranges of the world, glaciers provide water from melt to rivers. Also, glacier-fed rivers receive different tributaries that differ in turbidity and canopy. In this scenario, we performed a field study...
