Scientists Find Nitrogen Ice Glaciers on Pluto

13 August 2015, by

Newly released close-up photographs from NASA’s New Horizons mission show evidence of exotic ice flow across dwarf-planet Pluto’s surface, indicating that Earth may not be the only planet with glacier-like geology. New Horizon’s Long-Range Reconnaissance Imager (LORRI) shows close-up photos of a sheet of ice that appears to have glided across Pluto’s surface in similar manner […]

El Niño is Melting Glaciers, Flooding California

11 August 2015, by

Recent research has suggested an increasingly important role between the pacific decadal oscillation (PDO) and the El Niño Southern Oscillation (ENSO) on natural phenomena around the globe, including glacial melt variability. These relationships are particularly strong when the PDO and ENSO are in-phase, as they are now. One study by Bijeesh Kozhikkodan Veettilab, Nilceia Bianchinic, […]

Roundup: Tidewater Glaciers, North Cascades, Antarctic Bacterium

10 August 2015, by

The Culprit for Greenland Ice Sheet Mass Loss “Overall mass loss from the Greenland ice sheet nearly doubled during the early 2000s resulting in an increased contribution to sea-level rise, with this step-change being mainly attributed to the widespread frontal retreat and accompanying dynamic thinning of tidewater glaciers. Changes in glacier calving-front positions are easily […]

Photo Friday: Through the Lens of a Tajikistani Glaciologist

7 August 2015, by

Earth scientists and glaciologists often have the opportunity to explore and witness Earth’s glaciers and geological landscapes through fieldwork. This Tajikistani glaciologist, Dr. Farshed Karimov, a professor at the National University of Tajikistan, recently published a presentation on glacial dynamic modelling. In it, he included stunning photos from his travels, mainly of the Pamir Mountains, […]

Volcanoes and Glaciers Shape Alaskan Landscape

6 August 2015, by

Volcanic eruptions mark the beginnings of new landscapes. Ash and lava cover existing vegetation and map out a fresh terrain. Though researchers understand how volcanic landscapes evolve over centuries, there is little understanding of how volcanic eruptions have influenced the geomorphology, or the relationship between the Earth’s surface and geological structures, according to Christopher F. Waythomas, from […]

What Do Black Southern Cod Like to Eat?

4 August 2015, by

In the freezing waters of Patagonia, southern Chile, the black southern codfish takes what it can get. With different levels of salinity and nutrients at the mouths of fjords and channels, the black southern codfish maintains regional feeding habits, a new study has found. Researchers Matthias Hüne and Rodrigo Vega, from the Institute of Ecology […]

Looking at Turkish Glaciers through Satellites

28 July 2015, by

More than half of the ice cover in Turkey has vanished since the 1970s, a mountainous country with an average elevation of 1,132 meters above sea level. Half of Turkey is covered by mountains and hills. Glaciers now exist on three volcanoes, in the high peaks in the Southeastern and Middle Taurus Mountains, and in […]

Tracking Glaciers & Rivers in Bhutan

23 July 2015, by

Less than a decade back Bhutan transitioned from an absolute monarchy to a democracy. Although right to information was enshrined in their constitution, availing reports and info concerning glaciers, health of rivers and status of hydropower projects remains a challenge to this day. Most government reports are neither published, nor readily uploaded on to websites, […]

Alaska Mountain Glaciers Raise Global Sea Level

22 July 2015, by

Alaska’s impact on global sea level rise is becoming more pronounced. Its melting glaciers, particularly the minority mountain glaciers, will be a major driver of sea level change in the coming decades, according to a new study conducted by Chris Larsen, research associate professor at the University of Alaska Fairbanks, and his colleagues. With over […]

Roundup: State of Glaciers and Glacier’s End Nature Preserve

20 July 2015, by

2014 State of the Climate: Mountain Glaciers “In 2014, glaciers continued to shrink. Based on an analysis of more than three dozen reference glaciers with long-term monitoring, the 2014 BAMS State of the Climate reports that in 2014, glaciers experienced an average loss of 853 millimeters of water equivalent, meaning the equivalent depth of water […]

Iceberg Calving Boosts Methane Emissions

16 July 2015, by

The substantial increase in methane concentrations in tropical wetlands can be attributed to the last Glacial Period, when icebergs calving off North America introduced massive influxes of fresh water into the North Atlantic, new research shows. Calving of glaciers in the North American ice sheet, also known as Heinrich events, released large icebergs into the […]

Melting Exhibit Brings Glaciers to London

14 July 2015, by

The Summer Science Exhibition’s “Vanishing Glaciers” exhibit, an interactive exhibit focusing on the science of observing and predicting glacial mass balance, hydrology, and dynamics, as well as the impact of climate change on vital water sources, concluded Sunday July 5, marking the end of the annual science festival. The Summer Science Exhibition, produced by the […]
