Mineral dust on the Greenland Ice Sheet originates even from distant tropical places (Pył mineralny na czapie lodowej na Grenlandii pochodzi nawet z dalekich tropikalnych miejsc)

Pollutants, microbes and dust are passively migrating along with the wind. This dust is important in the formation of cryoconite holes – water-filled reservoirs on the surface of glaciers. How does it work? Dark dust on ice is called cryoconite and it is transported along with the wind onto a glacier’s surface. Along with pigmented … Continue reading

EGU 2018 Session Announcement: Drivers and controls of life in glacial and ice-sheet environments

We invite abstract submissions for the above EGU 2018 session. The deadline for an abstract submission is 10 January 2018.  This session will encompass research on i) the regulation of biological communities by abiotic stressors, ii) the role of biotic interactions in sustaining and/or limiting life, and iii) psychrophilic adaptations permitting persistence in the cryosphere. Contributions … Continue reading

Helicopters as a source of recent black carbon in pristine Antarctic lakes (Helikoptery jako źródło współczesnego czarnego węgla w dziewiczych jeziorach antarktycznych)

In the recorded history, Antarctica is noted as the last region on Earth to be discovered and colonized by humans. More than 170 million years ago, Antarctica was part of  Gondwana – a supercontinent. Antarctica separated from Gondwana ca. 170 million years ago, and as we know it today was formed around 25 million years ago. Due to … Continue reading

Cyanobacteria – glacial ecosystems engineers. Do the same species live everywhere? (Cyjanobakterie – inżynierowie ekosystemów lodowych. Czy wszędzie żyją te same gatunki?)

  Can you imagine a particular species of bird or butterfly inhabiting forests in all the regions of our planet? Probably not… However, there are some micro-organisms which can exist in regions distant from one another. Cyanobacteria are a worldwide group of bacteria that obtain energy through photosynthesis, and thus they are responsible for oxygen … Continue reading

Anthropic contaminants are accumulated, stored and released from glaciers (Zanieczyszczenia cywilizacyjne są akumulowane, a następnie  uwalniane z topniejących lodowców)

Anthropic contaminants are accumulated, stored and released from glaciers (Zanieczyszczenia cywilizacyjne są akumulowane, a następnie uwalniane z topniejących lodowców)

Can you imagine the picks of the European Alps without glaciers? Such a dramatic scenario is likely to take place by the end of 2100. As a source of electric power, water for domestic use and a supply of water for downstream ecosystems mountain glaciers are of great importance. Currently, they are melting and release … Continue reading

Unexpected sources of iron for Antarctic marine ecosystems (Niespodziewane źródło żelaza dla ekosystemów morskich w Antarktyce)

What do you see when you think of iron? Probably bars, bridges, cars or plains. In general, the objects you can observe constitute some significant elements of a system we call industry and transport. This element however, is also essential to biological functioning of all organisms. It is crucial for a number of processes such … Continue reading

Bacteria on glaciers may degrade pesticides (Bakterie na lodowcach mogą degradować pestycydy)

At first glance, polar and high mountain regions appear as pristine and not contaminated areas, generally free from human impact. This illusion, however, was shattered by scientists a long time ago. Due to long-range wind transport, although far distant from their original sources, organic contaminants are present in both polar and mountain regions. They are … Continue reading
