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

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

May glaciers and sea ice ecosystems on Earth be analogues to icy planets and moons? (Czy lodowce i lód morski na Ziemi mogą być analogią do księżyców i planet pokrytych lodem?)

The Earth is not the only celestial body in the universe partially covered with ice. To focus on Earth’s glaciers as a habitat that can be similar to glaciers on other moons and planets has been of interest to astrobiologists for several years. Whoever has seen Christopher Nolan’s “Interstellar” should probably remember the icy planet … Continue reading

Mosses hidden under glaciers for six hundred years are back to life (Mchy ukryte 600 lat pod lodem wróciły do życia)

In polar regions, mosses present one of the most numerous groups with respect to species diversity. Additionally, they constitute the greatest biomass of plants. They are both a habitat for a number of invertebrates and the main source of food for them (e.g. tardigrades, mites or springtails). Mosses are well-known for their high phenotypic plasticity … Continue reading

Snow microalgae may be used in industry (Glony śnieżne mogą zostać wykorzystane w przemyśle)

Algae may be used as a food and bio-fuel in the near future.  Snow algae may be the key to culturing these economically important organisms at low temperatures, thus reduce general costs of production. Scientists from Norway and Netherlands published paper in Bioresource Technology and provided information on culturing of microalgae collected from Svalbard archipelago. … Continue reading

Why snow melts in Antarctica? (Dlaczego śnieg topnieje w Antarktyce?)

  A team led by professor Andrew Hodson from the University of Sheffield sought to find an answer to the following question: why does snow melt so fast in the Antarctic? The team has conducted research on Livingston Island, investigating the maritime Antarctic and examining the relationship between microbial communities and snow habitats. The nutrients … Continue reading
