Sponge fossils and local cooling: Three Czech discoveries from Antarctica
Since 2007, the Czech Antarctic Programme has made a number of discoveries on Antarctica.

From the convolutions of frozen rivers to the concentration of plankton and sediment, from the advance of a glacier to the symmetry of ice, satellite images of the polar regions offer a breathtaking spectacle.
The scientific team of the SWAIS 2C project has successfully completed the first stage and recovered the first sediment cores.
A process that was further developed for practical applications by two research groups at the ZHAW means that water stored in liquid form at temperatures as low as -120 °C can be used to develop life support systems for extreme environments, which could be of great interest to polar stations and communities in the future.
A satellite antenna has just been installed at Union Glacier Camp by ALE. The data collected will be used to provide more accurate and reliable weather forecasts for Antarctic expeditions and programs managed by the company.
The crew of the Sea Shepherd vessel “Allankay” recently documented how six supertrawlers sailed through a large group of hundreds of feeding whales to catch huge amounts of krill.
The release period after the breeding season can quickly resemble a sea voyage where the penguins have to choose one route over another… a story of compromise.
Four emperor penguin colonies have been discovered thanks to satellite images. These colonies, identified for the first time, each number fewer than 1 000 pairs.
The cooling of relations between the West and Russia is having a major impact on the study of changes in the Arctic, affecting the ability to monitor climate change.
The loss of sea ice in the Arctic is one of the most visible signs of our rapidly changing climate. Real Ice now wants to counteract the melting ice.
The eroding riverbank is unpredictable, and families are forced to move to other exposed areas to continue their subsistence farming.
A new laboratory module is currently being installed at the Argentinian Antarctic station Esperanza, which aims to produce green hydrogen soon and replace the diesel generators.
Why are microplastics found in the polar regions almost exclusively in fibre shape? The latest experiments and simulations provide the answer: fibres can be transported much further in the atmosphere than particles with a different shape.
Global warming may be disrupting the polar vortex causing cold air outbreaks in southern parts of the world.
An operation to deliver supplies and transfer polar researchers to the “North Pole-41” drift station was successfully carried out in the Arctic Ocean.
Analizing ice cores shows that heavy metals have been transported to the heart of Antarctica from both geographically and temporally distant regions.
The unprecedented heatwave that hit East Antarctica almost two years ago could be traced back to an intense atmospheric river from lower latitudes.
To monitor the melting of the Antarctic and its effects on the balance of the Southern Ocean, a Spanish-Canadian association is installing a measuring point next to the Spanish Juan Carlos I base. It transmits data by satellite from the Antarctic Peninsula.
By 2100, the acidity of Antarctic coastal waters could double. A threat to ecosystems and animal life in the Southern Ocean.
First announced last spring of the southern hemisphere, highly pathogenic avian influenza HPAI is now affecting five of the 14 species tested in South Georgia. A few suspected cases near the Antarctic Peninsula suggest that the disease is still spreading.
Despite the strong seasonal fluctuations in living conditions in the Arctic, the animals living on the seabed of the Arctic Ocean are largely unaffected by the seasons.
India has decided to build a new research station in Antarctica to replace the “very old” predecessor station Maitri. Commissioning is planned for 2029.
Southern elephant seals don’t fast completely during the drastic moulting period, but they may well go into the water, drink and perhaps even hunt, contrary to what has been established so far.
The Polar Issues Chair led by Anne Choquet and Brest’s maritime higher education courses looked at the profession of polar guide, at the heart of the controversy surrounding tourism in the Arctic and Antarctic.
