Crossing the Greenland ice cap by foot still is one of the biggest challenges in modern exploration. This feat was first achieved by Norwegian Polar explorer Fridtjof Nansen in 1888. To commemorate his achievement, a group of 5 explorers and one guide will attempt to relive this remarkable journey starting in May.
Heavy sea ice conditions have thwarted a science mission from reaching the Larsen C Ice Shelf in Antarctica from which a large iceberg broke off in July 2017. A team of scientists, led by the British Antarctic Survey (BAS), are on board the RRS James Clark Ross. Sea ice, up to 4-5 metres thick, made progress for the ship very slow and the ship’s captain made the difficult decision not to continue.
Penguins preserve records of Antarctic environmental change. The birds’ feathers and eggshells contain the chemical fingerprints of variations in diet, food web structure and even climate, researchers reported recently at the 2018 Ocean Sciences Meeting.
Australia has made its largest deposit into the global seed vault in Svalbard, Norway, as part of the 10th anniversary of the facility dubbed the "Doomsday Vault". In February 2018, more than 30 crates containing 34,000 different types of grain and pasture seeds were delivered to one of the most remote places on Earth for safekeeping.
The UK government is committed to the long-term protection of over four million square kilometres of the world oceans that fall within the UK’s Overseas Territories. Prioritising which parts of the ocean are most important to protect depends on scientific information to help decide upon the size and location of these marine protected areas (MPAs). However, many of the UK Overseas territories such as the sub-Antarctic island of South Georgia are very remote and have limited scientific data. Very often habitat maps made using large-scale physical environmental data (such as depth, submarine terrain and water temperature) are used to help predict patterns in marine biodiversity where biological records are either poor or lacking.
Researchers have measured a new world record: Small ice algae on the underside of the Arctic sea ice live and grow at a light level corresponding to only 0.02 percent of the light at the surface of the ice. Algae are the primary component of the Arctic food web and produce food far earlier in the year than previously thought.
Global ozone has been declining since the 1970s due to human-made chemicals. Since these were banned, parts of the ozone layer have been recovering, particularly at the poles. However, new research, recently published in the journal Atmospheric Chemistry and Physics, showed that the bottom part of the ozone layer at populated, lower latitudes is not recovering. The exact cause is currently unknown.
More than 70 percent of the global King penguin population, currently forming colonies in Crozet, Kerguelen and Marion sub-Antarctic islands, may be nothing more than a memory in a matter of decades, as global warming will soon force the birds to move south, or disappear. This is the conclusion of a study published in the current issue of the prestigious journal Nature Climate Change and performed by an international team of researchers from France, Monaco, Italy, Norway, South Africa, Austria and US.
In many areas of the Russian Arctic, the silent witnesses of the Soviet era are waiting for their removal. Thousands of tons of junk are still strewn all over the region of Murmansk. In a recent meeting, which was held in Murmansk the regional Parliament’s Ecology Committee has raised the discussion about state funding to remove this hazardous materials.
The changes faced by Arctic animals due to the global warming are huge. Loss of sea ice, increasing temperatures, invading species, and dietary changes pose a considerable threat to the iconic polar bear and other marine mammals like beluga whales. This high Arctic whale species spends its summers foraging the Arctic Ocean. Now they have to dive deeper and longer to find food compared to earlier years according to a new study by scientists from the University of Washington.
