Evolution of the Antarctic ice sheet

This item was filled under Climate
A new light has been shed on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between glacial and interglacial periods, which significantly slows down the response of the ice sheet to climate change....

Potential of seagrass to combating climate change

This item was filled under Climate
Seagrass ecosystems could play a key role in combating climate change, researchers have discovered. The marine flowering plant also helps sustain abundant sea life and protects shorelines around the world from coastal erosion. Yet with seagrass habitats suffering rapid global decline and despite the plant's huge potential; there are currently no functioning seagrass restoration or conservation projects. Due to their shallow coastal habitat the aquatic plant is particularly prone to human disturbance - globally 24 per cent of seagrass species are now classified as threatened or near threatened....

Climate engineering may save coral reefs, study shows

This item was filled under Climate
Mass coral bleaching, which can lead to coral mortality, is predicted to occur far more frequently over the coming decades, due to the stress exerted by higher seawater temperatures. Geoengineering of the climate may be the only way to save coral reefs from mass bleaching, according to new research....

Estuaries protect Dungeness crabs from deadly parasites

This item was filled under Climate
Parasitic worms can pose a serious threat to the Dungeness crab, a commercially important fishery species found along the west coast of North America. The worms are thought to have caused or contributed to the crash of the crab fishery of central California during the last half century. New research shows that infected crabs can rid themselves of parasites by moving into the less salty water of estuaries. Low salinity kills the worms creating a parasite refuge for the crabs....

3D geological tour of the Guadalquivir basin using Google Earth

This item was filled under Climate
A research team has developed a tool that allows a 3D journey in ten sites of geological and palaeontological interest in the Guadalquivir basin (Huelva, Spain). In the virtual tour, developed with Google Earth, you can visit and explore treasures of this area, such as records of the opening of the Atlantic Ocean, using tablets and smartphones....

A multinational team of researchers who spent three and a half years sampling the ocean's sunlit upper layers aboard the schooner Tara unveil the first officially reported global analyses of the Tara Oceans consortium....

New insights into global ocean microbe-virus interactions, drivers of Earth’s ecosystems

This item was filled under Climate
Ocean microbes are vital to the Earth's ecosystems, and their interactions with ocean viruses can have dramatic effects on processes ranging from oxygen production to food supply. Marine biologists have now uncovered new information about the way marine viruses and microbes interact on a global scale, which may allow researchers to predictively model their complex interactions....

Sudden onset of ice loss in Antarctica so large it affects Earth’s gravity field

This item was filled under Climate
Scientists have observed a sudden increase of ice loss in a previously stable region of Antarctica. The ice loss in the region is so large that it causes small changes in the gravity field of the Earth....

Rapid action necessary to protect Malaysia’s sea cows and their habitat

This item was filled under Climate
Malaysia aims to protect 10% of its marine environment by 2020. Less than 1%, however, is currently protected. This may have dire consequences for the country's endangered dugong population, warn a team of Malaysian scientists....

Surviving harsh environments becomes a death-trap for specialist corals

This item was filled under Climate
The success of corals that adapt to survive in the world's hottest sea could contribute to their demise through global warming, according to new research....
