Introverts prefer mountains
In a series of three studies, researchers tested whether there is a link between personality and an aspect of physical ecology: flat terrain versus mountainous terrain. The study found that only one of the Big Five personality traits predicted terrain preference -- extraversion.

Sun has more impact on the climate in cool periods
The activity of the Sun is an important factor in the complex interaction that controls our climate. New research now shows that the impact of the Sun is not constant over time, but has greater significance when the Earth is cooler.

Submarine data used to investigate turbulence beneath Arctic ice
Using recently released Royal Navy submarine data, researchers have investigated the nature of turbulence in the ocean beneath the Arctic sea-ice. Recent decreases in Arctic sea ice may have a big impact on the circulation, chemistry and biology of the Arctic Ocean, due to ice-free waters becoming more turbulent. By revealing more about how these turbulent motions distribute energy within the ocean, the findings from this study provide information important for accurate predictions of the future of the Arctic Ocean.

Strait of Georgia: Salish Sea seagull populations halved since 1980s
The number of seagulls in the Strait of Georgia is down by 50 per cent from the 1980s and researchers say the decline reflects changes in the availability of food.

'Ecosystem services' help assess ocean energy development
Environmental scientists suggest that the way to fill vast gaps in knowledge about the ecological and socioeconomic impacts of ocean energy development is to consider how the benefits provided by ocean ecosystems change before and after the placement of ocean energy infrastructure.

IPCC sea-level rise scenarios not fit for purpose for high-risk coastal areas
The sea-level rise scenarios of the Intergovernmental Panel on Climate Change (IPCC) do not necessarily provide the right information for high-risk coastal decision-making and management, according to new research. A commentary warns that the IPCC scenarios are often inappropriate or incomplete for the management of high-risk coastal areas as they exclude the potential for extreme sea-level rises. This missing information is also crucial for a number of policy processes, such as discussions by G7 countries to establish climate insurance policies and allocations of adaptation funding by the Green Climate Funds.

Coral disease linked to a warming Atlantic
Over the last four decades, the iconic elkhorn and staghorn corals that dominated Caribbean reefs for millions of years have all but disappeared. According to a new study, ocean warming has played a significant role in this dramatic decline.

Ocean circulation change: Sea level spiked for two years along Northeastern North America
Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed. The unusual spike in sea level caused flooding along the northeast coast of North America and was independent of any hurricanes or winter storms. A new article documents that the extreme increase in sea level rise lasted two years, not just a few months.

Massive amounts of Saharan dust fertilize the Amazon rainforest
Every year, millions of tons of nutrient-rich Saharan dust cross the Atlantic Ocean, bringing vital phosphorus and other fertilizers to depleted Amazon soils. For the first time, scientists have an accurate estimate of how much phosphorus makes this trans-Atlantic journey.

Ocean acidification slows algae growth in the southern ocean
Scientists demonstrate for the first time that ocean acidification could have negative impacts on diatoms in the Southern Ocean. In laboratory tests they were able to observe that under changing light conditions, diatoms grow more slowly in acidic water.

Looking back into the past of oceans: Acidification trends, seasonal fluctuations
Using cutting edge technologies researchers were able to reconstruct pH values of the Northern Pacific with a high resolution since the end of the 19th century. The study reveals a clear acidification trend, but also strong seasonal fluctuations.

Bacteria in marine sponges harvest phosphorus for reef community
Significant accumulations of polyphosphate granules have been found in three common sponge species of the Caribbean coral reef, indicating that microorganisms that live on marine sponges are pulling phosphorus out of the water to feed themselves and survive in a deep-water environment where very few nutrients are available. This finding has important implications for understanding how phosphorus is sequestered and recycled in a reef environment.

Scientists bring oxygen back to dead fjord
More and more of the world's waters are seriously lacking oxygen. Could we use pumps to bring oxygen and thus higher life back into these waters? A Danish/Swedish research team says yes. They installed pumps in a Swedish fjord that showed a strong oxygen deficit and now they report that all the right oxygen-loving organisms have come back to the fjord.

Greenland is melting: The past might tell what the future holds
Scientists have managed to quantify how the Greenland Ice Sheet reacted to a warm period 8,000-5,000 years ago. Back then temperatures were 2-4 degrees C warmer than they are in the present. Their results are important as we are rapidly closing in on similar temperatures.

Global impact of debris on marine life studied
Nearly 700 species of marine animal have been recorded as having encountered humanmade debris such as plastic and glass according to the most comprehensive impact study in more than a decade.

Global warming to increase ocean upwelling, but fisheries impact uncertain
A new report suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will cause major changes in marine biodiversity.

Humans altering Adriatic ecosystems more than nature, study shows
The ecosystems of the Adriatic Sea have weathered natural climate shifts for 125,000 years, but humans could be rapidly altering this historically stable biodiversity hot spot, a new study shows.

Mapping seascapes in the deep ocean
A new, automated method for classifying hundreds of kilometres of the deep sea floor in a way that is more cost efficient, quicker and more objective than previously possible has been developed by researchers.

Satellite images reveal ocean acidification from space
Pioneering techniques that use satellites to monitor ocean acidification are set to revolutionize the way that marine biologists and climate scientists study the ocean. This new approach offers remote monitoring of large swathes of inaccessible ocean from satellites that orbit the Earth some 700 km above our heads.

Historic tide gauge data to shed light on ancient tsunamis
By restoring historic tide gauge data from Malta and making it available to the public, researchers hope to shed new light on past tsunamis and climate change in the Mediterranean.
