Far northern rivers are discharging increasing amounts of freshwater into the Arctic Ocean, due to intensified precipitation caused by global warming, say researchers at the Hadley Centre for Climate Prediction and Research in the United Kingdom.

Water exchange between the ocean, atmosphere, and land is called the global hydrological cycle. As Earth’s climate warms, the rate of this exchange is expected to increase. As part of this process, high-latitude precipitation and, c

Some anticipated the ’collision of the century’: the vast, drifting B15-A iceberg was apparently on collision course with the floating pier of ice known as the Drygalski ice tongue. Whatever actually happens from here, Envisat’s radar vision will pierce through Antarctic clouds to give researchers a ringside seat.

A collision was predicted to have already occurred by now by some authorities, but B-15A’s drift appears to have slowed markedly in recent days,

Recent studies have found that large, old and oily groundfish are significantly more important than their younger counterparts in maintaining healthy marine fish stocks – the larvae from their eggs better resist starvation and have a much greater chance of survival.

These same big, old fish are also routinely sought by fisherman, scientists say, and the age decline in fish populations helps to explain the collapsing fisheries off the Pacific Northwest coast. Other research also

An unprecedented flash observed by the space shuttle Columbia crew in 2003 over the Indian Ocean may be a new type of transient luminous event, like lightning sprites, but one that is not necessarily caused by a thunderstorm. The discharge was observed less than two weeks before the shuttle was lost during its Earth reentry.

The authors describe the discharge as a Transient Ionospheric Glow Emission in Red, or TIGER, event. It was recorded by a video camera in the near-infrare

Along with Ireland and Portugal, Norway is now working to make marine research a priority focus of the 7th EU Framework Programme for Research and Technology Development (2007–2010). The goal is to develop a vital, beneficial marine and maritime economy in Europe with the help of interdisciplinary research.

Seafood, transport, security, recreation and ecology are important key words for the ocean theme in Europe. Oceans encircle a great deal of the continent. This has played a cru

Risks of underground expansion often poorly studied; modeling floods, tsunamis essential to planning

The rapid and extensive underground expansion of mega-cities – for subways, malls, parking and public utilities – takes place often with too little knowledge of associated risks and too few plans to minimize the effects of a natural disaster, United Nations University experts warn.

With growing land pressures in cities (which contain about 50% of all people today, see
