Research Cruise To Understand Major Changes In Atlantic

11.05.2005


Scientists at the University of Liverpool are embarking on a research cruise to help them understand recent major changes in the temperature of the Atlantic.



Researchers at the University’s Department of Earth and Ocean Sciences have been examining why ocean temperatures are rising within the tropics and mid-latitudes of the North Atlantic, but at the same time are decreasing at the ocean’s high latitudes.

The research team, which also includes scientists from the National Oceanography Centre, Southampton and the University of East Anglia, are departing on a research cruise from Bermuda to establish the extent of the most recent temperature changes. Scientists will be assessing the temperature of the ocean at different depths and collecting water samples to identify levels of carbon dioxide in the ocean.


Professor Ric Williams, who is leading the study at the University of Liverpool, explains: “Our research indicates that the temperature changes in the Atlantic are influenced by changes in the atmospheric jet stream over the Atlantic. The jet stream changes in strength, influencing both the weather and the state of the oceans.

“Since the early 90s, the jet stream has been stronger, leading to stormy, wet weather in the UK. We also think this jet stream has led to the major temperature changes we are seeing in the Atlantic.

“What we don’t yet know is how much can be linked to the greenhouse effect and how much is down to a natural phenomenon – we don’t, for example, know if atmospheric changes in carbon dioxide could influence the path and strength of the jet stream.

“The data we collect from the research cruise will shed more light on why these changes in the ocean are taking place and help us assess what the implications might be for the environment and future generations.”

Dr Elaine McDonagh from the National Oceanography Centre is leading the cruise. The research is funded by the Natural Environment Research Council (NERC).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
