Angela Morelli is an Italian information designer based in London. Her love of mathematics led to an engineering degree from the Politecnico of Milan. Her love of design led to a long journey through industrial, communication and information design. Her love for the planet led to a strong passion for global water issues. Her love for science led to dialogues and collaborations with research and commercial organisations in Europe.

She believes that bringing about change is not an easy task and it can only follow from a true understanding of a problem, from awareness and reflection. Design has a vital, irreplaceable role to play in achieving this understanding through empathic thinking and emotional intelligence.

AWESOME SCIENCE!: TOP VIDEOS FROM LAST NIGHT’S (JAN. 24, 2012) STUNNING NORTHERN LIGHTS SHOW

For the last few days, Earth has been bombarded with radiation as the strongest solar storm since 2005 raged. This geomagnetic storm has resulted in a wealth in stunning videos of the northern lights. The lights were most vibrant in northern Europe, but did reach into Canada and Alaska.

Some of the videos on this site you can enjoy!:

SATELLITES DETECT ABUNDANCE OF FRESH WATER IN ARTIC

Rising seas in Arctic Ocean (CPOM/UCL/ESA/Planetary Visions)
23 January 2012

ESA satellites show that a large dome of fresh water has been building up in the Arctic Ocean over the last 15 years. A change in wind direction could cause the water to spill into the north Atlantic, cooling Europe.

The results are remarkable: since 2002, the sea surface in the studied area has risen by about 15 cm, and the volume of fresh water has increased by some 8000 cubic km – around 10% of all the fresh water in the Arctic Ocean.
Researchers from the Centre for Polar Observation and Modelling (CPOM) at University College London and the UK’s National Oceanography Centre used data from ESA’s ERS-2 and Envisat satellites to measure sea-surface height over the western Arctic from 1995 to 2010.

The results were published yesterday in the online version of the scientific journal, Nature Geoscience.

The scientists conclude that the dome could be a result of strong Arctic winds accelerating a large ocean circulation known as the Beaufort Gyre, causing the sea surface to bulge.

A change in the direction of the wind would cause the fresh water to spill into the rest of the Arctic Ocean and even reach the north Atlantic.

This could slow a key ocean current, stemming from the Gulf Stream, and subsequently cool Europe.

This current keeps the continent relatively mild compared to other areas at similar latitudes.

“When we looked at our data on a year-to-year basis, we noticed that the changes in the sea surface height did not always follow what the wind was doing, so we thought about reasons why this might happen,” said Katharine Giles, CPOM research fellow and lead author of the study.

“One idea is that sea ice forms a barrier between the atmosphere and the ocean. So as the sea ice cover changes, the effect of the wind on the ocean might also change.

“Our next step is to look into how changes in the sea ice cover might affect the coupling between the atmosphere and the ocean in more detail to see if we can confirm this idea.”

Sea ice can be measured by different types of satellite data. Radar altimeters on satellites such as the two used in the study, Envisat and ERS-2, can be particularly useful when observing inaccessible areas like the Arctic.

Envisat, the largest Earth observation satellite ever built, will mark 10 years in orbit in March.

ERS-2 was retired in July 2011, but 20 years of data from it and predecessor ERS-1 on oceans, land, ice and atmosphere will continue to be used by scientists for years to come.

“We were able to produce the Beaufort Gyre results thanks to the overlap of the ERS-2 and Envisat missions and long-term satellite data availability,” said Seymour Laxon, director of CPOM and co-author of the paper.

ESA will continue to monitor the Arctic with the upcoming Sentinel series of Earth-observing satellites for Europe’s Global Monitoring for Environment and Security (GMES) programme.

Later this year, the first results of seasonal changes in sea-ice thickness from data acquired by ESA’s CryoSat-2 satellite will be presented.
