Satellite images make it possible to monitor ice break-up in Torne River
SMHI has used high-resolution satellite images for the first time to monitor ice break-up in Torne River, one of Sweden’s largest unregulated rivers. The CryoLand research project has developed a method of identifying ice jams in the Torne River and flooded areas around the river using high-resolution satellite images. “Radar satellite images with a resolution of 1-3 metres can be ...

Coastal processes at Cartagena
During a visit to Cartagena de Indias, Colombia, the other week, Dr. Ulf Erlingsson of Lindorm, Inc. made some observations using a drone. The video below shows the interesting situation that is also visible on satellite images in Google Earth. This is the end of a coastal sediment transport and it ends in turbulence when an opposite direction current mixes with the high-turbidity nearshore ...

Scientists map penguins from space
Penguin poo (guano) stains, visible from space, have helped British scientists locate emperor penguin breeding colonies in Antarctica. Knowing their location provides a baseline for monitoring their response to environmental change. In a new study, published this week in the journal Global Ecology and Biogeography, scientists from British Antarctic Survey, (BAS) describe how they used satellite ...

Satellites can help preserve Earth`s biodiversity
To help preserve the biodiversity of our planet, ecologists should make more use of remote sensing and apply the knowledge of aerospace agencies like NASA and ESA. This according to an international group of remote sensing specialists in an article published today in Nature. 'This is extremely feasible given that more and more satellite images are being made available as open data,' says one of ...

‘Green’ growth needed to reach Kenya’s development goals – UN agency
An innovative United Nations atlas of Kenya using satellite images to pinpoint shrinking tea-growing areas, disappearing lakes, rising loss of tree cover and increased mosquito breeding grounds has highlighted the East African country’s need to invest in “green” development to escape from poverty. The new 168-page publication, released today by the UN Environment Programme (UNEP), shows how ...

Robotic glider to map Moreton Bay impacts
Dr Andy Steven from CSIRO's Wealth from Oceans Flagship says the glider’s deployment is part of a research program to monitor the extent of the flood plume into Moreton Bay and assess its effects. “This disastrous flood also provides us with a rare opportunity to understand how our marine ecosystems respond to massive inputs of fresh water and sediments,” Dr Steven says. ...

Satellites helping aid workers in Honduras
Humanitarian aid workers responding to devastating flooding in Honduras have received assistance from space, with satellite images of affected areas provided rapidly following activation of the International Charter on Space and Major Disasters. Tens of thousands of people have been displaced and 33 lives have been claimed by floods and landslides brought on by a tropical depression that hit the ...

NASA turns research to California drought
NASA scientists have begun deploying satellites and other advanced technology to help California water officials assess the state's record drought and better manage it, officials said Tuesday. The California Department of Water Resources has partnered with NASA to use the space agency's satellite data and other airborne technology to better assess the snowpack, ground water levels and predict ...

Fire risk in Mediterranean Europe mapped using satellite images
Satellite observations are valuable aids to detect and monitor fire activity. A recent study has investigated how satellite images of fire activity, together with information on vegetation cover and fire risk associated with long and short-term atmospheric conditions could be used to help authorities better manage the risk of wildfires in Mediterranean Europe. Wildfires, especially in southern ...

African water atlas launched in French
The UN Environment Programme (UNEP) has published a French version of its 'Africa Water Atlas', a compendium of maps, satellite images and 'before and after' images that reveals the vulnerability of the continent's water resources. It was launched last month during World Water Week (21–28 August), in Sweden, where UNEP said that it would make a major contribution to the state of knowledge ...

Europe`s land use mapped through new field survey tool
The LUCAS viewer, a new mapping tool managed by the European Environment Agency, now allows users to see land-cover information based on satellite images as well as thumbnail-size photographs taken in sampled locations across Europe. Explore Europe's changing landscape. Adding such in situ observations to satellite data leads to a more accurate and detailed presentation of Europe's landscape. ...

Studying glaciers at the top of the world
A string of high-altitude research stations across Asia could shed light on how climate change is affecting one of the world's largest ice masses. Spearheaded by the Institute of Tibetan Plateau Research, part of the Chinese Academy of Sciences, the initiative is building state-of-the-art research facilities across South Asia, including in Nepal, Pakistan and Tajikistan. The move could help ...

New satellite imaging to better forecast locust plagues
Information from satellites is being used in a new way to predict favourable conditions for Desert Locust swarms, as part of an early warning collaboration by scientists from the European Space Agency (ESA) and Desert Locust experts at the UN Food and Agriculture Organization (FAO). The new technology will help to increase the warning time for locust outbreaks by up to two months. Using data ...

Freshwater runoff from Greenland Ice Sheet will more than double by the end of the century
The Greenland Ice Sheet is melting faster than previously calculated according to a recently released scientific paper by University of Alaska Fairbanks researcher Sebastian H. Mernild. The study, published in the journal Hydrological Processes, is based on models using data from the Intergovernmental Panel on Climate Change, as well as satellite images and observations from on the ground in ...

British-US survey team captures dramatic images of Antarctic shelf break-up
British Antarctic Survey, collaborating with the University of Colorado, has captured dramatic satellite and video images of an Antarctic ice shelf that looks set to be the latest to break out from the Antarctic Peninsula. A large part of the Wilkins Ice Shelf on the Antarctic Peninsula is now supported only by a thin strip of ice hanging between two islands. It is another identifiable impact of ...

Explore Europe`s changing landscape
What does Europe use its land for? Where are farmlands, urban areas and forests? How has Europe's land cover changed over a decade? All European information and data relevant to the practice and environmental impact of land use are now brought together on the EEA's new thematic website on land use. In addition to the policy context and the EEA activities in this field, the website also gives ...

Egyptian climate change atlas sparks debate
Claims that climate change will leave 4,000 square kilometres of Egypt under water and ten per cent of the population homeless have led to a dispute within the academic community about the country's environmental future. An 'Atlas of Risks of Climate Change on the Egyptian Coasts and Defensive Policies', launched at a press conference in Cairo last month (3 November), surveyed the threats facing ...

Satellite imagery shows fragile Wilkins Ice Shelf destabilised
Satellite images show that icebergs have begun to calve from the northern front of the Wilkins Ice Shelf – indicating that the huge shelf has become unstable. This follows the collapse three weeks ago of the ice bridge that had previously linked the Antarctic mainland to Charcot Island. The ice bridge, which effectively formed a barrier pinning back the northern ice front of the central Wilkins ...

Satellite Images Display Extreme Mississippi River Flooding from Space
Recent Landsat satellite data captured by the USGS and NASA on May 10 shows the major flooding of the Mississippi River around Memphis, Tenn., and along the state borders of Tennessee, Kentucky, Missouri, and Arkansas as seen from 438 miles above the Earth. The flood crest of 47.87 feet on May 10 is the second highest rise in recent history; the highest being 48.7 feet in 1937. Five counties ...
