Wind and wave data from ESA's Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race. CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution. Based on the trajectory and speed of the boats, CLS is...

The Arctic is undergoing rapid transformation due to climate change, pollution and human activity. ESA's ERS and Envisat satellites have been providing satellite data of the region for the last 17 years. These long term data sets in combination with ESA's future missions will be key in implementing the newly adopted European Commission policy called 'The European Union and the Arctic Region'. The policy highlights new opportunities in the region such as the opening up of long-sought...

U.S. scientists say they've created a computer program to help predict when icebergs will calve from ice sheets. The models we have do not currently have any way to figure out where the big ice sheets end and where the ice calves off to form icebergs, said Penn State Professor Richard Alley. The problem, he said, is the great variability involved in iceberg calving. One important variable -- the one that accounts for the largest portion of when the iceberg breaks -- is the rate at which ice...

Scientists have developed computer models that are useful in predicting how fast icebergs break off Antarctica and Greenland. Researchers hope the discovery will enable them to predict rising sea levels due to global warming caused by the burning of fossil fuels. "To predict the future of the ice sheet and to understand the past, we have to put the information into a computer," says Richard B. Alley, the Evan Pugh professor of geosciences at Pennsylvania State University. "The models we have...

Federal officials confirm 10 polar bears, an unusually large number, have recently been seen swimming in open Alaskan waters. Arctic ice melts in the Chukchi Sea are the suspected cause of the bears swimming toward either land or more remote icebergs, The New York Times reported Saturday. Such sightings were rare until 2004 but have grown more common as polar bears hunt for seals. "It's not unusual for bears to be swimming," said Susanne Miller, a biologist with the Fish and Wildlife...

Scientists in Britain have discovered a new global warming threat to marine life in Antarctica -- breakaway icebergs that destroy any life in their path. Shallow habitats of species such as giant sea spiders, Antarctic worms, sea urchins and corals face growing risk from icebergs as they tear up the sea floor, The Times of London reported Friday. The findings indicate climate change risks go beyond rising ocean temperatures, the British Antarctic Survey team said. Although near-shore...

The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. The statement was released during a five-day conference held at ESRIN, ESA's Earth Observation Centre in Frascati, Italy, in which operational ice experts from Europe and North America gathered to discuss the state of the polar regions. "In September 2007, the Arctic sea...

WELLINGTON, New Zealand -- An iceberg has been spotted from the New Zealand shore for the first time in 75 years, one of about 100 that have been drifting south of the country. The giant ice chunk was visible Thursday from Dunedin on South Island but has since moved away, driven by winds and ocean currents. The flotilla of icebergs - some as big as houses - were first spotted south of New Zealand early this month. Last year, icebergs were seen in the country's waters for the first time in 56...

CHICAGO (UPI) -- U.S. scientists say a severe storm in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg. The team of scientists -- led by Professors Douglas MacAyeal of the University of Chicago and Emile Okal at Northwestern University -- said the swell was so powerful it destroyed the iceberg near the coast of Antarctica, more than 8,300 miles away. "We are reporting on a unique kind of seismological signal picked up by seismometers...

BERLIN (Reuters) - Scientists monitoring earth movements in Antarctica believe they have found a singing iceberg. Sound waves from the iceberg had a frequency of around 0.5 hertz, too low to be heard by humans, but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up, the scientists said. The German Alfred Wegener institute for polar and marine research publish the results of its study, done in 2002, in Science magazine on Friday. Between July...

Word of the Day
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
