redOrbit Staff & Wire Reports - Your Universe Online Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution. In research appearing in Monday’s edition of the Nature journal Scientific Reports, Joe McConnell of Nevada's Desert Research Institute (DRI) and his colleagues explain how data from 16 ice cores collected...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well. Early in its existence the Earth was more fluid, with materials all mixing together in a super-heated mix. It took millions of years for differentiation and cooling to achieve the layered Earth we live on today. So traditional geological dating gives us more of a lower bound for the age of the Earth, while...

Greenland ice sheet
2014-05-20 05:10:03

April Flowers for redOrbit.com - Your Universe Online In 1889 and 2012, there was large-scale melting of the Greenland ice sheet. Scientists have assumed these events were driven by warming alone, but a new study from the Thayer School of Engineering at Dartmouth College and the Desert Research Institute reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events. The findings, published in the Proceedings of the National...

Tree Rings Reveal A History Of Drought In Utah
2014-05-02 05:21:34

Brett Smith for redOrbit.com - Your Universe Online New research on tree rings in Utah has revealed that some droughts of the past 576 years were much more severe than anything seen since the start of the 20th century. The study team said tree rings provide a much longer historical record than climate and stream flow logs, which only go back about 100 years. According to the team’s report in the Journal of the American Water Resources Association, the most severe drought of this...

April Flowers for redOrbit.com - Your Universe Online Climatologists use deep-drilled ice core samples in order to understand the climate changes our planet has endured during and between the Ice Ages. A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice. Scientists will be able to use the new dating technique to identify ice that is much older,...

Ancient Landscape Found Beneath Greenland Ice Sheet
2014-04-18 11:47:38

[ Watch The Video: Ancient Soil Found Under Greenland Ice Sheet ] By Joshua E. Brown, University of Vermont Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything—vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. "We found organic soil that has been frozen to the bottom of the...

Mars Rock Dating Analysis
2013-12-13 10:15:24

Brett Smith for redOrbit.com - Your Universe Online While scientists have analyzed the age of rock samples from other planetary bodies before, the work has always been performed on Earth. Now, an international team of scientists has announced the first-ever geological analysis of a rock sample performed on another celestial body – Mars. According to a report in the journal Science Express, the on-planet analysis could lead to a greater understanding of Mars’ geologic history and the...

Long Unchanged Alpine Glacier Is Now Melting At Unprecedented Rate
2013-12-12 06:35:56

April Flowers for redOrbit.com - Your Universe Online An international team of glaciologists, led by Ohio State University, has discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate. The discovery, described at the annual autumn meeting of the American Geophysical Union this past week, was made less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman. A single, dried-out leaf from a larch tree...

Moraine Research May Alter Thinking On Climate’s Effect On Glaciers
2013-11-20 07:58:56

redOrbit Staff & Wire Reports - Your Universe Online A Dartmouth College-led study published in the latest edition of the journal Quaternary Geochronology describes a newly discovered, more accurate method to date the soil and rock debris left behind by high altitude tropical glaciers. The research could alter pre-existing interpretations of how climate change affected equatorial ice masses, the study authors explained in a statement Tuesday. Currently, scientists use a variety of...

Tenontosaurus
2013-01-29 09:53:30

Image Caption: Head of Tenontosaurus, Institut de paléontologie humaine, Paris, France. Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...

Sharpirhynchia sharpi
2014-01-12 00:00:00

Sharpirhynchia sharpi is a species of extinct brachiopod named after fossil collector Samuel Sharp (1814-1882). This species lived during the Lower Bathonian of the Middle Jurassic Period. It is found only in the United Kingdom, and numerous specimens have been taken from several sites, the first from Limekiln Quarry in Northampton, England. S. sharpi is roughly a half-inch long, with a slender beak and 21 to 31 ribs fanning out from the hinge. This lampshell brachiopod lived life as a...

Sauroposeidon, meaning “earthquake god lizard,” is a genus of sauropods dinosaur from the Aptian and Albian ages of the Early Cretaceous Period (110 million years ago). It was discovered in the southeast region of Atoka County, Oklahoma, not far from the border of Texas, in a claystone outcrop. The fossils were initially misidentified as pieces of petrified wood when they were found in 1994. A more detailed analysis in 1999 revealed they were truly dinosaurian bones. They were formally...

Qiaowanlong is a genus of sauropod dinosaur from the Albian stage of the Early Cretaceous Period (100 million years ago). It was discovered in the Yujinzi Basin of Gansu, China in 2007. It came from the geological formation called the Xinminpu Group. Qiaowanlong is known from articulated cervical (neck) vertebrae and a right pelvic girdle, as well as several unidentified bone fragments. It was the first brachiosaurid to have been found from China. Qiaowanlong is estimated to have been...

Qantassaurus is a genus of ornithopod dinosaur from the late Aptian to early Albian age of the Early Cretaceous Period (115 million years ago). It lived in Australia when the continent was still south of the Antarctic Circle, and was still part of the supercontinent Gondwana. Qantassaurus was discovered in 1996 during the third annual field season of the Dinosaur Dreaming Project, a dig jointly run by Monash University and Museum Victoria. It was found in the intertidal site known as Flat...
