April 20th, 2013High school junior Monro Obenauer won a special award from the Colorado Geological Survey at last month's prestigious Intel International Science and Engineering Fair. Mentored by INSTAAR grad student Stephanie Higgins, Obenauer's research was on eroding islands in Bangladesh.
August 10th, 2010Bob and Suzanne Anderson have just published their textbook Geomorphology: The mechanics and chemistry of landscapes with Cambridge Press. The hefty tome represents a decade of work. Early reviews are glowing.
July 10th, 2010Bob Anderson, Irina Overeem and Cameron Wobus led a research team that won the 2009 partnering award from the National Oceanographic Partnership Program (NOPP).
June 5th, 2010Phil Taylor and Alan Townsend have discovered that global ratios of nitrogen and carbon in the environment are inexorably linked, a finding that may lead to new strategies to help mitigate regional problems ranging from contaminated waterways to human health. Their new study focused on the growing worldwide problem of nitrogen pollution.
December 1st, 2009Researchers have found that the northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by 30 to 45 feet a year because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity. The 12-foot-high bluffs topple into the Beaufort Sea during the summer months, where the coastal seawater melts them in a matter of days, sweeping the silty material out to sea.
September 20th, 2009James Syvitski, Albert Kettner, Irina Overeem, Eric Hutton and Mark Hannon, along with colleagues from six other institutions, have shown that most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk.
February 4th, 2009James Syvitski led the effort to install a new supercomputer at INSTAAR that will vastly extend the ability of scientists across the globe to model and predict many important aspects of Earth's surface processes, from glacial melting and flooding to coastal erosion and tropical ocean storms. The new computer cluster is the heart of the NSF-funded Community Surface Dynamics Modeling System (CSDMS).
September 26th, 2008Andy Revkin has posted a time-lapse video of Alaska’s rapidly eroding Arctic coast by INSTAAR and USGS researchers on his New York Times Dot Earth Blog.
May 15th, 2008Researchers used a numerical model of ice-sheet behavior to discover that a single feedback loop explains a long-standing geomorphic enigma: why do fjords often extend to depths well below sea level and cut deeply into continental edges?
November 26th, 2007A University of Colorado team led by INSTAAR Suzanne Anderson was awarded funding by the National Science Foundation for a five-year project to establish a Critical Zone Observatory (CZO) in the Boulder Creek Watershed.
May 18th, 2007Syvitski will be the executive director of a new NSF initiative, the Community Surface Dynamic Modeling System (CSDMS), which will study how landscapes and seascapes change over time, and how materials like water, sediments and nutrients are transported from one place to another. These studies will allow better predictions about areas at risk to phenomena like deforestation, forest fires, land-use changes and the impacts of climate change.
February 16th, 2006Robert S. Anderson was elected a fellow of the American Geophysical Union for “fundamental and pioneering contributions in quantitative geomorphology, geochronology, hydrology and glaciology." Fellowship is bestowed on only 0.1% of the total AGU membership of about 35,000 in any given year and recognizes scientists who have attained acknowledged eminence in the geophysical sciences.
November 20th, 2005Gifford Miller received the Easterbrook Distinguished Scientist Award at the Geological Society of America's (GSA) 2005 annual meeting.
July 15th, 2002At least three reservoirs likely will be contaminated by erosion in areas burned by this season's record wildfires, according to INSTAAR research assistant and graduate student John Gartner.
November 7th, 2001James Syvitski, William Manley, Mark Dyurgerov, and Scott Peckham are participating in an extensive research project "Alaska North Slope Climate Impact Assessment."

In The News
February 22nd, 2017Thanks to a $6.8 million renewal grant to CU Boulder’s Institute of Arctic and Alpine Research (INSTAAR) from the National Science Foundation (NSF), research at the Niwot Ridge study area – one of NSF’s 25 Long-Term Ecological Research (LTER) sites in North America – will continue for another six years.
November 17th, 2016Robert S. Anderson, whose research interests include the mechanics of landscape evolution, modeling of landform development and glaciology, will deliver his talk, titled “Mountains, Gold and Glaciers,” about how glaciers carved the mountains in the region and produced sediment and gold to the rivers below.
April 26th, 2016“If one wants to see evidence of a higher sea, downtown Miami is a good place,” said Daniel Muhs, a United States Geological Survey geologist who has studied limestone from the Eemian Interglacial Period laid down under a shallow sea that is now an outcropping in downtown Miami. Back then, the sea was 20 to 30 feet higher than it is today. For that reason, what happened during the Eemian has drawn intense interest from geologists and climate scientists who have tried to resolve the period’s central mystery: How could temperatures so similar to today’s cause the sea to rise so high? And what does it mean for our own future in a warming climate caused by the burning of fossil fuels?
April 15th, 2016Around a quarter of the land in the Northern hemisphere remains frozen year round, making up an important part of the cryosphere known as permafrost. Permafrost areas store a huge amount of carbon, around twice as much as currently exists in the atmosphere. As the global climate warms these frozen areas of ground begin to thaw, and the trapped carbon is released into the atmosphere in the form of CO2 and methane – both greenhouse gases. A new study by Jafarov and Schaefer, published last month in The Cryosphere, has improved the way frozen organic carbon is represented and simulated in the computer models. This is a step closer to better understanding permafrost carbon release and the factors that effect it.
February 23rd, 2016James Syvitski said more than two-thirds of the the world’s 33 major deltas are sinking and the vast majority of those have experienced flooding in recent years, primarily a result of human activity. Some 500 million people live on river deltas around the world, a number that continues to climb as the population increases. From the Yellow River in China to the Mississippi River in Louisiana, researchers are racing to better understand and mitigate the degradation of some of the world’s most important river deltas.
February 6th, 2016In July 2011, Arnaud Temme and three friends were climbing the Rottalgrat, a tough route on the west side of the Jungfrau in Switzerland’s Bernese Oberland, when rocks began to rain down from above. Temme and his team eventually completed the route unharmed. But the climbers noticed that their guidebook, which was a decade old, described the route as relatively safe with only minor rockfall danger. “But the more recent guidebook, which we didn’t have, said to stay away from this route because of very high rockfall danger,” Temme says. The disparity struck Temme, and served as the impetus for Temme’s three-year study into the effects of climate change on alpine climbing danger, the results of which were recently published in Geografiska Annaler.
