Abstract In regions formerly covered by continental ice, till sheets 05 contain distinctive clastic particles derived from local bedrock sources such as ore bodies. Such particles, especially in thicker tills, 05 be distributed in three-dimensional dispersal trains or plumes. Developments in our understanding of glacial erosion, entrainment, and deposition over the past two or three […]

University of Maine’s Jasmine Saros and a team of graduate students and post-doctorate students are in Greenland this summer investigating diatom assemblages for clues on how climate change 05 impact Arctic lakes.  Diatoms, some of the smallest organisms in the Arctic, 05 be the biggest indicators of climate-related changes in the region’s lake ecosystems. These […]

Abstract Explosive volcanism resulting in stratospheric injection of sulfate aerosol is a major driver of regional to global climatic variability on interannual and longer timescales. However, much of our knowledge of the climatic impact of volcanism derives from the limited number of eruptions that have occurred in the modern period during which meteorological instrumental records […]

Two entries from University of Maine graduate students have been submitted into the National Science Foundation’s Integrative Graduate Education and Research Traineeship (IGERT) program’s 2013 Video and Poster Competition. Maureen Correll and Bjorn Grigholm, graduate students in the Adaptation to Abrupt Climate Change IGERT program at UMaine, submitted a video and poster titled “Abrupt Climate […]

Announcing the 6th Annual Climate Change Science Day at the University of Maine on May 2, 2013. This open house will include tours and demonstrations aimed at high school students and will feature visits to the following laboratories: * Ice Core Glaciochemistry Laboratories — Visit the labs that measure the chemistry of ice cores used […]

Professor George Denton of the Climate Change Institute, and co-authors Philip Conkling, Richard Alley and Wallace Broecker are recipients of the Phi Beta Kappa Book Award in Science for “The Fate of Greenland: Lessons from Abrupt Climate Change,” published in 2011. The award recognizes outstanding contributions to science literature. As noted in Phi Beta Kappa […]

The Penobscot Bay Pilot wrote an article about the upcoming trip to Alaska by University of Maine climate change researchers to collect an ice core record of Arctic climate change over the past 1,000 years. Karl Kreutz, professor in UMaine’s Climate Change Institute and School of Earth and Climate Sciences; UMaine graduate student Seth Campbell; […]

Catherine West was a junior history major at Bryn Mawr when she jumped at the chance to be a field school student during a 1998 dig at a prehistoric Aleut site on Unalaska Island. As part of that summer adventure, she met welcoming locals, hiked lush green mountains, saw whales breach in the Bering Sea, […]

This study provides a baseline from which changes in the chemistry of the atmosphere over Antarctica can be monitored under expected warming scenarios and continued intensification of industrial activities in the Southern Hemisphere. It is the first study to measure more than 25 chemical constituents in the surface snow and firn across extensive regions of […]
