Ancient Landscape Exists Beneath Greenland’s IceSome of the landscape underlying the massive Greenland ice sheet may have been undisturbed for 2.7 million years, ever since the island became completely ice-covered, according to researchers funded by the National Science Foundation (NSF).Basing their discovery on an analysis of the chemical composition of silts recovered from the bottom of an ice core more than 3,000 meters long, the researchers argue that the find suggests “pre-glacial landscapes can remain preserved for long periods under continental ice sheets.”Read more: http://www.laboratoryequipment.com/news/2014/04/ancient-landscape-exists-beneath-greenlands-ice

  3. 'Dressed' Laser May Induce Rain, LightningThe adage, “Everyone complains about the weather but nobody does anything about it,” may one day be obsolete if researchers at the Univ. of Central Florida’s College of Optics & Photonics and the Univ. of Arizona further develop a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning.The solution? Surround the beam with a second beam to act as an energy reservoir, sustaining the central beam to greater distances than previously possible. The secondary “dress” beam refuels and helps prevent the dissipation of the high-intensity primary beam, which on its own would break down quickly.Read more: http://www.laboratoryequipment.com/news/2014/04/dressed-laser-may-induce-rain-lightning

  7. Forensic Genomics Solves Case of the Red Abalone Die-offIn August 2011, thousands of dead red abalone washed up on the beaches of Sonoma County in Northern California. At the time, the cause was unknown. Now, scientists, including a biologist from UC Davis, have learned that a harmful algal bloom was to blame: the causative agent Yessotoxin.While discovery of the cause itself is noteworthy, the method by which it was determined could have a profound effect on how wildlife mortality events are investigated in the future. Described in a study published in Nature Communications, the researchers call this new approach “forensic genomics.” It involves a combination of field surveys, toxin testing and genomic scans.Read more: http://www.laboratoryequipment.com/news/2014/04/forensic-genomics-solves-case-red-abalone-die

Puget Sound’s Waters Come from Deep CanyonThe headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.Univ. of Washington oceanographers made the first detailed measurements at the headwater’s source, a submarine canyon offshore from the strait that separates the U.S. and Canada. Observations show water surging up through the canyon and mixing at surprisingly high rates, according to a paper published in Geophysical Research Letters.Read more: http://www.laboratoryequipment.com/news/2014/04/puget-sound%E2%80%99s-waters-come-deep-canyon

  11. Nutrient-rich Forests Store More CarbonThe ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers, including the International Institute for Applied Systems Analysis.The study showed that forests growing in fertile soils, with ample nutrients, are able to sequester about 30 percent of the carbon that they take up during photosynthesis. In contrast, forests growing in nutrient-poor soils may retain only 6 percent of that carbon. The rest is returned to the atmosphere as respiration.Read more: http://www.laboratoryequipment.com/news/2014/04/nutrient-rich-forests-store-more-carbon

Statistics Rule out Natural-warming HypothesisAn analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth’s climate, according to a new study by McGill Univ. physics professor Shaun Lovejoy.The study, published in Climate Dynamics, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels. Rather than using complex computer models to estimate the effects of greenhouse-gas emissions, Lovejoy examines historical data to assess the competing hypothesis: that warming over the past century is due to natural long-term variations in temperature.Read more: http://www.laboratoryequipment.com/news/2014/04/statistics-rule-out-natural-warming-hypothesis

Climate Change Slowdown Linked to Sea Surface TempThe recent slowdown in the warming rate of the Northern Hemisphere may be a result of internal variability of the Atlantic Multidecadal Oscillation — a natural phenomenon related to sea surface temperatures, according to Penn State researchers."Some researchers have in the past attributed a portion of Northern Hemispheric warming to a warm phase of the AMO," says Michael Mann, Distinguished Professor of Meteorology. "The true AMO signal, instead, appears likely to have been in a cooling phase in recent decades, offsetting some of the anthropogenic warming temporarily."Read more: http://www.laboratoryequipment.com/news/2014/04/climate-change-slow-down-linked-sea-surface-temp
