Incorporating Traditional Management Techniques to Combat Effects of Ocean Acidification
via Incorporating Traditional Management Techniques to Combat Effects of Ocean Acidification Denver, Colo., USA: Ocean acidification is a major concern related to climate change, with the oceans currently absorbing around a quarter of the carbon dioxide that is released into the atmosphere. The increased CO 2 that is absorbed by the ocean in turn decreases its pH, making… Continue reading Incorporating Traditional Management Techniques to Combat Effects of Ocean Acidification
Previously Deployed Military Personnel Show Retained Dust in Lungs
via Previously Deployed Military Personnel Show Retained Dust in Lungs Denver, Colo., USA: Military personnel who were deployed in Afghanistan and Iraq may have been exposed to significant amounts of dust and other respiratory hazards, leading to persistent respiratory symptoms and diseases like asthma and bronchiolitis. Researchers from the U.S. Geological Survey (USGS) and National… Continue reading Previously Deployed Military Personnel Show Retained Dust in Lungs
Earliest record of wildfires provide insights to Earth’s past vegetation and oxygen levels
Boulder, Colo.: While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth’s systems without the influence of humans for hundreds of millions of years. “Wildfire has been an integral component in earth-system processes for… Continue reading Earliest record of wildfires provide insights to Earth’s past vegetation and oxygen levels
Yellowstone’s History of Hydrothermal Explosions over the Past 14,000 Years
Boulder, Colo.: While much of public attention on Yellowstone focuses on its potential to produce large supereruptions, the hazards that are much more likely to occur are smaller, violent hydrothermal explosions. Hydrothermal explosions occur when near-boiling water suddenly flashes into steam, releasing large amounts of energy. The energy release fractures the rock downward, often leaving… Continue reading Yellowstone’s History of Hydrothermal Explosions over the Past 14,000 Years
Fossil discovery reveals that trilobites had clasper-like limbs used for mating
via Fossil discovery reveals that trilobites had clasper-like limbs used for mating Boulder, Colo., USA: Thanks to their easily fossilized exoskeleton, trilobites largely dominate the fossil record of early complex animal life. However, trilobite appendages and the anatomy of the underside of their body are typically not well preserved, which makes it difficult to infer… Continue reading Fossil discovery reveals that trilobites had clasper-like limbs used for mating
Rapid glacial advance reconstructed during the time of Norse occupation in Greenland
via Rapid glacial advance reconstructed during the time of Norse occupation in Greenland Boulder, Colo., USA: The Greenland Ice Sheet is the second largest ice body in the world, and it has the potential to contribute significantly to global sea-level rise in a warming global climate. Understanding the long-term record of the Greenland Ice Sheet,… Continue reading Rapid glacial advance reconstructed during the time of Norse occupation in Greenland
Nealtican lava flow field, Popocatépetl volcano: A window to the past and future hazards
via Nealtican lava flow field, Popocatépetl volcano: A window to the past and future hazards Boulder, Colo., USA: The Popocatépetl volcano, located southeast of Mexico City, stands as the second highest peak in Mexico and is considered to be one of the potentially most dangerous volcanoes in the world, given its record of highly explosive… Continue reading Nealtican lava flow field, Popocatépetl volcano: A window to the past and future hazards
Three Former GSA Members Honored with Lunar Crater Names
via GSA TODAY | March-April 2022 By Emily Zawacki, 2021–2022 GSA Science Communication Fellow Previously unnamed impact craters on the south polar region of the moon are being named to honor three former Geological Society of America (GSA) members. These craters were discovered while studying the south pole of the moon in advance of NASA’s… Continue reading Three Former GSA Members Honored with Lunar Crater Names
Discovering sources of Roman silver coinage from the Iberian Peninsula
via Discovering sources of Roman silver coinage from the Iberian Peninsula Boulder, Colo., USA: Despite its prior status as a luxury commodity, silver became widely used for coinage in the Roman world from the 7th century BCE onward and provided a standardized monetary system for ancient Mediterranean civilizations. However, the sources of silver used to… Continue reading Discovering sources of Roman silver coinage from the Iberian Peninsula
