    A team of researchers led by UA HAS Professor Xubin Zeng has mapped exactly where in the Western U.S. snow mass has declined from 1982 to 2016. The team mapped the changes in snow mass onto a grid of squares 2.5-miles on a side over the entire contiguous U.S. "A person could practically find the trend for their neighborhood," said first author Zeng. "Grid size for previous studies was about 40 miles on a side. This is the first time anyone has assessed the trend at the 2.5-mile by 2.5-mile pixel level over the 35-year period (1982-2016)." Researchers found that in some areas of the Western U.S... Read More

    Wednesday, December 12, 2018
    The U.S. groundwater supply--the primary source of domestic water for about half the U.S. population--is smaller than orginally thought, according to a new research study that includes UA HAS faculty member, Jennifer McIntosh. McIntosh recently spoke with Arizona Public Media's Arizona 360 host and producer, Lorraine Rivera, about nationwide groundwater supplies falling short of previous estimates. She explained that recent findings show the availability of fresh groundwater resources is about half of what was estimated in earlier studies and that drilling deeper wells may not be a good long-t...

    Congratulations to Antonio Meira, HAS doctoral student, who was recently elected to the American Geophysical Union's Student-Early Career Leadership Council! Antonio will begin his membership on the Student Council in January 2019. The AGU created this council of students and early career scientists to represent a large percentage of the AGU membership with the knowledge that they would bring a forward-looking perspective to the Council and to the AGU. These representatives serve as advocates to their peers from the organization and to the organization from their peers. The Council's three dis... Read More
