In a new study in AGU Advances, Matthew Winnick describes how runoff laden with nitrogen from fertilizer is leading to increased nitrous oxide emissions in river systems. Read more in the UMass news release.
In a pair of new papers, Michael Rawlins and colleagues describe new numerical model simulations of dissolved organic carbon (DOC) loaded to rivers throughout the western Arctic and how flows of water and DOC are increasing in northwest Alaska. Read more in the UMass news release and the Journal of Geophysical Research-Biogeosciences and Environmental Research Letters journal articles.
CSRC Director Raymond Bradley will lead a team of researchers to Peary Land, Greenland’s northernmost region to document past changes in the climate and environment of the area. This project is supported by a $2.5 million grant from the National Science Foundation. Read more here.
Ph.D. candidate Ruthie Halberstadt has been awarded a highly competitive NSF Post Doctoral Research Fellowship: “High-resolution Nested Antarctic Ice Sheet Modeling to Reconcile Marine and Terrestrial Geologic Data”. Her research project includes ongoing collaborations with professors Rob DeConto, her advisor, and Greg Balco at UC Berkeley.
In a new paper, published today in Nature, Rob DeConto and colleagues describe how warming in excess of 2 C would drastically accelerate the pace of sea-level rise by 2100. The team used a physics-based model of the ice sheet to test Paris Agreement target temperature thresholds. Read more in the UMass news release and the open access journal paper.
In a new study published in the journal Earth and Planetary Science Letters, CSRC Ph.D candidate Anna Ruth Halberstadt and an international team used numerical models and geologic datasets to reconstruct Antarctic climate during the the mid-Miocene. Read more in the UMass press release and journal article.
Research conducted by UMass Amherst Geosciences graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. Read the UMass news release and see the journal article for more information.
A study published today in the Proceedings of the National Academy of Sciences by Francois Lapointe, Raymond Bradley and colleagues documents how Atlantic sea-surface temperatures in the recent decade are warmest as compared to their estimates spanning the past 3,000 years.

Rob DeConto and teams from Columbia, Penn State and the University at Buffalo will receive $3 million in research funds and $4 million for field operations to drill through the Greenland Ice Sheet and into the bedrock below, where they will be able to evaluate how long it has been since the last ice sheet retreated from the continent.
