DEEPS PhD student Alejandra López contributes to two new briefs revealing widespread nutrient pollution, dangerously low oxygen levels in the lake, and frequent episodes of hydrogen sulfide emissions that exceed California’s health standards—conditions occurring among residents in areas that rank among the most burdened by pollution in the state. López noted, “Families live with chronic exposure to pollutants that would never be tolerated elsewhere. We call for enforceable standards and local-focused solutions that put residents at the center of restoration.”

In a new study published in Icarus, a team of researchers led by DEEPS graduate student Thomas Williams and Professors Stephen Parman and Alberto Saal have used modern analysis techniques to closely examine the microscopic mineral deposits on the outside of lunar beads from the Apollo mission. The team's findings suggest a change in eruption style over the course of a pyroclastic volcanic eruption in the Taurus-Littrow Valley.

Ice sheet melt has been shown to increase volcanic activity in subglacial volcanoes elsewhere on the globe. DEEPS PhD candidate Allie Coonin and her team ran 4,000 computer simulations to study how ice sheet loss affects Antarctica’s buried volcanoes, and they found that gradual melt could increase the number and size of subglacial eruptions.

Fishermen and scientists report that tarpon, a large warm-water trophy fish, have been migrating north. In June, Thomas Czernik, a DEEPS graduate student was fishing for striped bass at night off Aquidneck Island in Rhode Island. “I feel lucky,” Czernik says. “It’s a memory I’ll have forever. I’m thankful.”

This summer, DEEPS Assistant Professor Emily H. G. Cooperdock, graduate student Anahi Carrera, and Columbia University Professor Steven L. Goldstein visited the island of Unalaska to collect samples that will help interpret data from a 2015 NSF GeoPRISMS campaign, as well as pave the way for future research.

DEEPS PhD candidate César Bucheli recently published a new paper in Contributions to Mineralogy and Petrology, titled “What can we learn from geothermobarometry at the dacitic Doña Juana Volcanic Complex (Colombia)? Implications for understanding Pleistocene crystal mushes and pre-eruptive storage conditions in the Northern Andes.” Bucheli and co-authors reconstructed the geochemical behavior of Pleistocene melts feeding eruptions of the Doña Juana Volcanic Complex (SW Colombia, Northern Andes) and found evidence to suggest the existence of one of the first examples of long-lived trans-crustal magma systems in the country.
