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.

DEEPS PhD students Brianna Hoegler and Jared Nirenberg, with the support of hundreds of fellow scientists, have written a letter to the National Science Foundation expressing their concerns regarding the future of scientific ocean drilling research.
