Winnemucca GSN February Meeting

The Martin, 94 W. Railroad St.
Food and Drinks at 6 pm
Talk at 7 pm
Speaker: Janine Andrys, Boise State University Postdoctoral Research Fellow
Talk: “Submarine Lavas of the Galápagos”
FOOD AND BEER SPONSOR: NATIONAL EWP, Vanguards of Drilling
Abstract: The Galápagos Archipelago sits atop a submarine platform that extends ~3000 meters down to the seafloor. This Platform makes up the volume majority of the Galápagos and is different from the structure of other well studied ocean islands, like Hawaii, which typically display a continuous island chain with steep submarine banks. While extensive work has been conducted characterizing the subaerial lavas of the Galápagos, little has been done on the submarine lavas that make up the Platform. In 2023, we conducted two research expeditions to survey and sample the Galápagos Platform, utilizing high-resolution shipboard multibeam bathymetry, human-occupied vehicle Alvin, and remotely operated vehicle SuBastian to conduct our work. In this talk, I will present the results of these research expeditions, highlighting our visual observations of the lava flows and accompanying biological habitats, in addition to new geochemical results of the Platform lavas, which we use to constrain an constructional model of the Galápagos that incorporates both the subaerial and submarine portions of the archipelago.
Bio: Janine Andrys is an igneous petrologist and high-temperature geochemist that specializes in the crystallization of basaltic magmas and identifying the geochemical fingerprints of processes related to recycling in the mantle, mantle heterogeneity, and mantle evolution. Her work employs high-precision geochemical analysis of volcanic rocks and glasses, as well as bathymetric and field observations of the seafloor. Janine received her B.S. in Earth Sciences from the University of Minnesota and her PhD in Marine Geology from the University of Rhode Island Graduate School of Oceanography. Janine is a current Postdoctoral Research Fellow at Boise State University.
