A v. warm welcome to Dr. Penny Wieser starting a postdoc at CEOAS - Oregon State, collaborating with myself & Dr. Christy Till (she/her) on understanding the reasons for variations in volcanic style, output & composition in the Cascade arc. Thanks to GeoPRISMS and U.S. National Science Foundation Geosciences for funding too!

A small group of volcanic islands in Alaska's Aleutian chain could actually be part of a single, previously unrecognized giant volcano in the same category as Yellowstone, according to research that will be presented at #AGU20 next week: carnegiescience.edu/news/alaskas-i…

Good morning #AGU20. Join us today as we cover 20 years of GeoPRISMS and MARGINS science. Let's start with our poster session T001 - chat with presenters all day & Poster walk 11am Eastern agu.confex.com/agu/fm20/meeti…

Thanks to all who joined us to the T001 GeoPRISMS MARGINS #AGU20 poster walk. Next -> T006 & T007 oral sessions. Live starts at 10pm Eastern. See you all! agu.confex.com/agu/fm20/meeti…

What do #rifts and #subductionzones have in common? Sure, rifters just want to drift apart, and subducters beat each other up all the time! I’ll be highlighting some unifying themes in the GeoPRISMS session tonight starting at 20:30 PST #AGU20 #GeoPRISMS agu.confex.com/agu/fm20/meeti…

10 years ago at 2:46 pm JST on 3/11 (or 9:46 pm 3/10 in the PNW), the Japan Trench megathrust slipped 60-80 meters in one go. The movement launched a tsunami that was among the largest ever seen with water run-up to 38 meters in places (124 feet: an 11 story building). (1/n)

Earth’s rocky, pressurized interior contains vast stores of fluids rich in #carbon and dissolved gases, constituting a veritable ocean in the rock below our feet. By James Muirhead (University of Auckland | Waipapa Taumata Rau) Donna Shillington (@NAUResearch) & more eos.org/science-update…

there's not enough capital letters to show our excitement! IT IS OUT and we LOVE this AGU's Eos special issue celebrating 20 years of science accomplishments made through the GeoPRISMS and MARGINS programs by our AMAZING community...YOU! U.S. National Science Foundation #nsffunded

The eastern edge of North America, stretching from Florida to Nova Scotia, offers glimpses into the conditions leading to Pangea’s demise. By Lindsay Lowe Worthington Brandon Shuck @SeismoAnne Zach Eilon & Colton Lynner eos.org/science-update…

As the decade-long #NSFfunded program, GeoPRISMS, comes to an end this spring, AGU's Eos’s April issue features just a few of its accomplishments. Read on ⬇️

If you like geodynamic processes at rifting and subducting margins, have we got an issue for you. In April, GeoPRISMS scientists look back at what the decade-long program revealed. eos.org/agu-news/cross…

A decade-long research collaboration has revealed that the split between Africa and North America roughly 200 million years ago was more drawn out than previously thought. eos.org/science-update…

Expeditions run through GeoPRISMS, from marine seismic data acquisitions to onshore field campaigns, provided opportunities for early-career scientists to gain research experience in interdisciplinary science. eos.org/opinions/geopr…
