WSWED1: Characterization and Speciation of Marine Materials using Synchrotron Probes

Wednesday 19 May 2021, 13:00 → 17:10 US/Eastern

Zoom Link: https://bnl.zoomgov.com/j/1610923439?pwd=UzliaDY0dXpHQ2dsUkFnZDJpTmJldz09

This workshop will bring together people who are using synchrotron methods on marine materials with potential new users in the marine science community, to share techniques and to address common challenges.  This will educate and inform new users in this growing area of interest, to help them build on existing experiences and be successful in proposing and collecting synchrotron data on marine materials.

Workshop Organizers:

Sarah Nicholas (NSLS-II)
Rose Jones (University of Minnesota)
Paul Northrup (Stony Brook University)

Workshop Speakers:

Brandy Toner (University of Minnesota)
Alesandra Leri (Manhattan Marymount College)
Colleen Hoffman (University of Washington)
Phoebe Lam (University of California, Santa Cruz)
Ben Twining (Bigelow Laboratory for Marine Sciences)
Wen Hu (NSLS-II)
