2nd US Ice Core Community Meeting

May 8-10, 2023

Center for Urban Horticulture

University of Washington, Seattle, WA




The second annual US Ice Core Open Science Meeting will be held May 8-10, 2023, at the beautiful Center for Urban Horticulture at the University of Washington in Seattle, WA. Registration for the meeting is now open.

Abstract Submission and Early Registration Deadline are March 15, 2023.

This meeting is intended for anyone interested in ice core science or related fields, including ice-core analysis, ice or subglacial drilling, glacier geophysics that supports or depends on ice core records, paleoclimate, and contemporary climate and ice sheet change.

Goals of the meeting include 1) sharing the latest science, 2) discussing future ice core science projects in both polar regions and in alpine environments, 3) providing career development opportunities, and 4) improving communication about ice-core and related science both within and beyond the scientific community. We hope to attract a diverse group of participants, including those who may not have extensive experience working with ice cores.

While this meeting is primarily oriented at researchers in the US, international colleagues are welcome to attend.

The meeting will begin midday on Monday, May 8, and end in the late afternoon of Wednesday, May 10. There are three additional meetings occurring in conjunction with the US Ice Core Open Science Meeting:

  • Ice Core Early Career Researcher Workshop (ICECReW) on Sunday, May 7 and Monday morning May 8. Applications have closed.
  • COLDEX short course for early career researchers on Thursday May 11 and Friday May 12 at Camp Casey, Whidbey Island, WA. Applications have closed.
  • Ice Core Working Group (including participants from the IDP Science Advisory Board) on Thursday May 11 on the UW campus (ATG210). This meeting is open to all.

To ensure you do not miss announcements, we recommend joining the Hercules Dome mailing list.
