GSA is Celebrating Advances in Geoscience —
Our science, our societal impact, and our unique thought processes looking at how far we have come in the last 50 years and predicting future advances.
There are plenty of good reasons to join your colleagues at any GSA Annual Meeting, but this year affords a special opportunity to reflect on how GSA and its members are building upon the Society’s long tradition of achievements and laying the groundwork for future generations of geoscientists.

This year marks the 125th Anniversary for the Geological Society of America!

If you have a  CZO-related presentation at the GSA annual meeting that you would like featured here, please send in the abstract information. 

Special workshop prior to the meeting: Drilling the Depths of the Critical Zone
(Cosponsored by Univ. of Wyoming; Univ. of Arizona; National Science Foundation)
24–25 Oct., 8 a.m.–5 p.m. Hyatt CCC, Centennial Ballroom H

T18. Critical Zone Evolution: Climate and Exhumation | Session 165; 1-5 pm Monday Oct. 28 | CCC Mile High Ballroom 2C
Suzanne P. Anderson, David P. Dethier, Gregory E. Tucker, Robert S. Anderson
The architecture of the critical zone (CZ)—its thickness, character, and three-dimensional shape—is governed by erosion and weathering. We encourage submissions that explore processes, rates, and feedbacks among climate, rock type, and exhumation that drive CZ evolution.

T53. Mountain Groundwater: Recent Advancements in the New Era of Climate Change and Resource Development | Session 389; 1-5 pm Wednesday Oct. 30 | CCC 207
Andrew H. Manning, Jonathan Saul Caine and Lyndsay B. Ball
Mountain hydrologic systems are rapidly evolving in the face of climate warming and competing resource needs. We welcome abstracts from multiple disciplines that provide new perspectives and understanding of mountain groundwater under these mounting pressures.

T161. Hydrochemistry and Biogeochemistry of Tropical Mountainous Rivers & Estuaries | Session 81; 1-5 pm Sunday Oct. 27 | CCC 504
Steven T. Goldsmith, Russell Harmon, Ryan P. Moyer
We encourage contributions that examine the hydrochemistry of tropical mountainous rivers and/or the biogeochemical cycling and fluxes, as well as paleo-records, of material delivered by tropical mountainous rivers and associated estuarine and coastal waters.

T162. Interdisciplinary Studies across the Critical Zone | Session 212; 8 am - 12 pm Tuesday Oct. 29 | CCC 503
JoAnn M. Holloway, Henry Lin, Martin B. Goldhaber, Jean M. Morrison
Interplay between biological, chemical, and physical processes is crucial to the function of the Critical Zone in regulating soil, water, and air quality. This session seeks presentations from soils, ecology, microbiology, hydrology, and biogeochemistry perspectives.

T163. Pedogenic Minerals as Indicators of Ecosystems: Understanding the Critical Zone through Space and Time | Session 320; 8 am - 12 pm Wednesday Oct. 30 | CCC 504
Neil J. Tabor, Craig Rasmussen
This session will emphasize the occurrence and distribution of pedogenic minerals in response to a range of different soil-forming factors and how those minerals in paleosol profiles provide proxies of ancient critical zones and paleoenvironments.
