Critical Zone Observatories U.S. National Program
As the dog days of summer begin to wind down, I hope those with intensive field sampling are finishing strong. In the same vein, this is the last year of the current CZO program, and we want to "finish strong" while also looking forward to the future iteration of the CZO program. We had a very exciting Arlington Meeting for CZ Science in June, and by all reports, made a positive impression with staff from NSF and other federal agencies. We (the community) expect a program announcement from NSF about CZOs sometime this fall, but at this moment we do not have any details about when they will release a solicitation.

There is a lot of exciting CZ science in the works and many of us are getting ready for fall conferences to showcase the results of past field seasons. For those attending the AGU Fall Meeting in New Orleans this year, check our AGU event page for information on CZ-related sessions and events during the meeting. I look forward to seeing you there!

Hydrologic cycling across Critical Zone Observatories
Current Research Highlight

Adam Wlostowski began a CZO-funded postdoctoral fellowship at the Institute of Arctic and Alpine Research (INSTAAR; University of Colorado, Boulder) studying cross-CZO Critical Zone science. He is co-advised by Noah Molotch (Boulder Creek CZO & Southern Sierra CZO) and Ciaran Harman (Johns Hopkins University). His research is focusing on two questions:
1) How does critical zone structure influence hydrologic processes and functions?
2) Do hydrologic processes and critical zone structures co-evolve?

To help answer these questions, Wlostowski is undertaking an ambitious but needed project of coalescing and analyzing hydrologic data across the CZO Network. This project will include visiting each CZO to document the perceptual models of hydrologic function. His research seeks to leverage the CZO Network to reconcile the results of broad, top-down, hydrologic synthesis analyses against a legacy of process-based hydrologic research at each CZO (perceptual models). Cross-CZO hydrologic synthesis research is necessary to distill and articulate the coupled relationship between hydrologic function and critical zone structure. 
Critical Zone science provides a remarkable conceptual umbrella for studying hydrology. Lodged between bedrock and boundary layer, I see the critical zone as a complex filter through which water is transmitted across a disparity of time scales (minutes to millennia)...

Jobs & Opportunities

Call for papers: Critical Zone Export to Streams as Indicator for CZ Structure and Function
Frontiers in Earth Science, section Biogeoscience

Abstract submission deadline: October 6 

The goal of this Research Topic (special issue) is to explore linkages between biotic and abiotic weathering, soil biogeochemical processes, chemical and physical denudation and hydrology within the CZ. The topic editors invite contributions that explore streams as an integrated window into CZ processes at different scales and from various perspectives. They welcome field observations and /or models linked to biogeochemical, hydrological, ecological, biological and pedological processes in traditional and novel ways that relate results on stream water dynamics back to CZ function in a time of accelerated global change.

Postdoctoral Position: Long-Term Earth System Change
Kansas State University

Application review begins: August 21

A postdoctoral position is available at Kansas State University focused on the temporal aspects of interactions among biogeochemistry, paleoecology, and global change. The postdoc will perform original research on topics in paleoenvironmental change, especially related to long-term biogeochemistry and disturbance, in collaboration with supervisor Kendra McLauchlan. The primary responsibilities associated with this position are: (1) to assist with coordination of a diverse and broad network of researchers in the U.S. and elsewhere, and (2) to conduct independent research on the biogeochemical consequences of ecosystem change at decadal to multi-millennial timescales.

CUAHSI Instrumentation Discovery Travel Grant program

Proposal submission deadline: September 30

CUAHSI is now accepting proposals for the Instrumentation Discovery Travel Grant program (IDTG). The IDTG offers travel grants of up to $1,000 to permit academic scientists to visit colleagues to efficiently and economically learn new instrumentation. IDTG’s enable scientists to learn new instrumentation techniques in the hydrologic sciences by visiting other research sites and meeting with the respective site’s Principal Investigators to learn the details of hydrologic instrument installation, operation, maintenance, and data processing. Questions can be directed to Jon Pollak

Assistant Professor: Weathering and Soil Development
University of Lausanne

Application deadline: October 15

The Faculty of Geosciences and Environment at the University of Lausanne seeks to appoint an Assistant Professor (tenure track) in Weathering and Soil Development at the Institute of Earth Surface Dynamics (IDYST). The position will focus on processes in the critical zone that link the impact of weathering to the Earth’s climate and to the evolution of landscape and biomass. Research approaches that integrate different temporal and spatial scales to identify mechanisms of soil development and the quantification of rates and fluxes involved in weathering processes are highly encouraged. We look for a candidate who would complement current expertise in IDYST (Aqueous and Isotope Biogeochemistry, Biogeosciences, Geo- and Thermochronology, Geomorphology) and who has the potential to establish collaborations with the Institute of Earth Sciences and the Institute of Geography and Sustainability.
