Are you working with #OpenData to advance #freshwater #biogeochemistry? Consider submitting an abstract to share your science in our special session at #2026SFS!

Organized by Ashif H Abir, Wil Wollheim, me, & Kelly Aho @kellyaho.bsky.social. Abstracts due 16 Jan 2026. www.sfsannualmeeting.org 💧🌎🧪
Abstracts due: 16 January 2026 Special Session: Advances in freshwater biogeochemistry using open data across networks of sites Conveners: Ashif Hasan Abir (UNH), Wil Wollheim (UNH), Erin Hotchkiss (VT), & Kelly Aho (BU) With the increasing amount of data from research networks, expanding analytical capabilities and open science policies, there is a paradigm shift from single-site to macro-scale analyses incorporating many ecosystems to tackle knowledge gaps in freshwater biogeochemistry at regional to global scales. We welcome submissions that leverage publicly available data (continuous sensor measurements, field sampling or combination of both) collected across different spatial and temporal scales from multiple sites to advance freshwater biogeochemistry. We are particularly interested in studies utilizing established sensor and measurement networks such as the National Ecological Observatory Network (NEON), Long-term Ecological Research (LTER) networks, Global Lake Ecological Observatory Network (GLEON), and Critical Zone Observatories (CZO) for cross-scale studies. We welcome studies adopting interdisciplinary approaches that use standardized observations, coupled terrestrial and water measurements, high frequency sampling, process-based and/or machine learning models, or any combination of these approaches. Cross-scale studies addressing biogeochemical processes at the interface of terrestrial and aquatic systems such as riparian corridors, hyporheic zones, and different freshwater ecosystems are also encouraged. Throughout this session, we hope to stimulate innovative ideas, approaches and discussions to push our knowledge in freshwater biogeochemistry. To learn more, visit: www.sfsannualmeeting.org

There’s a lot of terminology out there when discussing water quality. This new UF/IFAS publication explains “concentrations” and “loads,” what they are, and why we should care: edis.ifas.ufl.edu/publication/...
SL532/SS747: Water Quality Notes: What are concentrations and loads, and why do they matter?
Water quality is a broad term used to describe a range of physical, chemical, and/or biological characteristics of water. Many different factors contribute to water quality. The decision of whether th...

`genzplyr` is an alternative syntax for `dplyr` that replaces boring old function names with GenZ slang. Your data wrangling is about to hit different.

New post: All The Things I Was Never Trained To Do. Which turns out to be a sneakily disguised meditation on what university education is for, and thus what university is, and what it isn't - despite the persistence of idiots who don't understand that!

I’m reminded just about every day that the disconnect between my education, and the career I built from it, is enormous. Or at least, it seems so. I had a pretty unremarkable educational sequence f…

We measured #VOC & #CO2 fluxes from 3 ponds in a peatland forest using floating chambers. Understanding of freshwater ecosystems as VOC sources is poor, so this work led by Y. Qin, published in #ASLO_LO provides important new data.

Multiple ecology faculty positions at @notredame.bsky.social. Apply at apply.interfolio.com/171650. (1/2). 🌎🌐🧪
Multiple Early Career Faculty Positions in Ecology The Department of Biological Sciences at the University of Notre Dame invites applications for multiple, tenure-track assistant professor positions that will enhance existing institutional excellence in ecology. We are searching broadly for creative and collaborative individuals (1) working at any spatial scale, from local to global, in any system, (2) studying any level of biological organization, from genes to ecosystems, and (3) using any mode of inference, from empirical to theoretical. Applicants should demonstrate research excellence that crosses traditional disciplinary boundaries; ongoing growth in the department will emphasize new hires that use quantitative and/or integrative approaches to study ecological processes. Postdoctoral experience is desirable in applicants. Successful candidates will engage with and benefit from UNDERC, Notre Dame’s 8000-acre environmental field station and home to NEON’s Great Lakes domain, superb on-campus chemical and genomic analytical facilities, an experimental research facility located close to campus, cross-disciplinary interactions through multiple centers and institutes including the Environmental Change Initiative, and a unique Interdisciplinary Graduate Training Program in Environment and Society. New faculty will benefit from Notre Dame’s recent campus-wide Strategic Framework that included the Just Transformations to Sustainability Initiative. Modern research facilities exist in a new environmental research building, which opened in 2025.
