Can different redox reactions occur simultaneously? Yes!.... and part of the explanation may be variability in natural OM chemistry and associated thermodynamic controls. Read our new paper at authors.elsevier.com/c/1imZR… (free access for 50 days). #PNNLRCSFA @PNNLab @hyunseobsong
Arrived in SF yesterday for #AGU23! Excited for a workshop on Team Science this morning, then my poster presentation Monday AM. See pnnl.gov/events/agu23 for some highlighted presentations by @PNNLab scientists.

#WatershedWednesday - Preprint - unifying microbial processes governing river biogeochemistry are hindered by a lack of genome-resolved functional insights and sampling across multiple rivers.

#NewPublication! - #alert "time series in ecosystem metabolism are well characterized in small and medium rivers, patterns in the world's largest rivers are almost unknown" #WatershedWednesday bit.ly/watershed6

#WatershedWednesday - The @WHONDRS consortium carried out a multi-continent river corridor study to evaluate interactions between metabolomes, microbial metabolism, biogeochemical function, and ecosystem features. bit.ly/watershedwednesday4 @PNNLab @ENERGY
#WatershedWednesday Inspired by the ecological concept of core and satellite species, molecular characteristics of DOM from 97 river systems worldwide were analyzed using a novel data-driven approach. bit.ly/watershedwednesday3
