Summer 2019 Sampling Campaign

Background: The Summer 2019 Sampling (S19S) campaign occurred in summer and early fall of 2019, and sampled surface water and riverbed sediments in 97 globally-distributed river corridor systems. The S19S campaign was designed with the science community to ask questions associated with links among core/transient metabolomes, microbial metabolism, biogeochemical function, and physical properties of watershed and river corridor systems. The data generated will further enable distributed, mechanistic modeling of integrated hydrobiogechemical dynamics within river corridors spanning a broad range of physical-chemical-biological settings. Integration, analysis, and modeling of the resulting data will be facilitated, in part, through collaborations with KBase, the IDEAS project, industry, and academia. The outcome will be transferable data, knowledge, and models focused on mechanistic links among fundamental physical, biological, and chemical processes playing out at the reaction scale, within the context of the broader river corridor.

Spatial coverage

Spatial coverage

Data types:

Surface water only - Anions, cations, total N, specific conductivity, pH, excitation-emission spectra (via Rachel Gabor at Ohio State University), dissolved inorganic carbon, O and H isotopes (EMSL), hydrograph (USGS and others)

Sediment only - Grain size, mineralogy (EMSL), bulk C and N (EMSL), metabolomics by NMR (EMSL), ammonia (via BK Song at VIMS)

Both surface water and sediment - Respiration rate, NPOC, FTICR-MS (EMSL), Mercury (via Oak Ridge National Lab), Extracellular enzymes (via academic collaboration), microbial biomass (via Edo Bar-Zeev and Shai Arnon at Ben-Gurion University of the Negev ), qPCR (16S and ITS), 16S rRNA gene amplicon sequencing, metagenomics (via Joint Genome Institute), metatranscriptomics (via Joint Genome Institute)

Ideas for science questions to explore with the data:

  • What is the magnitude of global variation in respiration rates in sediments and surface waters? How do physical, chemical, and biological processes drive this variation?
  • How do physical properties of bed sediments vary globally? Does that variation drive shifts in microbial gene expression?
  • What universal links exist among watershed features, microbial community composition/function, and molecular details of organic matter?
