Spartina alterniflora invasion stimulates methane emissions in coastal wetlands by increasing labile organic matter and shifting microbial communities Abstract. The invasion of Spartina alterniflora poses a significant threat to coastal wetlands in China. The large biomass and organic substrates introduce

Parallel Factor Analysis for DOM fluorescence Parallel Factor Analysis for DOM fluorescence

We're organizing another run of our #PARAFAC for #DissolvedOrganicMatter fluorescence course starting in March 2026. If you're really interested, DM me with an email address to get reminders about registration (opening in January 2026). Read more: dreem.gitlab.io/coursepage/

Care about fluorescence of #DissolvedOrganicMatter and #PARAFAC? 🚨Update alert 🚨 drEEM version 2 is out! Things have gotten simpler, much faster, FAIR'er, and more interactive. Check it out: dreem.openfluor.org

#RiverDeltas are hot spots of #BiogeochemicalCycling. Yuan Cui et al. analyzed the #SpectroscopicProperties of soil #DissolvedOrganicMatter (DOM) in both freshwater and tidal areas of the #YellowRiverDelta.

🔬 Key highlights:
✅ Detection of 7,000+ molecular formulas across samples
✅ Structural-level characterization for 16% of the molecular space
✅ Integration of MS2 spectral data & in silico structure prediction

What Is the Molecular Weight of “High” Molecular Weight Dissolved Organic Matter? The use of ultrafiltration to isolate high molecular weight dissolved organic matter (HMWDOM) from seawater is a fundamental tool in the environmental organic chemist’s toolbox. Yet, important charact...

I'm stoked to share our work examining the molecular weight distribution of marine HMWDOM! #DissolvedOrganicMatter #NMR

This oblique #AquaMODIS Florida view shows coastal water turned turquoise by seafloor sediments that were mixed upwards when #HurricaneIan plowed through. Near shore, sediment & #dissolvedOrganicMatter from land color the water brown.

Large version here:

#Sediment and #dissolvedOrganicMatter flow from the #MaumeeRiver into western #LakeErie to mingle with #cyanobacteria that have accumulated there. The resulting colors were visible to #Landsat 9 on August 31, 2022.

A broader view is available here.

After break up and in the early stages of green up, #Alaska's #YukonDelta sends loads of sediment and #dissolvedOrganicMatter into the #BeringSea on May 24, 2022.

For those interested, a larger version of the Landsat 9 image is here.
