This is awesome!!

Cary ecologist Taylor Maavara trekked around Mount Everest for 16 days, taking water samples to study carbon emissions from streams fed by melting glaciers. She shares highlights, challenges, preliminary results, and incredible photos here: www.caryinstitute.org/news-insight...

Everyone go see 'Hoppers' ASAP In Pixar's new film, humans and animals fight to block a freeway overpass that would destroy a wetland habitat. It's a brilliant climate parable.

Beaver scientist @emilyfairfax.bsky.social, who consulted with Pixar on "Hoppers," loved the film's message.

Do you have any good tips for doing that method? I’ve tried to find an SOP online but not much luck

Does anyone know if it’s recommended to measure TN/TP on a SEAL with the alkaline potassium persulfate digestion method or acidic potassium persulfate digestion? Thanks!!

Happy World Wetlands Day!

Happy world wetlands day from the wetlands of New York!

Hopefully soon our Cornell Atkinson project will be able to characterize their carbon cycling

EPA & Army Corps Unveil Clear, Durable WOTUS Proposal | US EPA EPA Administrator Lee Zeldin, and Assistant Secretary of the Army for Civil Works Adam Telle, today announced a proposed rule that would establish a clear, durable, common-sense definition of “waters ...

The rule also removes protections for ephemeral streams (waterways that flow only after rain or snow) despite their importance to downstream water quality. In short, this proposal rolls back long-standing protections and leaves millions of acres of waterways more vulnerable to pollution.

ABCFlux v2: Arctic–boreal CO2 and CH4 monthly flux observations and ancillary information across terrestrial and freshwater ecosystems Abstract. Measurements of surface-atmosphere carbon dioxide (CO2) and methane (CH4) fluxes have been relatively sparse across the Arctic tundra and boreal biomes, causing significant uncertainties in ...

It has taken more than two years (plus all the years data contributors have spent on their data collection), but finally our data descriptor manuscript preprint on Arctic-boreal carbon fluxes across terrestrial and freshwater ecosystems is out: essd.copernicus.org/preprints/es... Go have a look!

Using Hydrogeomorphic Features to Quantify Structural and Functional Hydrologic Connectivity in a Coastal Plain Headwater Stream Hydrogeomorphic features provide a key framework to study streamflow generation along the river corridor Across the study watershed, hydrogeomorphic features demonstrated distinct patterns of gro...

super excited to share that my first dissertation chapter is out in WRR!

here, we operationalize the river corridor of a headwater Coastal Plain network into hydrogeomorphic features to characterize hydrologic connectivity across dimensions

Wetlands, Groundwater and Seasonality Influence the Spatial Distribution of Stream Chemistry in a Low-Relief Catchment

What mechanisms underlie near-universal export patterns of dissolved carbon from land to rivers?

Reactions at different depths regulate their directionality (+ or -); subsurface flow paths control strength

Hydrology Paper of the Day @profbobhilton.bsky.social on transport of river-dissolved inorganic carbon on a global scale: isotopic analyses indicating decadal and millennial-age carbon stores; constraining river carbon emissions; and landscape-scale controls in context of the global carbon budget.

Wrapping up your PhD? I’m planning to hire a postdoc in the next few months (start date flexible). Will start formally advertising soon, but you heard it here first!! Possible research topics include - critical zone hydrology, agricultural water quality, SW-GW interactions. Reach out if interested!

Example of how the Surface Water and Ocean Topography (SWOT) satellite's water surface elevation measurements can be used to record flow wave propagation over space and generate a “spatial hydrograph.”

Hydrologists! Ever heard of a Spatial Hydrograph? Our new paper in @agu.org GRL shows that the SWOT satellite can capture spatial flow waves propagating down rivers—something previously only only observable at river gauges: doi.org/10.1029/2024...

The Role of Lithology on Concentration‐Discharge Relationships and Carbon Export in Two Adjacent Headwater Catchments Bedrock lithology drives differences in streamflow and carbon export in adjacent catchments, controlling variability in shallow flow paths Both catchments display similar in-stream major ion conc...

Latest paper out of the WS hydrology lab! Here we show spatial variability in lithology is important for streamflow behavior and carbon export, but geogenic solute export behavior is similar. agupubs.onlinelibrary.wiley.com/doi/full/10....
