August 20th is coming up!
If you're researching nearshore sediment transport, please consider submitting an abstract to the #AGU Ocean Sciences Meeting 2026 session, CP012: Sediment Transport in the Nearshore Ocean: Insights from Field, Laboratory, and Numerical Experiments. agu.confex.com/agu/osm26/pr...
if you're insterested in river nutrient dynamics, sediment transport, river restoration, etc., please check out our new paper on the impact of boulders on oxygen levels in streambeds.

Impressive hummingbird aerodynamics in Durham, NH. They beat their wings at around 40 Hz (this is a Live Photo, so not very high frame rate). Check this link for a fun fact about hummingbirds from @nicolesharp.com

Lithified wave-formed sand ripples.
Plaque saying wave-formed ripples are symmetrical.
Lithified current-formed sand ripples.
Plaques saying asymmetrical ripples shape shows flow direction.
I saw a relevant exhibit in the Natural History Museum in London today. They have lithified sand ripples, one set formed by waves and one by current.
Happy late #FlumeFriday. Here is a top view of sand ripples formed in the EFWT at UNH using oscillations of an amplitude 8 cm and a period of 2 s. The distance between ripple crests is about 6 cm and the sand is fine (median gran size is around 0.2 mm). these ripples affect coastline evolution.
The above paper, along with agupubs.onlinelibrary.wiley.com/doi/full/10...., describe a novel approach for calculating the pressure field from standard (e.g., at 11 Hz sampling frequency) stereo or tomographic particle image velocimetry.
A new article by Monsalve et al. describes how data from lab experiments and numerical simulation were used to investigate physical forces that influence water quality and GHG emissions of rivers, particularly the role of gravel and plants. (Free for 50 days). authors.elsevier.com/c/1knyB16J1n...

Updated to *3* CEPS professors! Incredibly excited and honored to lead this project studying the physical mechanisms that drive marine disease transmission in seagrass and coral ecosystems www.unh.edu/unhtoday/202...
Happy #FlumeFriday! I started making sand ripples in the environmental flows water tunnel at #UNH. The oscillatory flow pushes the sand at the crests back and forth and creates vortices downstream (leeward side) of the ripples.
so true! There are interesting fluid phenomena all around us!
Awesome! The more volunteers who help track and combat these changes the better. That seems like a fun way to give back.
