“In terms of quality, dams act as natural settling basins, similar to . They back up water for varying periods, capturing and allowing the natural microbes and plants to process excess such as nitrate. The researchers have found that, in general, nitrogen processing in the pools behind the beaver dams is reducing nitrate concentrations leaving the pools by several milligrams per liter during period of higher rainfall like late spring and early summer compared to water from stream reaches above the dam.

“That may not sound like a lot,” Beck said, “but it can significantly reduce total nutrient loads leaving the .”

These retention ponds also impact watershed by slowing runoff from the landscape.

“Especially in smaller watersheds, it looks like the 😂 dams can make a difference by reducing the energy of flow during high water and associated erosion and sediment transport.”

@luke I get citations of my Jurassic Morrison Formation papers in Mars Desert Research station publications all the time. They rival those from the dinosaur folks! Never know who is going to find your research of value!

@seelix “Pebble” is a defined grain size classification on the Wentworth scale for sediments

jstor.org/stable/30063207#meta

As a sedimentologist, I’m intrigued by the brand name, but I think “Fruity Phenocrysts” sounds fun, and “Fruity Porphyroblasts” sounds even funner.

Aeolian sands from a glacial age
Form terraces suitable for abodes
Rising seas diminish their defenses
Not rip-rap, not beach grass, not sand fences
Who will be the last, when the cliff erodes

Less exotic in the end, but equally puzzling at the outset were pebbles handed down to me by my grandmother. They were heavy for their size and marked as being from Colorado. All I knew at that point.

A quick density measurement and cracking one open confirmed they were galena pebbles that were oxidized on their exteriors.

Sorry I broke one, grandma, but you were one of the people who stoked my interest in science!
