Water density and the location of extraction play a crucial role in minimizing environmental impacts from lithium mining in sensitive salt flat ecosystems. Sustainable practices depend on prioritizing brine over freshwater use. doi.org/g93x7h

Water's density is key to sustainable lithium mining, study reveals

One of the biggest obstacles on the road to a low-carbon energy future is caused by the rare-earth element lithium, a critical component for the batteries that can store the abundant and sustainable energy from renewable sources.

Cape Cod is composed of thick glacial outwash sediments with few streams (although abundant ponds), deeper water tables that respond more slowly to interannual variations in precipitation. These responses control how quickly each system will recover as the drought subsides.

Prof. David Boutt @davidboutt.bsky.social · 27d

While differences in precipitation deficits exist, the water storage response is controlled by the hydrogeology of the region. CT river valley is characterized by abundant surface streams with shallow water tables and relatively thin sediments and soils that respond quickly to seasonal water balance

As the 2025 drought continues here in the Northeast (not to be confused with the 2016, 2020, 2022, or 2024) terrestrial water storage anomalies respond in different environments in distinct ways. Take for example storage anomalies in the CT river valley of Western Mass compared to those on Cape Cod

Once again a significant drought beginning to develop here in S. NE. Our new groundwater storage deficit analysis shows that 5 out of the last 9 yrs in a drought state. Interestingly switching from record wet to very dry (see 18, 21, 23) and to some extent last spring. @climatechris.bsky.social

Actually dry enough to qualify as one of the driest summers on record for portions of New England. We'll see if tomorrow's rain chance alters any of these rankings

Likely going to see early leaf drop/more browning of leaves than usual

We are actively monitoring the developing drought on Cape Cod using USGS and @massdcr.bsky.social supported observation well data. Custom built codes and scripting by @umassamherst.bsky.social undergraduate Gabriel Olland to track trajectory of water storage. @umasshydro.bsky.social

Can you link the Webmap or GIS map again here? Thanks for doing this work and excited to read it in detail and share with students!

The USGS office that monitors all metro Atlanta rivers (and much more) is set to close at the end of August.

Congress has just released a list of federal DOI offices to be closed under the ongoing massacre of our natural resource agencies -- it's extensive and includes many important NPS, BLM, USGS and USFWS facilities across the country. Truly horrific. democrats-naturalresources.house.gov/imo/media/do...

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...

National Science Foundation fires roughly 10% of its workforce

NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.

I can only HIGHLY recommend this book by my good friend James McNamara (professor of hydrology) In The Wake: An 80 Day Canoe Odyssey into Canada's Northern Wilderness. In 1991 they loaded a canoe with food for 3 months and paddled into the canoe county of northern Canada. You can order via amazon.

A little bit delayed, but I hear it's picking up over here so sending this out into the world: our Lafayette team including Rachel Hurley (now grad student at WPI), Dave Brandes, and me put out this piece on flashiness across the Mid-Atlantic: onlinelibrary.wiley.com/doi/abs/10.1...

Drivers and Buffers of Stream Flashiness in the Mid‐Atlantic United States

In this study, we investigated flashiness across 195 Mid-Atlantic sites, each within one of seven different physiographic regions. Our findings identified several drivers and buffers of flashiness, e...

I did a quick analysis of groundwater levels - which track terrestrial water storage anomalies quite well- and were about 50% recovered already. Should be on track for headwater baseflows to be in the normal range for spring.

Did NOT see this coming!!

Analysis of 2.9M rivers globally finds that, on avg 1984-2018, streamflow increased in headwaters & declined in downstream sections (1.7 times more upstream increases found than declines; ~4 times more downstream declines than increases).

More flow upstream and less flow downstream: The changing form and function of global rivers

We mapped daily streamflow from 1984 to 2018 in approximately 2.9 million rivers to assess recent changes to global river systems. We found that river outlets were dominated by significant decreases i...
