New pre-print: groundwater recharge in Australia. - Annual rainfall recharge thresholds (RRT) are similar everywhere. Seasonality is pronounced; recharge is rare in summer or autumn. This should be accounted for in groundwater modelling and management. essopenarchive.org/users/100201...

It’s not what you have, it’s how you use it—even when it comes to the distribution of dissolved organic carbon in the ocean. The type of DOC is less important than how many bacteria are around to eat it, modeling suggests. eos.org/research-spo...

As a rare climate scientist working in Silicon Valley, I've been drinking from the AI firehose a lot more than my peers. I thought it would be helpful to lay out my experiences of both the promise and pitfalls of using AI to accelerate scientific research:

On stealth corrections to the academic record. That is, changes made by the publisher after publication, with no notice given. Guess what? MDPI are caught moving articles out of special issues post. Read more in this blog deevybee.blogspot.com/2026/02/gues...

Really SVP? You’re just going to ignore decades of sexual and academic misconduct, marrying a student AT one of your conferences, and every report I’ve filed (implying that’s what you do with reports) to defend famous Horner? You’d rather have pedophiles than students is your message?

We took delivery of a new ABB off axis water isotopes analyser today here at UNSW, to replace our 10 year old instrument. It was a good day in lab with spanners and swagelocks. To be continued tomorrow....

Heliyon has published fewer papers and ramped up its retractions since a major indexing service put the journal on hold and the publisher launched an audit of all papers published in the journal since its launch in 2016.

A shout out for Quaternary researchers - registration and abstracts are open for the 2026 Australasian Quaternary Association conference. Come to UNSW Sydney in July. Details are here: aqua.org.au/conference/a... Abstract deadline: 28 Feb.

Forget pickles and ice cream. I published a fake paper on pregnancy cravings for prime numbers.

Any NOLA peeps recognize this very sweet boy? Just found him running across Canal st in mid city. Followed a friend to The Station coffee where I snagged him (and many many many kisses)

For Sydneysiders: I walked the GreenWay this week, and recommend it. Great art and interpretation, and easy access from L1 Light Rail stations. Good for walking and cycling - I have to go back on the bike and explore the connecting cycleways.

Elsevier has pulled a dozen papers by a finance professor in Ireland who oversaw the review of the articles and made “the final decision” to publish them in three journals he edited, according to the retraction notices.

Some New Year's data wrangling with a messy time series with skewed properties, missing and poor quality data at times, different recording techniques, human error, etc. x-axis is time in years, y axis is kilometers. The hashing is #running

Hydrology Paper of the Day @andy-baker.bsky.social on quantifying the drip of water underground as part of rainfall recharge: groundwater monitoring near the water table in Australia; why mines, tunnels and caves are essential monitoring locations; and relating rock aquifer response to rainfall.

Exploring Drip Water Dynamics for Groundwater Recharge The end of the year is approaching, and the papers and pre-prints are still coming from the groundwater and climate research team here and our collaborators. Here is a summary of our outputs the last three months of the year. All are…

Wildfire smoke, already a health hazard, may come with a dangerous hitchhiker: fungal spores. Research presented at #AGU25 by @kobziar.bsky.social, @phin-lampman.bsky.social, & colleagues. eos.org/articles/fun...

Attendance at US-based science conferences is bouncing around this year but generally down. #AGU25 has ~10k fewer this year! I explored these trends for @nature.com — including solutions to keep conferences local & productive: www.nature.com/articles/d41... 🧪

Eurokarst 2026 This is an international meeting on the hydrogeology of karstified Rocks - think caves, limestone and chalk and their water resources. Which is held in Europe. Hence the title. The abstract deadline is now open, and closes 15th January. Pass the word! www.eurokarst.org

First update from STOTEN in a while. Yet none of these ongoing issues are obvious from STOTEN's homepage. I'd be annoyed if I had been unaware and published with them in the past year.

No OSPA at this year's #AGU25, which is disappointing, because it made sure that students had at least 3 scientists come to their poster, ask questions, and provide anonymous (hopefully productive) feedback afterwards. Does anyone know why it was dropped? @hydrology-agu.bsky.social or @agu.org

We have a new position paper, where we advocate for the wider use of underground observatories to understand how groundwater is replenished. By directly observing these recharge events, we can make a direct link between groundwater replenishment, weather and climate. eos.org/science-upda...

And if you adviser isn't the type to do this - find another champion for your career. Endlessly thankful for people like @microgem.bsky.social who reached out to support my career in many ways!

It's over. Despite the fact that the academic council recommended against it, despite the fact that the program brought in more tuition than it cost, and despite the fact that Nebraskans need & deserve this expertise, Earth & Atmospheric Sciences will be cut. www.dailynebraskan.com/news/adminis...

Collapse of key Atlantic current could bring extreme drought to Europe for centuries, study finds. @swinda.bsky.social That's an under-appreciated impact of #AMOC shutdown, of particular concern given the recent results showing much higher likelihood of this. 1/2 www.livescience.com/planet-earth...
