“It’s a term that belongs to everyone. To people working in philosophy and literary criticism, in the arts, in the humanities, the sciences” After 15 years, geologists decided that the Anthropocene will not become an official epoch in Earth’s timeline go.nature.com/43psd8U

Our editorial this week focuses on a timely question - Are we in the Anthropocene yet? The absence of an agreed marker and a specific start date should not detract from the reality of a discernible human fingerprint on Earth systems. #natureeditorial nature.com/articles/d4158…

A bit late, but here is my #day1 entry "Part-to-whole" for #30DayChartChallenge It's from a paper under review, so let's label it as "preliminary". Made with #ggplot2 #Rstats, based on drinking water data from Jupiter database geus.dk/produkter-ydel… black line - right side axis

"Makeover" #day3 of #30DayChartChallenge In 2021 we published a paper about As in drinking water and the effect of lowering the Danish standard from 50 to 5 μg/L (pubs.acs.org/doi/10.1021/ac…). I gave a makeover of the original figures (here shown Fig. 3). Not sure it is better :)

My 1st waffle ever! #day4 of #30DayChartChallenge It shows average 24 hours within my work week. I work, while commuting sometimes. The color palette is "Pairings" from #Pantone featuring the color of 2024 #PeachFuzz (#FFBE98) in the "work" category. pantone.com/color-of-the-y…

We introduce the United States Groundwater Well Database (USGWD), which contains 14.2+ million use and monitoring wells across the US. 1/9 Paper: rdcu.be/dDGDY Data: hydroshare.org/resource/8b028…

A paper in Nature Geoscience suggests that a large fraction of global water resources may be contaminated by per- and polyfluoroalkyl substances (PFAS) at levels that exceed some national regulations. go.nature.com/3U56aBb

trying out Quarto documents in #RStudio... does that count as #30DayChartChallenge? I have been a bit behind with the new things, so I thought I should finally have a look.

Major/Minor #day9 #30DayChartChallenge Distribution of selected major, minor, and trace elements in groundwater. Incl. only the monitoring wells with iodine data (GRUMO). The vertical lines are at 0.01, 0.1, 5 mg/L (Figure 50 of books.gw-project.org/groundwater-in…) The Groundwater Project #ggplot2

New Maximum Contaminant Levels (MCLs) on PFAS in drinking water by USEPA. Four compounds get individual enforceable limits (PFOA, PFOS, PFHxS, PFNA, and HFPO-DA), plus one for mixtures. See details here epa.gov/sdwa/and-polyf…

Here's some personal time-series :) Sofie's shoes (missing two pairs from when she could not walk yet). and that's my dose of daily procrastination while revising a manuscript. This fits with #day10, #day13, and #day15 of #30DayChartChallenge

I’m preparing a short #Rstats course for some of my colleagues focused on the routine groundwater & drinking water analyses we do. I thought I could reuse my tutorials from NUS (2018). Great mistake! Maybe 5-10% only, my coding style has changed so much! Base R to tidy R.

I’ve had only good experience with the peer-review and publishing process at GEUS Bulletin Ppl are very focused on prestige (h-index), which takes time and collective effort. Let’s make it prestigious (at least in EU & earth sciences)!

last entry for the #30DayChartChallenge, #day28 #trends: few years back I made this R shiny app, which allows you to explore the effect of parameter choice on the local polynomial regression (loess): denitzav.shinyapps.io/loess/ a blog post about it: water-research.info/my-first-shiny… base R :)

that's a very nice overview figure, I think.

Here is what happens, if you ask #Copilot to create some figures/logos for groundwater research or #groundwater and #Denmark. It was fun :) All results with the exact prompts are in the link: water-research.info/copilot-figure…

Updated R Studio and everything works painfully slow on the network drives. Basically cannot work. Even opening a simple R script is taking few minutes. I found few suggested solutions, but they all work only for some people, so I’m dreading the process of fixing this problem.
