"The press have repeated a statement initially peddled by #TEPCO, that this contaminated water only includes #tritium. This is untrue, and tritium is not without its own risks. The water being discussed has been through the various filtration systems on site used to remove #radioactive #isotopes. Each system removes some of the radioactive elements in the water. ALPS is the last of these systems. It can remove much of the remaining contamination but not all of it, some radioactive contamination remains in this water.

"We [SimplyInfo] documented back in 2018 that this water contains other problematic radioactive elements including:

#Plutonium (238, 239, 240)
#Americium
Iodine 129
#Technetium 99
Cobalt 60
Curium 244
Niobium-94
#Europium (152, 154)
#Cesium 137
#Strontium 90
Selenium 79
Nickel 63
Tin 126 (aka: Sn-126)

"As of 2018 the stored post ALPS water contained 200 billion becquerels of iodine 129, #ruthenium 106, and technetium 99. As stored water increases, so does the total volume of contamination within that water.

"TEPCO and the Japanese government have tried to ease concerns by claiming the water will be diluted before it is dumped into the Pacific ocean. This is a meaningless step. The total amount of radioactive contamination is still dumped into the ocean, you just dumped some additional water beside it at the same time."

>In sedimentary basins, the evolution of hydrocarbon including oil/gas generation, migration, and accumulation, as well as reservoir destruction, is often controlled by regional tectonic activities.

Still needing a proper "Hello" toot – Hi there! I am Tobias, geoecologist running a #biogeochemistry lab in Berlin. Truly amazed by the chemical machinery of our planet and all things #water! My research is in oceans, rivers and lakes and deals with #waterquality #nutrients #carbon #pollution #isotopes. Looking forward to make #sciencemastodon a thing! Further musings likely include #bikes, #cycling, and #mobility change (did I say bikes?)

New Paper:

Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes

TL;DR:

(1) Deeper lakes retain less freshet runoff, since vertical mixing was likely more limited in deeper lakes

(2) The freshet runoff that mixed into lakes was a mix of snow- and soil-sourced water. The initial mostly snow-sourced freshet that flowed into lakes was likely replaced by more soil-sourced freshet later on.

By measuring rare oxygen isotopes, a team of geochemists has developped a technique to deduce long-ago global temperatures 10 kilometers up in the atmosphere, creating, in effect, a paleo–weather balloon. This technique will help scientists study past climates, not only to better understand what conditions were like as life evolved, but also to ground-truth computer models’ predictions about global warming.

Introduction! I'm a #palaeontologist and #geochemist interested in organism & ecosystem response to environmental change. I use #fossil #molluscs and #microfossils, #isotopes #CTscanning & #Morphometrics & do a lot of #fieldwork. I've worked a lot on the end-#Cretaceous mass #extinction (especially in #Antarctica!) but dabble throughout Earth History. Looking forward to exploring the new place! :mastogrin:

I just joined and this is my first post! Should I switch to ecoevo.social? I didn't see that as an option when I signed up.

I'll include some hash tags in the hopes it will make it easier to connect with folks: #ecology #evolution #academia #globalchange #foodwebs #aquatic #terrestrial #urban #water #science #sustainability #isotopes #climate #biogeochemistry

At the moment this site feels a little like the awkward first days of a #conference where you don't really know anyone and are wondering what the etiquette is.. At some point the posters will go up and the refreshments will come out...

A new #openaccess paper from the talented Haoyu Diao on uncertainties in #plant #water #isotopes. Importantly, Haoyu shows that artifacts associated with cryogenic vacuum distillation are minimal when the sample has enough water in it: https://hess.copernicus.org/articles/26/5835/2022/

After 3.7 Ma hominins had highly varied diets isotopically--both tree products and monocots were consumed. On average they filled carbon isotope space between C3 browsers and C4 grazers. But then at 2.3 Ma the genus Paranthropus goes berserk and moves into the isotope space of the numerically dominant grazing herbivores. How they pulled this off so successfully, and without teeth seemingly suited for grass consumption, remains a bit mystifying. #fossils #hominins #diet #evolution #isotopes
