#DidYouKnow:#Hydrogen has three main #Isotopes; #Protium, #Deuterium and #Tritium. These isotopes form naturally in nature.

Protium and deuterium are stable. Tritium is radioactive and has a half-life of about 12 years

This week our #UNSW Earth's Systems & Sustainability students have been collecting air samples from around #Sydney. I offered to collect some too, and bags of air are enjoying the train commute from the New South Wales Central Coast.

The samples will be analysed by the students for the greenhouse gas methane. Using isotope analyses, they will identify the sources of the methane in Sydney's air. Will it be leaky city gas infrastructure? Or plumes from industry? Or clean air from offshore?

V nice work w implications for #paleomonsoon reconstructions by Thejna Tharammal, G. Bala, & Jesse Nusbaumer showing using an isotope-enabled climate simulation, that NE monsoon rains over India can be associated with more negative δ¹⁸O signatures than southwest (summer) monsoon #precipitation in spite of being associated with *lesser* rainfall amounts. Interesting to note that the match (or lack thereof) with observations suggests that we still have some ways to go to understand the isotopic controls on this system (seasonality/events?):

Seems like and #introductionpost is how it is done here so here goes. I am a #geobiology enthusiast exited about #biogeochemistry #isotopes #microbes and they all interact on this big beautiful Earth (and beyond). Associate Prof at @northwestern . I am also fond of growing things #gardening #fermentation , cooking, #cats and #knitting. Unapologetic #Feminist. Typos common. #twittermigration

Intro: Just working out this Mastodon thing. As a geologist by training I’m kind of curious about the name and why you would call a social network after a extinct megafauna? A bit about me - I mostly work on oceans and their link to climate through the carbon cycle. I study plankton and biogeochem of the modern ocean, and sediments and isotopes of dead plankton to study the past. I go to sea on large research vessels. I teach oceanography and climate science at an Aus uni. I’m also a cyclist and love to swim in the ocean and hike in the bush and mountains. #oceans #climate #plankton #carbon #ships #isotopes #paleoceanography #Paleoclimates #cycling #hiking

Abstract deadline is coming 01.11.22 for #InquaRoma2023! Submit a talk for session 46 - covering all things biomarkers, #isotopes Pleistocene #archaeology, #climate & habitat variability, and more!

Hi all! I am a #biogeochemist working in the #sciencepolicy space in the U.S.

i talk a lot about #equity, #inclusion and #justice in #STEM bc who does the science shapes scientific outcomes. the scientific enterprise is built upon #colonialism & #patriarchy and thus purposely excludes MANY

i love #isotopes & #ecosystem #science. i hope to use my privilege for good, but know that I have much to learn #lifelonglearner

i also have a fur pack that i love v much

We have a new paper out on a GIANT fossil otter. It was as large as a male lion🦁 & the biggest found yet! The study was led by colleague @CamilleGrohe@twitter.com. #isotopes show it was NOT aquatic like modern otters and shows that it had a wide ranging diet. https://bit.ly/LionSizeOtter

Intrigued by the observation that very few #Wikipedia languages have articles on individual #isotopes, I picked one (#Radium226) to see what #Wikidata knows on the matter - enough for a decent @WDScholia profile https://scholia.toolforge.org/topic/Q4387321 and thus a good basis for Wikipedia entries.
