BIG CONGRATS to #AdriftLab MSc candidate Meg who completed her final seminar on #microplastics in #ports yesterday 🥳. Over the past 9 months, she did an amazing job trialing methods to find one that actually works for #sediments (this was a huge achievement in its own right and the lessons learned will greatly benefit the broader #plastics community) 👏

🚨🚨New Paper Alert🚨🚨
We have a new paper out in Earth & Planetary Science Letters (#EPSL) entitled “Indian margin methane hydrate dissociation recorded in the carbon isotopes of benthic (Miliolida) foraminifera”
Main take home message: we have identified a group of #benthic #foraminifera (unicellular organisms living at the bottom of the #ocean) whose shell chemistry carries signatures of #methane dynamics within #marine #sediments.

Happy to share our new publication from the #ClayHOC project: #Adsorption of the #hydrophobic organic pollutant #hexachlorobenzene to phyllosilicate #minerals in ESPR
https://doi.org/10.1007/s11356-022-24818-4
Results show relevant #adsorption of #HCB to natural #ClayMinerals. Cation-modification revealed dependence on type, radius, #hydration enthalpy of exchangeable #cations
Results support relevance of minerals for #EnvironmentalFate of #PersistentOrganicPollutants #POP in #soils #sediments

Anaerobic methanotrophic #archaea play a key role in removal of #methane in deep sea #sediments
This new #metagenomics research explores the genetics of the ANME-1 'Candidatus Methanophagales' order and the critical role that #viruses may play in shaping and expanding their metabolic repertoire and #evolution

For #FossilFriday meet what we can *probably* consider the oldest body #fossil of a land #animal (until we find more, older fossils) - this is Casiogrammus. It's a millipede preserved in rocks from 🏴 that are ~430–433 million years old.
It was entombed in #sediments that were probably at the bottom of a relatively permanent lake.

🚨NEW PAPER ALERT🚨 recent #AdriftLab MSc graduate Karli Mylius has published her first, first-author paper - yay yay👏
Our research focused on the ingestion of #nanoplastics by #shorebirds as few data exist, globally. To do this, we also collected data on #plastic particles in beach #sediments from locations where we saw the birds actively feeding in #Tasmania.
We studied #HoodedPlover (Vulnerable species) and #PiedOystercatcher (📸 credit Eric J Woehler) & found 1000s of tiny plastics in ALL of the birds and sediments we examined, no matter how remote the location.
Hooded Plovers have shorter beaks, and because of this, they feed in shallower (surface) sediments where more plastic has been shown to accumulate. Not surprisingly, their #guano 💩 contained 32× more plastics, on average, than Pied Oystercatchers! 😳😢
We gratefully acknowledge the #TraditionalOwners of lutruwita, where this research was undertaken and funding from BirdLife TAS and a generous philanthropist who directly supported both students involved in this project during the 2022 cost of living crisis.

@ionferrico also presented a poster on #MikrobioGune, about association networks based on #metagenomes of a time series from #estuary #sediments. In summary, very cool and exploratory stuff. Not that easy to interpret ecologically, but we're working on it

Nice walk today on the beach on Petit Manan Peninsula in Downeast Maine. Great ripples in the intertidal. #ripples #Downeast #Maine #sediments

Quick introductory post: I am Katharina, a marine #geophysicist with the University of Tasmania #UTAS. I am interested to understand how #ice sheets, #oceans and #sediments interact in the past, present and future. ❄️🌨️🌊🚢🐧

Earth Hasn’t Warmed This Fast in Tens of Millions of Years
Chemical analyses of ancient #sediments allowed scientists to put together one of the most comprehensive #climate #histories of the planet.
,,,They found that the planet has passed through four distinct climate phases: #warmhouse, #hothouse, #coolhouse and #icehouse states.
Transitions from one state to another have generally depended on changing
#GreenhouseGas levels.
