A grain shape chart that provides the basis for objective assessment of texture and roundness of a grain. The top row is density of texture and the intensity of the texture in cross-section showing very high, high, moderate, low, none. The bottom row is for roundness from very angular, angular, subangular, surrounded, rounded, to very rounded. Each grain can be described objectively through these texture and roundness analysis. Figure is Figure 6 in Russell et al., 2025

📢 #Microplastic folks, let’s rethink how we use “fragment” for angular particles 🔷

“Fragment” implies a secondary microplastic, but primary #plastics can start angular too!

Use the grain shape chart below instead:

Australia sees nearly 40% decline in plastic pollution along major city coastlines Country has pledged to phase out unnecessary plastics by 2025 and recycle or reuse all its plastic waste by 2040

✨Good news!✨

Australia’s seen a 40% drop in #plasticpollution on major beaches!🏖️

They’ve pledged to phase out unnecessary plastics by 2025 & reuse or recycle all plastic waste by 2040♻️

It’s PROOF that action works! Let’s keep going!

This is so exciting! 😆

It’s going to be a SUPER opportunity to present and discuss what moves on Earth and why… in a multidisciplinary space 🌍

Please share with anyone who you think would be interested ✨

Our latest work suggests that rivers don’t just transport and store microplastics — they actively create them through fluvial process-driven fragmentation of macroplastics!

I am ✨BEYOND✨ excited to share my “Classification Framework for Assessing #Anthropogenic #Sedimentary Facies”!

It covers composition, bed- and grain-scale descriptors, structures, and nomenclature.

Now we can describe the developing #sedimentology of #Anthropocene #Earth 🌍

Together with Luca Gallitelli @riverinelitter.bsky.social, we show that wood jams can retain up to 600× more macroplastic than channel sediments. We introduce the term plastic-wood jam to describe this phenomenon. doi.org/10.1007/s107... #Macroplastics #Hydrobiologia #RiverPollution
