The #Petaluma Marsh was once 16,000 acres. Today, only 6,800 remain — and rising seas threaten what's left. A new report from @sfestuaryinstitute.bsky.social proposes using dredged #sediment from the Petaluma River to raise marsh elevations and protect the city from #sealevelrise.

Event flyer for the Anthropocene Sediment Network (ASN) titled “Sand Mining in India” with the ASN logo at the top. Subtitle: “An Anthropocene Sediment Network Focussed Event.” Date and time: Wednesday, 22nd April, 2026, 7:30–9:30 pm (Indian Standard Time) and 3:00–5:00 pm (London Time). Banner reads: “Attendance is free and online.” Programme schedule lists: Introduction (Prantika Bhowmick, Presidency University, Kolkata, India); “Converting rivers to pools: anthropogenic signatures of riverbed sand mining in India” (Priyank Pravin Patel, Presidency University, Kolkata, India); “Sights, sounds and sediments: from shifting rivers to shifty interactions in sand mining sites” (Suraj Gupta, Presidency University, Kolkata, India); Break; “Leveraging India Sand Watch: an online, open repository for evidence-based sediment protection in India” (Siddharth Agarwal, Veditum India Foundation, Kolkata, India); and Q & A and Discussions. A “Sign up HERE!” button points to a QR code. On the right are four speaker headshots. Background photos show river sand mining scenes with excavators, sand piles, water, and a person standing near a mined sandbar.

"Vanishing Sands: Losing Beaches to #Mining" exposes the #sandmining crisis. Written by marine geologist Orrin H. Pilkey and a team of interdisciplinary experts, we learn how sand is ecologically irreplaceable when removed from dynamic #sediment systems.

Flyer for the Anthropocene Sediment Network (ASN) with ASN logo at the top and the title “The Anthropocene Sediment Network.” Tagline: “Empowering community-driven solutions on a changing planet.” Text explains ASN supports collaborations advancing cross-disciplinary communication and research to understand Earth’s Anthropocene sediments. A banner reads: “Membership is free; all events are free and online.” A QR code is shown. On the right, an “Upcoming Events” list includes Sand Mining in India – Wednesday 22nd April and ASN Conference 2026 – Wednesday 27th May with abstract submission open 4th March–6th May, plus the note “Many more events and opportunities are coming up!” Bottom right button says “Sign up HERE!” with the website https://anthrosednet.com/ . Design uses green and gold tones with a stylised skyline and landscape along the bottom.
Thank you for being here! 👋😆

The ASN is a free, open #community for applied, multidisciplinary work on #sediment movement in a #human-shaped world 🌍🌏🌎
At the same time, the system’s behaviour is far from linear — not every intense #rainfall event results in a major debris flow. Internal factors such as subsurface water pathways, #sediment availability, and degrading #permafrost decisively control the dynamics.

Hat der Boden ein Drogenproblem? 💊🌱
Illegale Labore entsorgen Abfälle häufig unsachgemäß – mit teils langfristigen Folgen für Böden und Gewässer.

A picture worth a thousand words: Flood plumes off Cairns today, showing how sediment flows off the land into waterways and out to the ocean and reefs.
Healthy catchments. Healthy reefs. They're not separate conversations.

Yesterday the #Anthropocene #Sediment Network Team met to map out our 2026 event programme! We made some important steps in planning our 2026 conference... watch this space!
If you’re interested in sediment and human impacts, now is a very good time to get involved! Membership is free!
So pleased to finally be sharing the ASN clips from our 2025 conference with you all!
We will be posting one a week now till the summer, so be sure to follow @anthrosednet.bsky.social for much more #multidisciplinary #sediment content!

How does sand mining reshape rivers?
@drchrishackney.bsky.social explores how #sandmining is transforming riverbeds in the #MekongRiver, #Cambodia. His work shows that bedforms become larger, steeper, and rougher than natural ones, altering flow and #sediment dynamics!

What is the ASN? How did it begin? And what are we doing?
Our founder and leader, Dr Catherine Russell, opened the first #Anthropocene #Sediment #Network conference in June 2025.
We’re excited for this #interdisciplinary space for understanding materials and their motion on a human-shaped #Earth!
🧪⚒️🌋2/2 We dig into
• how 2010 #landslide supercharged #sediment supply
• why the #river keeps shifting & raising flood risk
• the human side of hazard communication & resilience
• engineered logjams for stabilizing sediment‑rich rivers
