My colleagues at the Nutrient Management Strategy at @sfestuaryinstitute.bsky.social have published for the first time our moored station dataset, with 15-min biogeochemical data from 11 stations surrounding SF Bay, some of them going back to 2013! www.sfei.org/data/san-fra...

Bringing these back because love for the San Francisco Estuary never gets old. Which Valentine would you be most excited to get? Click each image to see the full Valentine. #ThrowbackThursday #bayarea #climateresilience

Our scientists have been hard at work drafting the first statewide strategy to monitor plastic waste across California. Please share among organizations involved in monitoring plastics in California and leave a comment! www.sfei.org/projects/sta...

I stumbled on an @sfestuaryinstitute.bsky.social “State of the Estuary” report from 1992 and this is easily my favorite graphic. Birbs here. More birbs over there.

I've been at @sfestuaryinstitute.bsky.social for 4 years! During this time I've become a hardcore estuary/wetland stan. This Bay surprises me in the data every day! I love to look at it and marvel at its greatness and mystery. At the end of the day, I continue to do it for the clams tho!

Chabot looks back on his time at SFEI with gratitude. “I was given the privilege of serving 50 brilliant, passionate, public interest scientists. There are now almost 100 of them. It was the best decade of my professional life.” 🧵 2/3

In his decade of service as executive director at the San Francisco Estuary Institute, Warner Chabot worked to build partnerships across agencies and elevate the Institute's science while maintaining what he called its "platinum reputation." @sfestuaryinstitute.bsky.social 🧵 1/3

Master's student Emet Levy in the Department of Design at San Francisco State University was inspired to animate some key findings from our San Francisco Bay Microplastics Study! Check it out. What other studies would you like to see as animations?

We hit a milestone this November! Californians interested in how streams and wetlands are doing can now view more than 10,000 field assessments collected with the California Rapid Assessment Method (CRAM) on EcoAtlas, from big cities to remote corners of the state.

“I was given the privilege of serving 50 brilliant, passionate, public interest scientists. There are now almost 100 of them. It was the best decade of my professional life." Thank you Warner Chabot, who recently retired from SFEI after 11 years of dedicated service as our executive director!

There are hundreds of chemicals in tires. In 2020, our scientists were part of a team that discovered one that's so deadly for coho salmon that they'd die from less than a drop in an Olympic-sized pool.

There’s still time to make an impact this year! We’re just ✨6 gifts✨ away from our year-end goal of 80. Help us cross the finish line by donating today → sfei.org/giving

Clean Water scientist Kayli Paterson had a different kind of scientific poster at the recent @setac.bsky.social North America meeting. Her original artwork brought to life how community scientists sampled laundry lint vented outside their buildings as a possible major source of microplastics.

OPEs replaced older flame retardants in the 2000s. They were meant to be safer, but are linked to neurological harm. Many OPEs can also increase cancer risk and disrupt hormones, reproduction, and development.

This #GivingTuesday, help SFEI get 36 donations to keep Bay Area science responsive and community-rooted. With 97% of our funding from government sources, diversifying support is essential. Donations up to $500 will be matched! Donate any amount today. 👉 sfei.org/giving

Senior scientist Ezra Miller was interviewed for this article about microplastics. Their advice: “source control” is “the most effective and the most societally cost-effective” way to reduce microplastics.

Matthew Héberger, one of our Clean Water scientists, was quoted as an expert in this article. He emphasizes that improved water quality will require ongoing commitment.

Final day to submit your best ideas for naming our stormwater sampling robots! Learn more: www.sfei.org/news/help-us... #NationalWaterQualityMonth #SanFranciscoBay
