🌊A critical study reviewing the impact of the DWH oil spill was recently published in #AGUPubs. Great job by College of Marine Science Professor Kendra Daly!

Thanks for sharing! An important study by College of Marine Science Professor Kendra Daly 🌊

This project was conducted with researchers from Sea Education Association, Eckerd College, Woods Hole Oceanographic Institution and Florida Atlantic University.

Researchers at the University of South Florida College of Marine Science used satellite data gathered by NASA to observe these changes in sargassum biomass.

🌊The dominant location of sargassum is shifting according to a study published in Nature Geoscience.

While some regions such as the Caribbean have experienced unprecedented growth of sargassum, the historic location of the seaweed in the Sargasso Sea has seen drastic declines in the past decade.

Welcome 🌊

From presenting new findings to building international collaborations and learning alongside scientists from around the world, it’s always an incredible opportunity to connect, exchange ideas and advance ocean science together @agu.org #OSM26

Greetings from across the pond 🌊

Faculty, staff, students and alumni from the College of Marine Science recently shared their latest research at the AGU's Ocean Sciences Meeting in Glasgow, Scotland.

Gag grouper are overfished in the Gulf. This new tool could help The new approach “provides a flexible tool to support decision making, particularly for vulnerable, highly targeted stocks,” according to the authors.

🌊Gag groupers are an angler favorite in the Gulf — but right now, they’re overfished 🎣
Learn how a new model from University of South Florida and Fish and Wildlife Research Institute may improve management of this struggling species.

Man standing near lecture showing a beautiful electron microscopy image of phage infecting SAR11. He carried a genomes as great books analogy through his talk - this slide is called “War and Peace (SAR11 prophage)”

Great seminar by Bob Morris @cmarinescience.bsky.social today! @cninaphore.bsky.social and I are lucky to be collaborating with him on the hunt for SUP05 phage #NSFfunded #phagesky 🦠🌊

🌊We thought it was cold here… ❄️

Meanwhile, @margaretbrisbin.bsky.social is in the Weddell Sea aboard the R/V Sikuliaq, studying how melting Antarctic sea ice is reshaping microbes and ocean life as part of NSF-funded research 🌊🧪

🌊🧪 At the 2026 State of Science, Steve Murawski of the University of South Florida College of Marine Science shared insights from the Tampa Bay Surveillance Project, which is studying contaminants in local waters and their impacts on ecosystems and community health.

Where do seashells come from? Seashells are the skeletons of sea creatures – and they’re older than you might think.

No new science news from us bc we’ve been “Shackletoned”-stuck and drifting with the ice for a few days now. Hoping a big storm will blow us out tomorrow so we can finally get back to work! Drone photo is by Dr Ellen Buckley, diatoms & filmentous ice algae are from the ice station #oceanography 🐧🇦🇶🌊

Incredible images!

Scientists harness AI to discover a rise in floating algae across the global ocean Authors of the new paper in Nature Communications attributed the bloom expansions to both human activities, such as nutrient runoff into the ocean, and climate variability, such as ocean warming.

🌊AI meets ocean science 🌎 New research led by USF and NOAA reveals a global rise in floating algae, signaling a major shift in ocean conditions with wide-ranging impacts on ecosystems, tourism, and coastal economies.

🎉 Congratulations to Chuanmin Hu on his recent election as a Fellow of The Oceanography Society!

Hu was nominated for his work on optical oceanography and satellite remote sensing. Among Hu’s contributions is his landmark work characterizing the Great Atlantic Sargassum Belt.

Applications are still open!

We were so excited to host the City of St Pete Mayor, Ken Welch, at the USF College of Marine Science outreach center, Clam Bayou Marine Education Center! During his visit, Mayor Welch was able to observe the students as they engaged in hands-on field work.

The study was a collaboration between the University of South Florida College of Marine Science, Sea Education Association, Eckerd College, @whoi.edu, and Florida Atlantic University.

Study reveals dramatic decline in some historic sargassum populations Certain populations of sargassum have plummeted in abundance over the past ten years, raising alarm for marine ecosystems that depend on the seaweed.

A new study published this week in Nature Geoscience found that while tropical Atlantic is experiencing a significant increase in sargassum, abundance of the seaweed is declining in its historic habitats of the Gulf and Sargasso Sea.
