By: Dyllan Furness, Director of Communications A yellow-brown seaweed called Sargassum has become an annual problem for communities across Florida, the Caribbean, and Gulf Coast. Since 2011, large mats of Sargassum wash ashore each spring and summer. Where they decay, they emit a foul rotting odor, harm marine life, and disrupt local communities.

By: Dyllan Furness, Director of Communications A new study led by researchers at the University of South Florida shines light on the environmental drivers of red tide blooms. Published in the American Society for Microbiology’s journal mSphere, the study is the first to identify viruses associated with Karenia brevis, the single-celled organism that causes red tide.

By: Dyllan Furness, Director of Communications There’s often little warning when a tsunami strikes, but a research team at USF aims to improve the forecasting of these hazardous events for communities that are most at risk. The Shallow Underwater Buoy for Geodesy (SUBGEO) system is a research partnership between the USF School of Geosciences, the College of Marine Science (CMS), and international collaborators.

Credit: Alex FoxThe ocean’s twilight zone is iron-deficient, limiting bacterial growth and affecting carbon storage. New findings show high siderophore levels in deeper waters, indicating a broader impact on marine biogeochemical cycles and necessitating further study.

By Dyllan Furness, Florida Flood Hub for Applied Research and InnovationSea surface temperatures are on the rise around the world, but the problem is pronounced in the estuaries and shallow coastal waters of South Florida. In South Florida, estuaries have experienced rapid warming over the past two decades.

By Dyllan Furness, Florida Flood Hub for Applied Research and InnovationThere’s never a dull moment in the Ocean Circulation Lab at the USF College of Marine Science. Surface buoys need maintenance. Bottom mounts equipped with ocean monitoring instruments need to be recovered from the seafloor. When hurricane season rolls around, busy gets a new meaning for the lab, which operates several high-resolution models that forecast currents and water levels along the western coast of Florida.

By Dyllan Furness, The Florida Flood HubFrom the air to sea, small things can have big impacts on our planet. Aquatic microorganisms known as phytoplankton serve as photosynthesizing powerhouses, producing more than half of Earth’s oxygen. Aerosols — often-invisible particles suspended in the atmosphere — can have significant influence on Earth’s climate, weather, public health and ecology.

By Dyllan Furness, The Florida Flood HubA parasite that devastated long-spined sea urchins in the Caribbean and Florida in 2022 has caused another die-off more than 7,000 miles away in the Sea of Oman. The discovery, led by researchers at the University of South Florida College of Marine Science (USF CMS) and recently published in The ISME Journal, reveals how the spread of a microscopic pathogen threatens sea urchin populations and coral reefs around the world.
