What to know about Marine Science and Technology

Researchers from the University of Miami and Altametry have developed plastic-webbed drifters to more accurately track the movement of Sargassum seaweed mats. These devices aim to provide continuous trajectory data to improve transport models and help government officials predict when seaweed will wash ashore.

What happened

Plastic-webbed drifters track Sargassum mats for weeks or months at sea Swati Mestri Scientific Editor Robert Egan Senior Editor They spotted the first mat of Sargassum seaweed several miles out in Biscayne Bay.

Why it matters

The captain of the 37-foot (11-meter) Yellowfin brought the vessel to a full stop, allowing the scientists on board to get a closer look at the brown macroalgae that has been washing ashore by the tons this summer and fouling the shorelines of Gulf Coast and…

Common ground

The mat was just what University of Miami oceanographer María Josefina Olascoaga was looking for.

SINGLE SOURCE
While web results show that 'Yellowfin' is a brand of boats and there is a specific 37-foot Yellowfin model for sale in North Miami, there is no independent evidence confirming that a specific vessel of this name and size was used in the context of the event described (bringing the vessel to a full stop).
