FAU Developed AUTOHOLO Shows Potential as Red Tide Warning System

Current methods to monitor red tide are limited. Using AUTOHOLO, a new autonomous, submersible, 3D holographic microscope and imaging system, a study is the first to characterize red tide in the field and breaks new ground for monitoring harmful algal blooms.

FAU Lands $736,000 from NASA to Study the Coastal Carbon Budget from Space

If successful, this research in the Gulf of Mexico’s hypoxia region off the coasts of Texas and Louisiana may demonstrate not just the ability, but also the utility, of remote sensing as an observational technique for characterizing potentially critical but often neglected carbon cycle processes related to marine sediments. Researchers will use satellite images, hydrodynamic modeling and field work in seeking a better understanding of the ocean’s role in the Earth system.

Explosive Origins of ‘Secondary’ Ice—and Snow

Where does snow come from? This may seem like a simple question to ponder as half the planet emerges from a season of watching whimsical flakes fall from the sky–and shoveling them from driveways. But a new study on how water becomes ice in slightly supercooled Arctic clouds may make you rethink the simplicity of the fluffy stuff. It describes definitive, real-world evidence for “freezing fragmentation” of drizzle as a major source of ice in slightly supercooled clouds. The findings have important implications for forecasting weather and climate.
