underwater gliders

Underwater gliders are autonomous robotic vehicles designed to explore the ocean. They move by altering their buoyancy—sometimes becoming slightly heavier or lighter—to glide smoothly through the water without needing engines. Equipped with sensors, they collect data on temperature, salinity, currents, and other ocean conditions as they traverse long distances. Their efficient, energy-saving design allows for extended missions, making them valuable for scientific research, environmental monitoring, and underwater mapping. Essentially, underwater gliders are like smart, energy-efficient submarines that gather crucial ocean information over weeks or months.
