Autonomous underwater vehicles

Definition

Autonomous underwater vehicles (AUVs) are unmanned, self-propelled robots designed to operate underwater without direct human control. These vehicles are equipped with advanced sensors and navigation systems that allow them to collect data in challenging marine environments, making them essential tools in biogeochemical research for exploring oceanic conditions and processes.

5 Must Know Facts For Your Next Test

1. AUVs can cover large areas of the ocean more efficiently than traditional research vessels, making them invaluable for mapping seabed structures and studying ocean currents.
2. They can be deployed for a variety of applications, such as environmental monitoring, resource exploration, and military surveillance, expanding their utility beyond just biogeochemical research.
3. Many AUVs are designed to operate at different depths, allowing researchers to collect data from surface waters down to the deep sea.
4. Advanced data collection techniques used by AUVs include water sampling, temperature profiling, and nutrient measurement, which are crucial for understanding ocean health.
5. AUVs can be programmed to follow specific routes and collect data autonomously, which significantly reduces the time and cost associated with oceanographic research.

Review Questions
