Ocean exploration provides the data, information, and tools needed to increase our understanding of ocean processes and ecosystems. Modern marine technologies allow us to explore the ocean in increasingly systematic, scientific, and noninvasive ways. Ships act as floating research platforms during expeditions, carrying crew, supplies, and equipment to poorly understood regions far from shore. Underwater robots, such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), help study areas of the ocean that are inaccessible to humans. Vessels and robots are also equipped with specialized exploration tools, ranging from sonar technologies, sensors, specimen collectors, and high-definition cameras capable of collecting data in the cold, dark, depths of the ocean. Learn more about the variety of marine technologies used to explore the ocean and practice using the engineering design process to develop your own tools to help better understand our ocean.
