What other technology has expanded under water research?

Underwater research has significantly advanced with the development of autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs). These technologies enable scientists to explore deep-sea environments with minimal human intervention, providing high-resolution imaging and data collection capabilities. Additionally, advancements in sonar and environmental sensors have enhanced the ability to map ocean floor topography and monitor marine life, leading to more comprehensive understanding of underwater ecosystems.
