What is the limitation of deep-sea submersibles contrasted with satellite observation?
Answer
Submersibles offer unparalleled in situ detail of a single location, unlike satellites' global coverage.
The operational strengths of deep-sea submersibles and satellite remote sensing represent a trade-off between depth of detail and breadth of scope. A submersible provides unparalleled in situ (on-site) detail, allowing for intensive study of specific features like a single hydrothermal vent field. However, this method is inherently localized. In contrast, satellite monitoring provides a comprehensive global perspective, covering millions of square kilometers, allowing scientists to track interconnected global processes such as widespread sea level rise or long-term warming trends, which submersibles cannot survey simultaneously.
