Final answer:
To transmit data about marine life, satellite tags must be placed on the animals underwater.
These tags collect various data, which is then sent to a satellite and onto scientists, enabling the study of marine ecosystems and the tracking of marine animal behaviors without constant human intervention.
Step-by-step explanation:
In order for the sensor to communicate data about marine life, satellite tags had to be placed underwater in the river.
These tags collect various forms of data, including depth, temperature, and salinity levels, as well as information about the marine animals themselves such as their movement patterns and location.
The data gathered by the tags is sent to a satellite, which then relays it to scientists for research and analysis. This technology is vital in studying marine ecosystems and helping to protect endangered species.
It represents an innovative approach to marine biology research, overcoming the challenges posed by harsh marine environments and the difficulties they present for human operators and machinery.
For instance, the Tagging of Pacific Predators (TOPP) project has utilized such tags to gather valuable insights into the migration patterns of species like elephant seals, white sharks, and bluefin tuna. Moreover, the ability to transmit data to satellites circumvents the need for constant human intervention in such difficult-to-navigate environments.
