Answer:
The correct answer is:
x. Collect sea surface temperature data
DART buoys (Deep-ocean Assessment and Reporting of Tsunamis) are primarily used for detecting and monitoring tsunamis. They are equipped with sensors to measure changes in sea level, which can indicate the presence of a tsunami wave. DART buoys do not typically take pictures of deep-sea life, measure pH, or perform other functions unrelated to tsunami detection.
Explanation:
DART buoys (Deep-ocean Assessment and Reporting of Tsunamis) are specialized ocean buoys designed to detect and monitor tsunamis in deep ocean waters. They are part of an international tsunami monitoring network operated by organizations such as the National Oceanic and Atmospheric Administration (NOAA).
These buoys are equipped with sensors that measure changes in sea level. Specifically, they use pressure sensors to detect changes in water pressure caused by the passage of tsunami waves. When a tsunami wave passes over a DART buoy, it generates a change in water pressure, which is detected by the sensors. This information is then transmitted via satellite to tsunami warning centers, where it is analyzed to determine the size, location, and potential impact of the tsunami.
DART buoys are typically anchored to the ocean floor at depths ranging from 600 to 6,000 meters (2,000 to 20,000 feet). They consist of a surface buoy and a submerged buoy connected by a cable. The surface buoy contains the necessary electronics for data collection and transmission, while the submerged buoy houses the pressure sensors.
While DART buoys are primarily used for tsunami detection and monitoring, they can also collect other oceanographic data, including sea surface temperature, ocean currents, and wave height. However, their primary function remains the detection and reporting of tsunamis, providing crucial early warning information to coastal communities at risk of tsunami impact.
Final answer:
DART buoys are designed specifically for the detection of tsunamis by measuring sea level pressure changes. Other technologies and projects like the TAO buoys and TOPP use different methods for collecting sea surface temperature and marine ecosystem data. Option Y.
Explanation:
DART buoys, or Deep-ocean Assessment and Reporting of Tsunamis buoys, are crucial instruments used for the detection of tsunamis. They are not used for collecting sea surface temperature data, measuring pH, or taking pictures of deep-sea life. Instead, these buoys measure changes in sea level pressure that might indicate the passage of a tsunami wave. The capability of DART buoys to detect tsunamis in real-time is essential for providing early warnings to potentially affected coastal areas, therefore minimizing damages and saving lives.
For collecting sea surface temperature data, the Tropical Atmosphere Ocean (TAO) array buoys are often utilized, which are equipped with instruments designed specifically for monitoring sea surface temperatures. The use of satellite tags in the Tagging of Pacific Predators (TOPP) project allows for the collection of various data, including temperature, salinity, and depth of the water surrounding marine animals, thereby providing valuable insights into marine ecosystems. Technologies such as multibeam and side scan sonar are also pivotal in oceanographic reconnaissance for mapping the seabed and understanding ocean depths and features.
