Satellite gravimetry
Satellite gravimetry involves using satellites to measure variations in Earth's gravity field. These measurements reveal how mass is distributed within the planet, helping scientists detect changes such as the movement of water, ice, or underground minerals. By analyzing tiny differences in gravity from space, researchers gain insights into natural phenomena like ice sheet melting, groundwater depletion, and volcanic activity. This technique provides a global perspective that ground-based methods can't easily achieve, making it a valuable tool for monitoring Earth's dynamic processes and supporting environmental and resource management efforts.
