Understanding Gravitational Effects

The video explains that sea levels vary in different locations due to factors beyond tides, such as salinity and density differences. It highlights the discovery of lunar gravitational irregularities affecting moon landings, leading to mapping efforts. Similarly, Earth's uneven gravity impacts sea levels and currents, prompting precise mapping to track climate change. The GOCE satellite mission is introduced, which maps Earth's gravity with high precision to understand its effects on ocean currents.

Describe the role of the Gravity Field and Steady State Ocean Circulation Explorer (GOCE) in studying ocean currents.

What technological features does the GOCE satellite utilize to maintain its orbit?
