Tides and Currents in the Mariana Trench: Present but Subdued by Extreme Depth

Tides

• Tidal Range: Small (few meters) due to depth and distance from land.
• Tidal Forces: Influenced by Earth's rotation, moon/sun gravity, but dampened by depth.

Currents

• Deep Ocean Currents: Part of global circulation, driven by temperature/salinity, wind, rotation.
• Internal Waves: Density-driven waves traveling long distances.
• Trench-Related Currents: Localized downwelling/upwelling along slopes.

Overall, tides and currents exist but are less pronounced than in shallower waters.
