How to Calculate and Solve for Geoid Height Anomaly for an Ocean Basin | Gravity

The image above represents geoid height anomaly for an ocean basin. To calculate geoid height anomaly for an ocean basin, one essential parameter is needed and this parameter is depth (d).

The formula for calculating geoid height anomaly for an ocean basin:

Δh ≃ 3.85d (0.7 – 0.046d)

Where:

Δh = Geoid Height Anomaly for an Ocean Basin
d = Depth

Let’s solve an example;
Find the geoid height anomaly for an ocean basin when the depth is 20.

This implies that;

d = depth = 20

Δh ≃ 3.85d (0.7 – 0.046d)
Δh ≃ 3.85(20) (0.7 – 0.046(20))
That is, Δh ≃ 77 (0.7 – 0.919)
Δh ≃ 77 (-0.219)
Δh ≃ -16.93

Therefore, the geoid height anomaly for an ocean basin is -16.93 m.
