The image above represents genoid height anomaly for an ocean basin.

To compute for genoid height anomaly for an ocean basin, one essential parameter is needed and this parameter is **depth (d).**

The formula for calculating genoid 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 genoid 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))

Δh ≃ 77 (0.7 – 0.919)

Δh ≃ 77 (-0.219)

Δh ≃ -16.93

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