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:

Î”h â‰ƒ 3.85d (0.7 – 0.046d)

Where:

Î”h = 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

Î”h â‰ƒ 3.85d (0.7 – 0.046d)

Î”h â‰ƒ 3.85(20) (0.7 – 0.046(20))

That is, Î”h â‰ƒ 77 (0.7 – 0.919)

Î”h â‰ƒ 77 (-0.219)

Î”h â‰ƒ -16.93

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