Question 22

The table below shows the surface area and estimated annual volume loss of seven selected glaciers in the Southern Alps of New Zealand.

Glacier	Surface Area ( $km^2$ )	Annual Volume Loss ( $m3/year10^6\text{ m}^3/\text{year}$ )
Tasman Glacier	101.2	5.3
Murchison Glacier	18.2	2.1
Mueller Glacier	12.1	1.4
Hooker Glacier	11.0	1.2
Fox Glacier	30.2	2.4
Franz Josef Glacier	34.5	1.8
Classen Glacier	15.0	1.2

Calculate the mean annual volume loss for these glaciers from the data shown. You must show your working.
