The kernel density estimation of body mass by species and island

This sonification sequence consists of 5 parts.

The first stream has the following sound mappings.

The Body Mass value is mapped to time. The duration of the stream is 3 seconds

The Body Mass value is mapped to pan. The domains values from 2500 to 6500 are mapped to

The Kernel density is mapped to pitch. The domains values from 1.654e-30 to 0.001057 are mapped to
