A scientific experiment hopes to restore vital nutrients to the ocean by using fake excrement that would once have been produced by the endangered mammal

In a few weeks an international group of scientists will launch an unusual marine research project. They will dust the surface of the Indian Ocean with artificial whale faeces.

The aim of this excremental experiment is straightforward. It is to determine if it is possible to reboot marine ecosystems that have been starved of nutrients and in the process restore dwindling fish populations. It is also hoped the project will help in the battle against the climate crisis.
