Hello, I'm Dashiani Navanayagam and welcome to the conversation from the BBC World Service.
This is the programme which delves into the work and experiences of women doing incredible things around the world.
Now, traditionally ecologists have measured environmental health by looking at habitats.
However,
that's now changing as eco-acoustic approaches are increasingly being used as a tool to monitor the health of ecosystems.
My guests today are two women who know the importance of what sound can tell us about our natural world.
and our own impact on it.
Dr Denise Rich is a German marine mammal ecologist and senior lecturer at the Scottish Association for Marine Science who's been studying aquatic soundscapes for over 20 years.
And Dr Elizabeth Snidersick is an Australian ecologist who monitors the sound of secretive wetland birds and is researching how sound itself can be used as a restoration tool.
We'll find out more shortly, but first Elizabeth and Denise, welcome to the conversation.
Thank you very much.
Nice to be here.
It's fabulous to be here, Dushy.
Thank you.
Denise,
let's start with you
because the vast open ocean can appear very deadly quiet compared to many places on land.
But actually, how true is that?
Not true at all, to be honest.
