Laura Trethewey: Mapping our unknown oceans

Laura Trethewey

This might just be the strangest landscape I’ve featured on the podcast.

It’s a bizarre world of prairie flats larger than the Eurasian Steppe, a 40,000-mile-long underwater mountain range, and an underwater waterfall that makes Angel Falls look small.

Only one quarter of it has been mapped, and less than 1% has been explored with remote vehicles.

Why do we know so little about this vast region of our planet?

And what’s being done to map it?

That’s what we’re talking about today.

I’m joined by Laura Trethewey, an award-winning environmental and ocean journalist, and author of The Deepest Map and The Imperiled Ocean

You can read more about her on her website, and follow her on Twitter.

We spoke about remarkable underwater landscapes, the difficulties of sonar mapping, and the amazing race to map the world’s oceans. 

These are the books we mentioned in the podcast:
