Audacious grantee @projectceti, led by @davidfgruber, is the largest interspecies communication initiative in history, bringing together more than 50 scientists across eight disciplines with one goal: decode the language of sperm whales.
Using advanced machine learning, state-of-the-art robotics, and underwater acoustics, they’ve done just that, with their discoveries laying the foundation for the first-ever Sperm Whale Language Model.
Hear how their work is reshaping how we understand animal communication and the world around us at the link in bio.

We often judge intelligence by human standards. But what if intelligence is far broader than that? Marine biologist David Gruber says we must look beyond ourselves and learn to appreciate the extraordinary diversity of minds all around us.

Is care the currency of whales? When marine biologist David Gruber (@davidfgruber), Founder and CEO of @projectceti witnessed the birth of a sperm whale, he watched kin and non-kin alike take turns supporting the newborn at the surface for nearly six hours. The encounter would transform his understanding of whale society.
“These creatures, with the largest brains on Earth, have been treated as commodities—hunted for spermaceti oil used in fuel, lubricants, and lipstick—yet they also enact one of the most caring, collaborative entries into the world across all life.”
How do we pay attention to the sea—and how did life begin there? We’re marking Climate Week with new pieces from David Gruber, alongside D. Graham Burnett of @schoolofattention on paying attention to the sea and Jessica Riskin on Lamarck and life’s watery origins.

In 2020, @projectceti led by @davidfgruber became an Audacious grantee with a mission to do the impossible: decode the language of sperm whales.
Using advanced machine learning, state-of-the-art robotics, and underwater acoustics, their team discovered the first-ever phonetic alphabet in a non-human species and identified that sperm whale codas contain spectral properties analogous to vowels in human speech, specifically vowel- and diphthong-like structures. Their discoveries have laid the foundation for the first-ever Sperm Whale Language Model, reshaping how we understand animal communication.
In tandem, CETI has supported youth engagement in marine science in Dominica, helping young people play a vital role in the country’s blue economy through ocean conservation, research, and science communication.
As their Audacious grant comes to a close, it is clear that the impact of their work will go on for generations to come.

The “Save the Whales” movement began with the simple act of listening. And now, we’re on the path toward understanding.
CETI Founder & CEO and National Geographic Explorer @davidfgruber and oceanographer and Explorer at Large @dr.sylviaearle reflect on the immense success of the “Save the Whales” movement, and they embrace the role emerging technologies can play in the future of ocean conservation.
Today, marking Dr. Earle’s birthday, we invite you to join “Her Deepness” and share your message for The Deep Archive at projectceti.org/listen at the link in our bio!

🐋 Whale-Listening is now on the Climate Words lexicon.
"Whale-listening refers to the practice of giving careful attention to whale vocalizations.
The term was introduced by Project CETI (Cetacean Translation Initiative), a nonprofit organization that is applying advanced machine learning and state-of-the-art robotics to listen to and translate the communication of sperm whales.
Through interdisciplinary listening efforts, CETI scientists uncovered that sperm whale language shares key similarities to aspects of human language.
This includes a “sperm whale phonetic alphabet” in which the musical concepts of rubato and ornamentation combine with categorical, context-independent features known as rhythm and tempo or the distinction of their vocalizations in vowels and diphthongs.
Research has also shown how whale voices are socially learned and influence other whale clans, much like human language development ..."

What do you think humans lose by assuming we are the most intelligent species?
Join CETI CEO and Founder and National Geographic Explorer @davidfgruber and oceanographer and Explorer at Large @dr.sylviaearle as they discuss the ancient intelligence that exists in our oceans.

What might whales teach us about coexistence, resilience, family or stewardship?
In a newly published op-ed, @dr.sylviaearle and CETI CEO and Founder @davidfgruber reflect on these questions while sharing a hopeful vision for the future of our oceans—and the role each of us can play in shaping it.

For World Ocean Day, #NatGeoExplorer David Gruber, CEO & Founder of @projectceti, is joined by oceanographer and Explorer at Large Sylvia Earle to dive into the depths of their imagination — into a future where we might understand whales.
Whale songs travel across oceans carrying meaning we have only begun to imagine — stories, memories, cautionary tales, forms of knowledge akin to our own, or far beyond.
An archive is a collection of records preserved because they may matter far beyond the moment in which they were created. The Deep Archive captures a different kind of history: not what humanity knew about whales, but what it longed to understand.
From the wonder of Earle and Gruber to ocean lovers everywhere, we invite you to share your message in celebration of our shared connection to the giants of the deep at projectceti.org/listen. Link in bio.

Brand new episode of Planet Visionaries, in partnership with the @Rolex Perpetual Planet Initiative - I get to chat with marine biologist, explorer and Project CETI (@projectceti) founder David Gruber (@davidfgruber) about how he and a team of researchers are attempting to translate the communication of sperm whales. Pretty neat stuff!!

Marine biologist David Gruber (@davidfgruber) shows how whale song is becoming whale speech. With an underwater recording studio and the largest interspecies communication effort ever attempted, his team at @projectceti is uncovering structures that look less like noise and more like language.
