In this episode of Ocean Explained, we meet Cécile Gaspar, a veterinary surgeon, marine ecologist, and founder of Te Mana o te Moana, one of French Polynesia’s leading marine conservation organizations. From the Turtle Clinic on Tetiaroa to high-stakes sea turtle rescues, Cécile shares what it takes to treat, rehabilitate, and release injured marine turtles back into the wild.

Attend the daily reality of emergency veterinary care in the Pacific, the emotional weight of saving endangered animals, and the science behind long-term green turtle monitoring, including more than 8,000 nesting traces recorded since 2007. This conversation also dives into the story of Te Mana o te Moana, its mission to protect marine life, and its education programs that have reached more than 140,000 schoolchildren.

Cécile reflects on her path from veterinary medicine to marine ecology, the early days of conservation in French Polynesia, her work with Tetiaroa Society and the World Ocean Network, and the deeper meaning behind “Te Mana o te Moana,” the spirit of the ocean.

We also discuss of course sea turtles but also coconut crabs, climate change, marine research, life on Tetiaroa, and Cécile’s unforgettable encounter with Moon-landing astronauts visiting French Polynesia.https://www.temanaotemoana.org/

Why do hundreds of lobsters march single-file across the seafloor like a living conga line? Are lobsters really immortal? What are the odds of pulling a 1-in-30-million golden (yellow) lobster — or a 1-in-2-million blue one out of the sea?

In this episode of Tide Talk, we dive into the strange, surprisingly sophisticated world of lobsters: their biology, their colors, the myths around their lifespan, and what climate change is doing to the most valuable single-species fishery in North America.

We unpack lobster biology 101 (anatomy, antennae, the two-claw toolkit, nocturnal habits, and the brutal moulting cycle), the genetics behind rare blue and yellow color morphs and why camouflage is the norm, the 50,000-egg gamble of reproduction (including two-year sperm storage and the tiny number of larvae that reach adulthood), the immortality myth through telomerase and telomeres and why “no cellular aging” is not the same as “cannot die,” the real causes of lobster death (predation, shell disease, moulting exhaustion, and cannibalism), the Caribbean spiny lobster (Panulirus argus) conga line as an autumn-storm evacuation with S-shaped lines of ~50, drag reduction up to 50%, and defensive rosette formation, and finally the climate and fisheries stakes, from record catches in the Gulf of Maine to collapses in southern New England, rising disease, range-expanding predators, and falling recruitment — one species, a full biology lesson, and a real-time climate story.

That was Tide Talk. Same tide, next time.

Dive into the unexpected acoustic world of the deep ocean in this illuminating episode of Tide Talk. While most imagine the deep sea as a silent, dark void, we reveal the surprising truth: it's a bustling concert hall of natural and man-made sounds.

Discover the tiny pistol shrimp that produces sounds louder than jet engines, the haunting songs of deep-diving whales, and the geological symphony of underwater earthquakes and melting icebergs. We also examine how human activities create an artificial cacophony that disrupts this ancient soundscape.

From the crackling colonies of snapping shrimp to the mysterious unexplained booms that baffle scientists, this episode will forever change how you imagine the ocean depths. Perhaps the deep sea isn't so quiet after all—you just need to know how to listen.

For those who thought silence ruled the abyss, prepare to have your assumptions depth-charged. The ocean, it turns out, never stops talking.

Tune in!
