Timmy's Journey: Science, the Sea, and a Lost Whale
El Viaje de Timmy: Ciencia, Mar y una Ballena Perdida
A humpback whale named Timmy spent weeks stranded in the Baltic Sea. Fletcher and Octavio dig into why this sea is so dangerous for a whale, how these animals navigate, and what this story tells us about the health of our oceans.
Una ballena jorobada llamada Timmy estuvo varada durante semanas en el Mar Báltico. Fletcher y Octavio exploran por qué este mar es tan peligroso para una ballena, cómo navegan estos animales, y qué nos dice esta historia sobre el estado de nuestros océanos.

Forget geopolitics for a minute.
I want to talk about a whale.
Sí, Timmy.
Yes, Timmy.
Todo el mundo en Alemania habla de Timmy esta semana.
Everyone in Germany is talking about Timmy this week.
So here's what happened.
A humpback whale, which someone named Timmy, got stranded in the Baltic Sea off the German coast.
He's been there for weeks.
And yesterday, officials loaded him onto a barge and started transporting him to the North Sea, where they plan to release him.
The environment minister of Mecklenburg-Vorpommern says Timmy is showing signs of good health.
Es una historia bonita, pero también es una historia de ciencia.
It's a lovely story, but it's also a science story.
Una ballena jorobada en el Mar Báltico es algo muy raro.
A humpback whale in the Baltic Sea is something very unusual.
Casi no pasa nunca.
It almost never happens.
Right, and that's where it gets interesting.
Because the Baltic is not just geographically inconvenient for a humpback whale.
It's physiologically wrong for one.
The water chemistry alone is a serious problem.
Claro.
Right.
El Mar Báltico tiene muy poca sal.
The Baltic Sea has very little salt.
Es casi agua dulce en algunas partes.
It's almost fresh water in some parts.
Las ballenas jorobadas necesitan agua de mar normal, con mucha sal.
Humpback whales need normal sea water, with a lot of salt.
The salinity in the Baltic averages around seven or eight parts per thousand.
The open Atlantic, where humpbacks belong, is closer to thirty-five.
That is a dramatic difference, and it affects everything: how a whale's kidneys function, how it maintains fluid balance, even how sound travels through the water around it.
Y el Mar Báltico también es muy pequeño y poco profundo para una ballena grande.
And the Baltic Sea is also very small and shallow for a large whale.
Las ballenas jorobadas pueden medir quince metros.
Humpback whales can be fifteen meters long.
Necesitan espacio.
They need space.
Fifteen meters, weighing maybe forty tons.
And the Baltic's average depth is only about fifty-five meters.
In some areas, much less.
So this animal was essentially trapped in a bathtub with the wrong kind of water.
Entonces la pregunta es: ¿por qué llegó Timmy al Mar Báltico?
So the question is: why did Timmy end up in the Baltic Sea?
Esto es lo que los científicos quieren entender.
This is what scientists want to understand.
And to answer that, you have to understand how humpbacks navigate.
Because these animals travel extraordinary distances.
They migrate from polar feeding grounds to tropical breeding grounds every year, sometimes ten or twelve thousand kilometers.
They don't do that randomly.
Los científicos creen que las ballenas usan el campo magnético de la Tierra para orientarse.
Scientists believe whales use the Earth's magnetic field to orient themselves.
Es como una brújula natural.
It's like a natural compass.
También usan los sonidos del océano y las corrientes del agua.
They also use ocean sounds and water currents.
Magnetoreception.
The idea that cetaceans have magnetite crystals in their tissue that essentially let them read the Earth's magnetic field like a map.
It's been documented in other animals too, some birds, certain fish.
But in whales, the scale of what that navigation achieves is just staggering.
Pero a veces algo sale mal.
But sometimes something goes wrong.
La ballena pierde la dirección.
The whale loses its way.
Los científicos tienen varias ideas sobre por qué pasa esto.
Scientists have several ideas about why this happens.
Walk me through those.
What are the working theories?
Una teoría es que las tormentas solares cambian el campo magnético de la Tierra temporalmente.
One theory is that solar storms temporarily change the Earth's magnetic field.
Esto puede confundir a la ballena.
This can confuse the whale.
Otra teoría es que el ruido humano en el océano, como los barcos y el sonar militar, interrumpe la navegación.
Another theory is that human noise in the ocean, like ships and military sonar, disrupts navigation.
The underwater noise pollution angle is one I find genuinely troubling.
The ocean is not quiet anymore.
Commercial shipping, seismic surveys for oil and gas, military sonar exercises.
The North Sea and the approaches to the Baltic are among the busiest shipping corridors in the world.
That acoustic environment is completely different from what humpbacks evolved in.
Sí, y hay otra posibilidad también.
Yes, and there's another possibility too.
Timmy era joven, probablemente.
Timmy was probably young.
Los animales jóvenes cometen más errores de navegación.
Young animals make more navigation errors.
No tienen tanta experiencia como los adultos.
They don't have as much experience as adults.
Which makes you wonder how many young whales make exactly this mistake and don't survive it.
Timmy had the luck of getting noticed, getting named, getting a rescue operation mobilized on his behalf.
Exactamente.
Exactly.
Y esto me parece importante.
And this seems important to me.
Las ballenas jorobadas casi desaparecieron en el siglo veinte.
Humpback whales almost disappeared in the twentieth century.
Los cazadores de ballenas mataron a miles y miles de ellas.
Whale hunters killed thousands and thousands of them.
The numbers are almost incomprehensible.
In the twentieth century alone, whalers killed something like two hundred thousand humpbacks in the Southern Hemisphere.
By the 1960s, the global population had collapsed to perhaps a few thousand animals.
The species was genuinely on the edge.
Pero después vinieron las leyes de protección.
But then the protection laws came.
La Comisión Ballenera Internacional prohibió la caza comercial de ballenas jorobadas en 1966.
The International Whaling Commission banned commercial hunting of humpback whales in 1966.
Y la población empezó a recuperarse lentamente.
And the population began to recover slowly.
One of conservation's genuine success stories, actually.
Current estimates put the global humpback population at around eighty to ninety thousand.
Still well below pre-whaling numbers, but the trajectory is encouraging.
The North Atlantic population in particular has bounced back considerably.
Y porque hay más ballenas ahora, vemos más situaciones como Timmy.
And because there are more whales now, we see more situations like Timmy's.
Más ballenas en el océano significa más posibilidades de que una ballena tome el camino equivocado.
More whales in the ocean means more chances for a whale to take the wrong path.
That's a counterintuitive point and I think it's right.
A recovering population moving back into areas it was absent from for decades, re-encountering coastlines and shallow seas, before accumulated generations of navigational knowledge can catch up.
También hay que pensar en el cambio climático.
You also have to think about climate change.
Los peces que comen las ballenas se mueven porque el agua está más caliente.
The fish that whales eat are moving because the water is warmer.
Y las ballenas siguen a los peces.
And whales follow the fish.
A veces esto las lleva a lugares nuevos y peligrosos.
Sometimes this takes them to new and dangerous places.
The prey-following hypothesis.
Krill and small fish populations are genuinely shifting poleward as sea temperatures rise.
And if a humpback follows a food source far enough into the North Sea and then loses its bearings, the entrance to the Baltic is right there.
The Skagerrak, the Kattegat, and suddenly you're committed to a very wrong turn.
Y entonces la operación de rescate.
And then the rescue operation.
¿Cómo se mueve una ballena de cuarenta toneladas?
How do you move a forty-ton whale?
Esto también es ciencia.
This is also science.
This part I genuinely wanted to understand.
Because you can't just attach a rope and tow.
The stress alone could kill the animal.
Los expertos usaron una técnica especial.
The experts used a special technique.
Construyeron una plataforma flotante, casi como una piscina grande en el agua.
They built a floating platform, almost like a large pool in the water.
La ballena nadó adentro, y después cerraron la plataforma y la pusieron en la barcaza.
The whale swam inside, and then they closed the platform and put it on the barge.
Es un proceso muy lento y cuidadoso.
It's a very slow and careful process.
And during transport, they have to keep the animal wet, monitor its breathing and heart rate, and manage the stress response.
Cortisol levels in a distressed whale can spike dangerously.
There's a whole field of marine mammal medicine built around these interventions, and a lot of what they know came from hard experience with strandings that didn't go well.
Alemania hizo todo esto públicamente.
Germany did all of this publicly.
Había cámaras, periodistas, mucha gente en la costa mirando a Timmy.
There were cameras, journalists, many people on the coast watching Timmy.
Se convirtió en una especie de símbolo nacional.
He became a kind of national symbol.
The naming does something psychologically, doesn't it.
A whale called Timmy is a different kind of story than 'a cetacean, approximately forty metric tons.' People followed his health updates.
There were crowds on the shore.
And that collective attention probably helped keep the political will to fund the rescue operation.
Sí.
Yes.
Y hay algo más importante.
And there's something more important.
Cuando los científicos estudiaron a Timmy en el Mar Báltico, aprendieron muchas cosas sobre la salud de las ballenas y sobre los problemas del océano.
When scientists studied Timmy in the Baltic Sea, they learned many things about whale health and about the problems of the ocean.
La ballena fue como una ventana al mar.
The whale was like a window into the sea.
Whales as ocean health indicators.
Marine biologists talk about this a lot.
Because these animals sit at the top of the food chain and migrate across entire ocean basins, their condition, their behavior, their strandings, they're all signals about what's happening at the system level.
You can read the ocean through a whale.
Y el Mar Báltico necesita toda la atención posible.
And the Baltic Sea needs all the attention it can get.
Tiene muchos problemas: contaminación, poco oxígeno en el agua, y los efectos del cambio climático.
It has many problems: pollution, low oxygen in the water, and the effects of climate change.
Es uno de los mares más afectados de Europa.
It is one of the most affected seas in Europe.
Dead zones.
The Baltic has some of the worst hypoxic dead zones in the world, areas where agricultural runoff has driven such extreme algae blooms that the oxygen is stripped out of the water completely.
Nothing lives there.
And those zones have been expanding for decades.
A humpback whale stumbles into that water and you get a sense of how degraded the environment actually is.
Por eso la historia de Timmy es más que una historia bonita de un animal.
That's why Timmy's story is more than a nice story about an animal.
Es una historia sobre los océanos, sobre el clima, y sobre lo que los humanos hacemos al mar.
It's a story about the oceans, about the climate, and about what humans do to the sea.
And hopefully, a story that ends reasonably well.
The barge has departed.
The North Sea is maybe two or three days away.
If the release goes to plan, Timmy swims free in water where he can actually survive.
Whether he finds his migration route again, whether he ends up eventually in the North Atlantic feeding grounds, that part nobody knows.
Oye, Fletcher, antes de terminar.
Hey, Fletcher, before we finish.
Usé una expresión antes que quiero explicar.
I used an expression earlier that I want to explain.
Dije que Timmy 'tomó el camino equivocado'.
I said Timmy 'took the wrong path'.
En español también decimos eso, 'tomar el camino equivocado', pero también tenemos otra expresión muy común: 'perder el norte'.
In Spanish we also say that, 'take the wrong path', but we also have another very common expression: 'to lose the north'.
Perder el norte.
Lose the north.
I like that.
Is it used the same way we'd say 'lose your bearings' in English, or is there a different flavor to it?
Es muy similar, pero también significa que alguien perdió la claridad mental, que está un poco loco o confundido.
It's very similar, but it also means that someone has lost mental clarity, that they're a bit crazy or confused.
Puedes decir 'este político perdió el norte' y significa que ya no piensa con lógica.
You can say 'this politician has lost the north' and it means they no longer think logically.
No es solo dirección física.
It's not just physical direction.
So Timmy, the whale who literally lost the north, is also a walking metaphor for half the politicians we cover on this show.
I didn't plan that, but I'll take it.
Exacto.
Exactly.
Y si alguna vez te pierdes en Madrid, Fletcher, puedes decir 'perdí el norte'.
And if you ever get lost in Madrid, Fletcher, you can say 'I lost the north'.
La gente va a entender perfectamente.
People will understand perfectly.
That one I can actually use without accidentally telling anyone I'm pregnant.
Safe waters.
Appropriate for a whale episode.
