Exploration, whales and citizen science

What is the objective of Happywhale ?

Happywhale is a research collaboration and citizen science platform focusing on whales. It lets anyone contribute to improving our understanding of these fascinating animals.

It’s easy to use: anyone who spots a whale in the wild can take a photo of it and upload it, providing us with when and where the photo was taken. Our image recognition tools (based on artificial intelligence) are then able to identify the individual photographed. This contributes to our scientific database. And we notify the contributor if this whale is resighted. This means they can follow the journey of THEIR whale and understand its migration.

Our tools currently apply to humpback whales and sperm whales, and we hope to expand to other species in the near future.

How do you identify a whale?

First, we look for the ‘blow’ — when a whale exhales — then we look for the body shape, dorsal fin, and what behaviours are displayed. Through many years of experience, we can usually identify the species of whale very quickly, but there are also good identification books that are very useful, such as Handbook of Whales, Dolphins, and Porpoises of the World by Mark Carwardine.

What is the purpose of all these observations?

They help us better understand whales and their place in the marine ecosystem. For example, before most whales were killed by 20th-century industrial whaling, we believe that whales in Antarctic waters ate massive amounts of krill. Logically, you’d think that reducing whale populations should increase krill volumes in the region. What is remarkable, though, is that when these whales were removed, it appears that the total volume of krill decreased. This is a paradox, but what we now know is that whales actually fertilise the oceans by recycling nutrients.

This discovery is extremely important for our understanding of ocean health, nutrient cycling and even the global carbon balance. Whales literally help control the global climate! 

Are the data collected on board analysed afterwards?

Absolutely. That’s the whole point. Science is not a moment of discovery; it is a long term building of understanding. What’s more, the passengers gave us a warm welcome and showed strong interest in our research. These explorations can have a profound and lasting impact on travellers.

Passenger cruise ships cannot do everything a dedicated science vessel can do. But they can help research by providing platforms that are useful to scientists and educational for the public. These education and science opportunities must be seized to their fullest.

PONANT want to make the Commandant Charcot available to scientists studying the polar regions. I see great potential here and am excited to be a part of helping PONANT create the most impactful science opportunities possible with the unusual itineraries in the Arctic and Antarctica that the Commandant Charcot will sail. Especially since it fits perfectly with Happywhale’s purpose: supporting scientific discovery and sharing it with the public.

Do these types of collaborative tools raise awareness of environmental issues?

Of course. Citizen science is powerful both because it can be a source of data for research and because participating in science makes it more meaningful to the public. Reading an article about events happening on the other side of the planet might teach you a little, but it doesn’t help you understand what you can do to preserve the environment. If you participate in it first-hand — if you photograph a whale, then learn that your whale is new to science, then are notified that your whale has been seen again thousands of miles away — it means a great deal more.
