On the whale trail in the Southern Ocean

It’s vital that we study how climate change is affecting Antarctic wildlife. Tracking whales is one way to find out more

11 October 2023

With sea ice retreating faster than ever in the Antarctic, it’s essential that we find out how this is affecting the wildlife that lives in – and visits – this unique habitat.

Blue, fin, humpback and minke whales depend on the Southern Ocean’s feeding grounds to sustain them. But as the ice disappears, this is affecting the krill that the whales eat.

On a recent expedition to Antarctica, Chris Johnson – WWF’s global lead for whale and dolphin conservation – joined a team of whale ecologists to uncover the secrets of these magnificent marine mammals. 

Studying wildlife in such a remote and inhospitable area can be tricky, but some inspiring tech makes the research much easier.

Navigating inflatable Zodiac boats, researchers skilfully steer around icebergs and use an extended pole to secure suction-cup tags onto the backs of whales.

No bigger than a mobile phone, these non-invasive digital tags capture movement, video recordings and audio samples that give us valuable insights into the whales’ feeding and migratory habits.

Alongside tiny tissue samples and aerial images captured by drones, this vital data will help the team identify priority areas in the Southern Ocean as part of the Protecting Blue Corridors initiative to safeguard the migration routes of these whales.

Your support makes expeditions like this possible, and will help us work towards our goal of establishing a network of marine protected areas in the Antarctic.

Drowning in sound?

Our oceans are alive with an orchestra of marine wildlife. But as the ice melts, the harmony of Arctic seas is being drowned out by human activity. We’re working to understand the impact of this audio intrusion – and how to help combat it
