Count seals in Antarctica from the comfort of your couch

The video tutorial introduces Weddell seals, highlighting their significance as an iconic Antarctic species. It explains the Satellites Over Seals (SOS) citizen science project, which involves counting seals using satellite images to understand their population and the impact of fishing in the Ross Sea. The tutorial emphasizes the importance of Weddell seals as an indicator species and engages viewers in a seal-counting activity.

What is a unique characteristic of Weddell seals?

• They are found in tropical regions.

• They are perfectly adapted to harsh conditions.

• They can live up to 50 years.

• They are the northernmost mammal in the world.

What is the main goal of the 'Satellites Over Seals' project?

• To study the diet of Weddell seals.

• To conduct a comprehensive count of Weddell seals.

• To relocate Weddell seals to safer areas.

• To track the migration patterns of Weddell seals.

Why are Weddell seals considered an indicator species?

• They prey on Antarctic toothfish, which are affected by fishing.

• They are immune to climate change effects.

• They have no natural predators.

What has increased in the Ross Sea over the last 20 years?

• Tourism activities.

• Ice melting rate.

• Commercial fishing for Antarctic toothfish.

• Seals' population.

How do scientists hope to use satellite imagery in their research?
