A Microscopic Tour Through A Norwegian Fjord

The video explores the hidden world of microbes in fjords, highlighting the challenges faced in discovering them and the role of microscopy in making them visible. It delves into the different zones of fjords, from the sunlight to the midnight zone, and the unique organisms found in each. The video also discusses the abundance of nematodes and their significance in microbial ecosystems. Finally, it addresses the impact of climate change on these ecosystems and the importance of understanding microbial adaptation.

What has allowed us to explore the hidden world of microbes?

• Advanced computer algorithms

• Genetic engineering

• Satellite imaging

• The invention of the microscope

What was the initial unexpected finding in the sediment samples from the fjord?

• Exotic fish species

• A large number of jellyfish

• Barren samples with few organisms

• High levels of pollution

Which zone in the fjord is ideal for photosynthetic organisms?

• The twilight zone

• The abyssal zone

• The midnight zone

• The sunlight zone

What is a unique feature of the nematodes found in the deeper parts of the sea?

• They are bioluminescent

• They can survive without oxygen

• They glow in the dark

• They have structures resembling oil deposits

What role do microbes play in the fjord ecosystem?

• They are primary predators

• They are the main producers of oxygen

• They form the base of the food chain for large mammals

• They cycle elements like carbon and sulfur

How might climate change affect microbial communities in fjords?

• By decreasing water temperatures

• By altering water circulation and nutrient availability

• By increasing the number of predators

• By increasing the salinity of the water

Why is it important to study microbial communities in fjords?

• To understand their role in the ecosystem and adaptation to changes

• To find new sources of food

• To develop new medicines

• To increase tourism in fjord regions
