Lesson Express
Q: What are the researchers studying via the submersible?
A: They are observing marine life and measuring the temperature and salinity of the water.
Q: What is most surprising to the researchers?
A: The speed of the change is shocking.
Q: What is the relationship between the melting of the icebergs and rising sea levels?
A: As the ice shelves melt and break apart, they allow water which has been locked up on land as ice for thousands of years to empty into the sea. This pushes sea levels higher.
