Saguenay–St.Lawrence Marine Park

Water Column

Illustration of the water column with 18 specimens living in the Saguenay - St. Lawrence. The water column is divided into three sections: upper layer, intermediate layer and bottom layer.

The Water Column

To have a better understanding of the water column, simply imagine a long tube-like cylinder passing through a body of water from top to bottom. We have grouped together specimens of the living creatures belonging to each layer of this marine ecosystem.

You are now going to discover the water column of the Saguenay–St. Lawrence Marine Park. But don’t dive in without your mission.

Mission

Explore the layer that has been assigned to you and choose one or two specimens.

In your Science Log, answer the questions about the specimen(s) you have chosen.
