Question

The diagram shows organisms a diver observed during an ocean dive.

A sailboat floats on the water with objects below it in the water. These objects are labeled seaweed negative 20 meters, clownfish negative 23 meters, squid negative 44 meters.
What did the diver most likely use as a reference point to describe the position of the squid?

the ocean surface
the ocean floor
the position of the clownfish
the position of the seaweed

Answer 1

the ocean surface

Negative depths (e.g., −44 m) indicate distance below the water’s surface, which is used as the reference point.
