Is the sea calm and the bottom of the sea rough?

This problem involves knowledge in the fields of ocean and meteorology.

In meteorology, calm weather is usually used to describe weather conditions with no wind or light wind. When the sea surface is calm, the flow field and waves on the ocean surface will be relatively calm.

Seabed roughness has nothing to do with sea surface conditions, but is mainly caused by water movement in geophysical field. There can be turbulent currents in the ocean currents at the bottom of the sea, but this is not directly related to the calm of the sea.

Generally speaking, there is no direct relationship between a calm sea surface and a rough sea floor.
