Yes and no - all modern military submarines have special forward-looking and top-sounding under-ice Sonar systems that not only detect ice, but can give the approximate thickness of the ice as well.
The forward-looking under-ice system scans at a much higher frequency and is separate from the main sonar array. The top-sounding system is essentially a reverse fathometer, giving the distance from the boat to the ice surface as well as the ice thickness. Ice thickness is essential to know in situations where surfacing through the ice is required.
As for open water icebergs, the noise created by the water movement against the iceberg can be detected by passive sonar, and of course detected by active sonar, though active is rarely, if ever, used.
It should be noted that large icebergs that are big enough to be a navigation hazard are monitored and tracked by major nations, and that information is made available to all military and commercial vessels. Large-mass icebergs in the open ocean are more of a hazard to submarines than surface vessels since their depth and mass below the water is generally a lot more than what is seen above the waterline.

Can you give an example of SONAR?
A sonar is Fitted into a ship to detect how deep the water is
What is the difference between Sonar and Ultrasound?
sonar is used to detect big penises
What is the system that uses the reflection of underwater sound waves to detect objects?
sonar(sound navigation and ranging)
What is the device called to detect animal sounds?
Sonar
What instrument do we use to detect sound waves?
Sonar
Can sonar detect any object?
Sonar can generally detect most things, and is commonly used in aviation An example of something that it cannot detect is the Stealth Fighter and the Stealth Bomber. They both have paint that helps deflect sonar rays, and the Fighter has very rigid edges that makes it almost undetectable.
What is a sub spotter called?
A sub spotter is typically called a Submarine Sonar Technician or Sonar Operator. Their role is to detect and locate enemy submarines using sonar technology.
What is one event where sonar was used in World War 2?
Sonar was used to detect and hunt submarines in WW2
What are radio waves called to detect subs called?
Sonar.
Can sonar use in periscope depth?
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
What is a sonar used for?
Sonar is used to detect other vessels or ships/submarines through a tube-like device> Andrea
