They are referred to in the US as Cardinal buoys/Regulatory marks and are used to regulate certain areas. Regulatory buoys are white, with two orange horizontally orange stripes. Between the stripes you'll find either an Orange circle or diamond. The diamond is conveying a warning. It could be a rock, a submerged object, shoal, wreckage or other danger. The black lettering underneath will usually indicate the danger.

Regulatory Buoys.
Mid Channel bouys
A regulator buoy with a diamond symbol indicates a "regulatory" or "information" buoy, which provides information about specific regulations or restrictions in the waterway. The diamond shape typically signifies that there are rules that boaters must follow, such as speed limits, no-wake zones, or areas where certain activities are prohibited. It's important for mariners to pay attention to these buoys to ensure safe and compliant navigation.
Yellow triangles and squares can typically be found on channel buoys and markers to indicate certain information to boaters. Yellow triangles usually indicate caution or danger, such as shoals or rocks, while yellow squares often mark information or regulatory signs, such as speed limits or navigation rules.
A diamond on a regulatory buoy indicates danger or warning. If the diamond is crossed, it indicates any area that you should not enter. It may be a swimming area (which would be a "do not enter" area for boats), rapids, or some other danger. If the diamond is open, it's a warning buoy. It may indicate the presence of a rock, dam, wreck or other danger. Usually, the danger present is indicated under the diamond.
