A noise-making protest of oil and natural gas exploration offshore didn’t make much noise at all today.

The whistle-blowing demonstration at noon at Marion Square wasn’t loud enough to drown out traffic at the nearby King and Calhoun streets intersection.

But Katie Parrish, of Oceana, said the point was made by the fact that the city of Charleston wouldn’t permit the air horn protest she planned because it was too loud.

Environmental groups oppose the use of seismic guns to search for oil and natural gas offshore because the loudness would deafen and disorient sea creatures such as whales and dolphins. The guns would be far louder than the air horns.
