ENVIRONMENTAL activists in Port Elizabeth are concerned that equipment used to survey the seabed off Algoa Bay for oil and gas could have a detrimental effect on migrating humpback whales.
Lloyd Edwards, whose company Raggy Charters takes tourists on whale-watching excursions, said air cannons which produced a loud noise during the survey were dangerous to marine life.
“The air cannons are pulled by ships and anything that goes within 1km under that ship gets hammered; it gets killed,” Edwards, whose main concern was when the survey was to be conducted, said.
According to Edwards, the date was brought forward from January to this week, because the ships were conveniently in the area and that made it more cost effective to conduct the survey now.
