Abstract

Environmental Science and Management

Noosa Main Beach (Sunshine Coast, Australia) experienced large accumulations of the filamentous algae Hincksia sordida during the summer months for three consecutive years. Visually unappealing and producing an obnoxious odour, it had a significant negative impact on the local tourist-based economy. Traditional methods of dealing with the algae were unsuccessful and alternative options were generated. During investigations it was revealed that seaward of the surf zone the algae is present as a thin cloud of algae close to the seabed. A seabed-based algae curtain was proposed to prevent movement of the algae into the bathing reserve. A trial was fabricated to evaluate its effectiveness; however installation was delayed due to the complete absence of the algae at Noosa for over three years. In 2009 a trial deployment was undertaken as a proactive step to ensure rapid deployment in the event of the algae returning. While its success in mitigating the presence of the algae could not be evaluated, the curtain successfully withstood the impact of Tropical Cyclone Hamish with little damage and performed well in a range of wave conditions.
