An assessment of floating marine debris within the breakwaters of the University of the South Pacific, Marine Studies Campus at Laucala Bay

Abstract

Contributions of Pacific Islands countries to marine plastic debris are disproportionate to the effects on people's connections to the ocean. Plastic waste management initiatives face challenges in containing waste and consequently plastics plague coastal environments. The Seabin, a floating trash skimmer, presents a novel and replicable approach to collecting and cataloguing marine plastics. The objectives of the study were to conduct an audit of marine plastic debris within the breakwaters of the University of the South Pacific, Marine Campus at Laucala Bay while simultaneously gauging the effectiveness of the Seabin and providing recommendations to enhance its utility. Inorganic debris was comprised entirely of plastics while the majority of debris collected was organic. This study provides the first assessment of floating marine plastic debris in an inshore environment of a Pacific Island country. Plastic debris assessments have the potential to inform policy and pivot management efforts to mitigate plastic waste pollution.
