Abstract: Abstract
Marine debris is one of the most significant issues facing oceans
worldwide. The sources of this debris vary depending on proximity to
urban centres and the nature of activities within an area. This paper
examines the influence of tourism in the southern Great Barrier Reef
(GBR), and its contribution to litter levels in the region. By
conducting beach debris surveys on occupied and unoccupied islands, this
study found that debris was prevalent throughout the region with
significant differences in material types between locations. The
greatest source of debris from publically accessible islands was
tourist-related, with this source also influencing debris loads on
nearby uninhabited islands. A focus on debris at Heron Island, showed
that sites close to amenities had greater levels of tourist-sourced
items like cigarette butts. These findings indicate the contribution of
tourists to this problem and that working with operators and managers is
needed to minimise visitor impacts.

(http://www.sciencedirect.com/science/article/pii/S0025326X1400191X) Abstract: Pearl oyster aquaculture is a major activity in French Polynesia atoll lagoons. After the economic decline that characterized the last decade, concerns recently rose about discarded installations and materials that supported aquaculture practices and by facilities abandoned after they had to close their activities. In May 2013, a first inventory of the type and amount of pearl farms derelict gear (PFDG) was achieved on 47 sites in Ahe lagoon. Surveys were conducted within and outside the boundaries of aquaculture concessions. Twenty types of PFDG littered the lagoon floor and the water column. The most impacted areas were near abandoned grafting houses with up to nine types of PFDG. Forty-five percent of the sites were impacted, including outside concessions. While management authorities are fully aware of the problem, this first assessment is a wake-up call to stimulate the cleaning of lagoons, enhance awareness among farmers, and identify potential ecological consequences on lagoon ecosystems.

(http://www.sciencedirect.com/science/article/pii/S0025326X14001490) Abstract: Composition and abundance of persistent buoyant litter (plastics, polystyrene and manufactured wood) were investigated at riversides and on adjacent coastal beaches of four rivers flowing into the SE Pacific Ocean. Persistent buoyant litter made up the main share of litter at riversides (36?82%) and on coastal beaches near the river mouths (67?86%). The characteristic litter composition of each river is attributable to human influences along its course. Riverine litter items were deposited to both sides of the river mouths on coastal beaches, and their abundance generally declined with distance from the river mouth. However, maximum litter accumulations were often found on beaches north of the river mouth, suggesting a long-term influence of the prevailing equatorward low-level jet along the Chilean coast. The results confirm that riverine transport has an important impact on litter abundances on coastal beaches.

Technol., Just Accepted Manuscript DOI: 10.1021/es4053076 Publication Date (Web): April 7, 2014 Abstract We present an extensive survey of floating plastic debris in the eastern North and South Pacific Oceans from more than 2,500 plankton net tows conducted between 2001 and 2012. From these data we defined an accumulation zone (25 to 41°N, 130 to 180°W) in the North Pacific subtropical gyre that closely corresponds to centers of accumulation resulting from the convergence of ocean surface currents predicted by several oceanographic numerical models. Maximum plastic concentrations from individual surface net tows exceeded 106 pieces km-2, with concentrations decreasing with increasing distance from the predicted center of accumulation. Outside the North Pacific subtropical gyre the median plastic concentration was 0 pieces km-2. We were unable to detect a robust temporal trend in the dataset, perhaps because of confounded spatial and temporal variability. Large spatio-temporal variability in plastic concentration causes order of magnitude differences in summary statistics calculated over short time periods or in limited geographic areas. Utilizing all available plankton net data collected in the eastern Pacific Ocean (17.4°S to 61.0°N; 85.0 to 180.0°W) since 1999, we estimated a minimum of 21,290 metric tons of floating microplastic. http://pubs.acs.org/toc/esthag/0/ja
