Race For Water Odyssey: Quantitative and Qualitative Assessment of Marine Plastic Debris Collected on Shorelines
With the help of the local people we met during the course of the 2015 Odyssey, the main objective, obtaining a collection of comparable data about marine plastic pollution using the NOAA internationally recognized protocol, has been achieved. It cannot be sufficiently stressed that not one of the 3...

With the help of the local people we met during the course of the 2015 Odyssey, the main objective, obtaining a collection of comparable data about marine plastic pollution using the NOAA internationally recognized protocol, has been achieved. It cannot be sufficiently stressed that not one of the 30 sampled shorelines during this worldwide journey was free from marine plastic debris. As for the recent identification of plastic debris in the Arctic and Antarctic areas, this observation confirms that plastic contamination in the oceans is ubiquitous. Whether in terms of macrodebris (>2.5 cm) or microplastics (< 5 mm) concentrations, Hawaii constitutes by far the 2015 Odyssey’s most notable hotspot.
