In August 2015, around 30 vessels crossed the Great Pacific Garbage Patch in parallel, becoming the largest ocean research expedition ever. Sailing between Hawaii and Los Angeles, the expedition covered 3.5 million square kilometers and collected more data on oceanic plastic than has been collected in the past 40 years combined.

OBJECTIVE

Measuring the amount (total mass), spatial distribution and size distribution of plastic pollution in the Great Pacific Garbage Patch

SURFACE TRAWL

A compact surface trawl was dragged behind each vessel to catch smaller plastic particles. The device, known as a Manta Trawl, is standard scientific equipment used around the world to quantify plastic pollution levels.

SIGHTING APP

A custom-made smartphone app enabled crews to easily count and characterize the large plastic objects floating by.

The Ocean Cleanup Survey App is available for both iOS and Android devices.

Aerial Survey

AERIAL SURVEY

A high-altitude balloon covered a large area to help quantify the rarest but heaviest pieces of debris, such as ghost nets.

MOTHERSHIP

The 171 foot-long Ocean Starr served as the fleet's mothership. It was fitted with two very large nets designed to capture high volumes of all sizes of plastic debris.
