Trash-mapping expedition sheds light on 'Great Pacific Garbage Patch' Trash-mapping expedition sheds light on 'Great Pacific Garbage Patch'

Scientists and volunteers who have spent the last month gathering data on how much plastic garbage is floating in the Pacific Ocean returned to San Francisco on Sunday and said most of the trash they found is in medium to large-sized pieces, as opposed to tiny ones.Scientists and volunteers who have spent the last month gathering data on how much plastic garbage is floating in the Pacific Ocean returned to San Francisco on Sunday and said most of the trash they found is in medium to large-sized pieces, as opposed to tiny ones.
Volunteer crews on 30 boats have been measuring the size and mapping the location of tons of plastic waste floating between the west coast and Hawaii that according to some estimates covers an area twice the size of Texas.Volunteer crews on 30 boats have been measuring the size and mapping the location of tons of plastic waste floating between the west coast and Hawaii that according to some estimates covers an area twice the size of Texas.

“It was a good illustration of why it is such an urgent thing to clean up, because if we don’t clean it up soon, then we’ll give the big plastic time to break into smaller and smaller pieces,” said Boyan Slat, who has developed a technology he says could start removing the garbage by 2020.“It was a good illustration of why it is such an urgent thing to clean up, because if we don’t clean it up soon, then we’ll give the big plastic time to break into smaller and smaller pieces,” said Boyan Slat, who has developed a technology he says could start removing the garbage by 2020.
A 171ft mother ship carrying fishing nets, buckets, buoys and bottles, among other items, and two sailing boats with volunteers who helped collect the garbage samples arrived at San Francisco’s Piers 30-32. The boats went on a 30-day voyage as part of the “Mega Expedition”, a major step in an effort to clean up what is known as the Great Pacific Garbage Patch.A 171ft mother ship carrying fishing nets, buckets, buoys and bottles, among other items, and two sailing boats with volunteers who helped collect the garbage samples arrived at San Francisco’s Piers 30-32.

Slat said the group would publish a report of its findings by mid-2016 and after that hoped to test out a one-mile barrier to collect garbage near Japan. The ultimate goal is the construction of a 60-mile barrier in the middle of the Pacific.

“I was diving in Greece and realised that there were more plastic bags than fish,” he said, “and I wondered: why can’t we clean this up?”“I was diving in Greece and realised that there were more plastic bags than fish,” he said, “and I wondered: why can’t we clean this up?”
After dropping out of university after six months, Slat dedicated his life to developing the technology the group will start testing next year. He has envisioned using long-distance floating barriers that will attach to the seabed and target swirling ocean currents full of waste to skim garbage from the surface while aquatic life and currents pass underneath.After dropping out of university after six months, Slat dedicated his life to developing the technology the group will start testing next year.

After a 2012 Ted Talk about his idea was viewed more than 2m times, Slat decided to launch a Kickstarter campaign and raised $2.27m, helping to start his organisation. Soon, his innovative solution got the attention of major philanthropists in Europe and Silicon Valley, including Salesforce.com chief executive Marc Benioff, who are helping pay for the data-gathering efforts and the technology’s development.After a 2012 Ted Talk about his idea was viewed more than 2m times, Slat decided to launch a Kickstarter campaign and raised $2.27m, helping to start his organisation.

The Pacific expedition, which will end in mid-September, will gather data more extensive than what has been collected in the past 40 years. It also will give a better estimate of the how much plastic waste is in the Pacific, Slat said.The Pacific expedition, which will end in mid-September, will gather data more extensive than what has been collected in the past 40 years.

The boaters are using GPS and a smartphone app to search for and record the plastic. They take samples and ship them to the Netherlands, where the plastics are counted and recorded.The boaters are using GPS and a smartphone app to search for and record the plastic.
