World's First Aerial Survey of Great Pacific Garbage Patch: 'It's Worse Than We Thought'

Boyan Slat, the 22-year-old Dutch inventor and CEO behind The Ocean Cleanup, announced today preliminary results of the organization's latest major research mission, the Aerial Expedition, the first-ever aerial survey of an ocean garbage patch.

"One of the things that we are already able to share is right at the edge of [the Great Pacific Garbage Patch], we came across more objects than we were expecting to find in the center of the garbage patch," Slat said at a press conference at Moffett Airfield in Mountain View, California.

"During a period of just two and a half hours, our crew observed more than a thousand large objects of plastic floating underneath this aircraft," he continued. "Although we still need to get a detailed analysis of the results, it's really quite safe to say that it's worse than we thought. Again, this underlines the urgency of why we need to clean it up and that we really need to take care of the plastic that's already out there in the ocean."

The Ocean Cleanup's Aerial Expedition aims to accurately measure a particularly large and harmful type of marine debris known as ghost nets. The Ocean Cleanup crew determined that quantifying such objects will help resolve the "last piece of our puzzle" following last year's Mega Expedition, a 30-day reconnaissance mission that produced the first high-resolution map of the Great Pacific Garbage Patch, but came short in determining just how much plastic was in the ocean, especially larger items.

Items the crew spotted from yesterday's first test flight included ghost nets, discarded fishing gear, buoys, crates and other unidentifiable objects. The Ocean Cleanup

"We discovered that the conventional method of measuring ocean plastic, using nets of less than a meter (3 ft) wide, was inaccurate because it seriously underestimated the total amount of plastic. The reason for this is simple: the larger the objects, the rarer they are by count," the Ocean Cleanup team said.

So, instead of using boats to count ocean plastic, the team turned to planes. To conduct their aerial survey, a C130 Hercules aircraft was fitted with state-of-art sensors from Teledyne Optech, whose Coastal Zone Mapping and Imaging Lidar (CZMIL) can detect objects at oceanic depths of tens of meters. This technology can also provide researchers with a weight estimate by registering the size of the found objects.

The aircraft, dubbed Ocean Force One, is scheduled to make several flights from Sept. 26 to Oct. 7. These low-speed, low-altitude flights will inspect an estimated 6,000 square kilometers of the ocean, more than 300 times the area explored at the Mega Expedition.

Yesterday, mission crew completed the first of two test flights above Moffett Airfield to calibrate the aircraft's ocean plastic sensors and familiarize themselves with the survey protocol. The aircraft flew along the Northern boundary of the Great Pacific Garbage Patch, the plastic accumulation zone between Hawaii and California.

The Aerial Expedition's findings will be combined with the data collected on the Mega Expedition, resulting in a study expected to be published in early 2017.

In the video below, Slat gives a tour of the aircraft and the concept behind the mission:

"In order to solve the plastic pollution problem, it is essential to understand its dimensions," Julia Reisser, oceanographer and expedition leader, wrote in a blog post. "Knowing how much and what kind of plastic has accumulated in the ocean garbage patches is especially important. This determines the design of cleanup systems, the logistics of hauling plastic back to shore, the methods for recycling plastic and the costs of the cleanup."

Following the test flights, a team of 10 researchers, three sensor technicians and seven navigation personnel will participate on two long flights flying at a low airspeed of 140 knots and an altitude of 400 meters as it maps the garbage patch, according to Reisser.

"Four experienced observers will scour the ocean surface from the aircraft's open paratroop doors, while two computer operators log the data," Reisser wrote. "The pilots and navigator will also search for ocean plastic from their seats in the cockpit, where another computer operator will log their sightings."

"The carbon emissions generated by the aircraft will be offset through clean energy compensation," the team pointed out.

The visual survey is the final major research mission before the actual start of Slat's ambitious ocean cleanup effort. "This is really the last reconnaissance step before we start the real cleanup," he said at today's press conference.

At the young age of 17, the aerospace engineering student made headlines and inspired people around the world after coming up with a plastic-capturing concept that involves a massive static platform and long floating barriers that passively corrals plastics with wind and ocean currents.

The Ocean Cleanup, headquartered in Delft, The Netherlands now employs approximately 50 engineers and researchers.

In June, the Ocean Cleanup deployed a 100-meter clean-up boom, nicknamed Boomy McBoomface, in the North Sea in The Netherlands.

The organization said that the next milestone for The Ocean Cleanup after the Aerial Expedition will be its Pacific Pilot, which is scheduled for launch in the second half of 2017.

The Ocean Cleanup's mission is to rid the world's oceans of plastic, a scourge that severely pollutes and damages ocean ecosystems and economies. About 8 million tons of plastic enters the oceans each year.

At today's press conference, Slat warned that large pieces of plastic can "crumble down into those small microplastics ... and that has a tremendous environmental impact if it ends up in the food chain." He also noted that ghost nets can be harmful because they can cause entanglements of aquatic life as well as ship propellors.

Full deployment of the Ocean Cleanup system is scheduled for 2020.

How Big Is Your Environmental Footprint?

If you want to make a positive change this Earth Day but don't know where to start, one of best things you can do is take an honest look at your environmental footprint. For instance, how much water are you wasting? How much plastic are you throwing out? How much planet-warming carbon are you producing?

Luckily, there are many online calculators that crunch through your consumption habits. While the final tally might be daunting, it's the first step in living more sustainably.

6 Simple Tips to Reduce Waste So Every Day Is Earth Day

Earth Day 2018 is focused on the all-important theme of reducing plastic litter and pollution. Of course, we shouldn't just reduce our plastic footprint, we should try to reduce waste in all shapes, sizes and forms. It's said that the average American generates a staggering 4 pounds of trash every day—but you don't have to be part of that statistic.

Here are six entirely manageable tips and tricks to help you cut waste.

5 Environmental Victories to Inspire You This Earth Day

Planet Earth is at a crisis point. Researchers say we have to begin reducing carbon dioxide emissions by 2020 if we want to meet the temperature goals outlined in the Paris agreement and avoid catastrophic climate change.

The work to be done can seem overwhelming. A survey published this week found that only 6 percent of Americans think we will succeed in reducing global warming.

Iceland to Resume Killing Endangered Fin Whales

By Kitty Block

Iceland seems to be the most confused of nations when it comes to whales. On the one hand it attracts international tourists from all over the world to go out and see whales as part of their encounters with Iceland's many natural wonders. On the other hand it kills whales for profit, with some portion of the kill even being fed to some of the same tourists in restaurants and cafes.
