Greenpeace Visits Wilmington North Carolina

“They’ll figure it out.” My friend said to me after we visited the Greenpeace ship, Arctic Sunrise, this past Saturday downtown Wilmington, NC. “They, who’s they?” I retorted. I wanted my friend to come to hear what Greenpeace had to say about the destructive entities of coal. He grew up in North Carolina and devoured the slogan “Clean Coal” like a McDonald’s Big Mac. It looks good, it smells good, it tastes good, but far from being good for you. He, like many of us (including me not long ago) believes that the government will figure it out -that they have the Americans best interest at stake. And they do, except they have to answer to big business first.

Why would I be mentioning this in my Plastic Ocean blog? Like the plastics industry, coal, gas, petroleum and chemical companies are among the richest and strongest companies in the world. Our government knows we need them for jobs and we need the energy they provide along with other perks. In regards to subsidizing oil, Obama said tonight in his State of the Union Address, ”We (our government) need to stop giving millions of dollars to oil companies. I don’t know if you noticed but they’re doing all right on their own.” There was no applause after that statment, but I was cheering from the couch.  But yet, he still pushed “clean coal.”
It doesn’t matter if you are a Democrat, Republican, or Independent. Corporate interests have far more influence on our government policies, so really you’re just choosing which financial backer happens to be holding the strings. That said, how we spend our money affects corporations. OUR money does the voting. We need to all start thinking in terms of how we vote with our money.

I told my friend that if he wanted to help promote the change necessary to “figuring it out” he could stop turning on every light in his place when he wakes up at 6am. Read labels and buy products that are made out of and packaged in recycled materials. Drive less, walk more, eat local foods, don’t take the free mint if it’s wrapped in plastic, bring your own bag, cup, eco ware, refuse single-sized servings, don’t drink bottled water. Reducing the use of heat, air, gas, and plastic will impact the industries that market them and they will be forced to change what they offer. It really is that simple. Vote with your dollar for change. And support non-profits like Greenpeace who doesn't take a penny from industry or government. People committed to clean air, land, and water and to the health of all living things. Thank you David Pinsky for getting UNCW fired up about this past weekend event.

Questions Concerning the Great Pacific Garbage Patch

A recent survey done by an Oregon State University assistant professor Angelicque "Angel" White concluded that commonly quoted estimate of the North Pacific Garbage Patch is "grossly exaggerated." And its true, an island of trash a thousand miles away from land is not accurate, nor saying its twice the size of Texas is accurate either.  Its actually worse.  Because if it were, we could clean it up far more easily.  Here is a photo of what her research found out there.  The sample below it is what we found in the general area.   We had a bottle cap in nearly every one of the 54 samples and sometimes more than one. We weren't the only ones collecting them. Bottle caps are the #2 item found on beaches next to cigarette butts (incidentally, made of plastic not cotton).

Sample of the N. Pacific Garbage Patch, Oregon State 2010

  

Sample I witnessed with AMRF 2009

The problem is by the time most of the plastic reaches this location, its broken down into small pieces.  Nice bite size fragments for surface feeding fish.  We agree that this is what the said Garbage Patch looks like and we agree that fish are eating it.   What I don't agree with is publicly degrading the work of another researcher. And It is poor science if a scientist degrades the work of another verbally without conducting the same experiment and coming up with a different conclusion regarding the 6-1 plastics to zooplankton.

The original expression was that plastic is accumulating in an area twice the size of Texas and then it manifested to an island of plastic twice the size of Texas.  The original claim is correct.  That was the size of the area sampled by Charles Moore and plastic was found in every sample.  It has been the media that has gotten it wrong. Mind you sampling is done with a trawl with an opening less than a meter across and less than a 1/2 meter deep.  Its like sampling just a few inches of one thread on a quilt 4 miles in diameter.  To find any quantity of plastic 2000 miles away from any land mass is not be undermined as trivial which is a tone conveyed in this article.

After being in both the North Pacific and Atlantic as well as South Atlantic, I would say on average what we pulled out of the Garbage Patch had far higher concentrations.  Our surface tows average 1 hour.  So the comment " A recent trawl (singular) White conducted in a remote section of water between Easter Island and Chile pulled in no plastic at all." First of all was only one sample and second I would have to ask, how long was your tow?  It could be comparing apples to oranges.  The problem with assessing the scale of this problem is, like the article says, "plastic is not evenly dispersed" so they could easily missed accumulations of plastic by running short timed samples.

I've been to 3 of the 5 gyres and regardless of size, plastic is everywhere.  I haven't seen one sample come back that hasn't had plastic - 54 samples in the N. Pacific, 19 samples in the N. Atlantic, and 64 in the S. Atlantic.  Lastly, it has been the media that has taken liberty in hyperbole.  The first thing Captain Moore said to me when I met him for the first time was, "it isn't an island of trash out there. That has been journalistic liberties."

Though I agree the hyperbole has created an illusion of an island, the problem is much larger than an island of trash.  Below is Marcus Eriksen's rebuttal and far more eloquent. 


Beyond the absurdity of a “Texas-sized Garbage Patch” lies a larger menace of plastic pollution in the world’s oceans

Media is sometimes the tail that wags the dog of science.  One oceanographer described finding plastic in his relatively tiny Texas-size study area of the North Pacific Ocean, while another began describing these areas of concentration as “garbage patches”.  A mis-information frenzie birthed a mis-conception of an island of trash.  Hurry, someone plant a flag - sell real estate!  Disappointing to the entrepreneurial spirit that aimed to fix it for a fee, there are no such islands.  They do not exist.  Having traveled 20,000 miles across 4 of the 5 subtropical gyres, returning from crossing the South Atlantic Gyre in December 2010, I assure you that reality is much worse.

It’s a patchy patch.  In 1999 Captain Charles Moore, founder of the Algalita Marine Research Foundation based in Long Beach, CA, published an observed 6:1 weight ratio of plastic to plankton in the swirling center of the North Pacific Subtropical Gyre.  I joined him in 2005 and 2008 to the same region.  In this decade of research, the foundation was heavily criticized by other oceanographers for quantifying plastic this way.  What was hidden in this criticism was the fact that the science of Oceanography was caught off guard.  No one knew of this plastic plague on the world’s oceans, until a Long Beach surfer/sailor turned scientist made it known.  It is true that plankton is extremely variable, and can bloom and dissipate with the season, temperature, moonlight, and a dozen other variables, therefore the margin of error is huge.  But the plastic/plankton ratio serves a good anecdote for relative abundance of plastic to available food for scavenging fish and filter feeders, like from jellies to baleen whales.  So, it’s important to describe plastic to plankton ratios as an anecdote, but not worth quantifying. 

1999 was not the first time scientist studied plastic pollution in the ocean.  Thor Heyerdal observed plastic in 1969 crossing the North Atlantic on Ra I.  Two years later Edward Carpenter, from Woods Hole Oceanographic Institution, netted pellets and fragments of plastic pollution between the east coast and Bermuda. Plastic pollution in the North Pacific Gyre was first described by Robert Day in 1989 near the coast of Japan, and in the South Atlantic Gyre near Cape Town, South Africa in 1980 by Robert Morris of the Institute of Oceanographic Science in the UK.  It was a quiet, poorly-understood menace that palled in significance and interest to oceanographers.  Then the story broke about an island of plastic, with sensationalized accounts beyond science, mythological masses of synthetic detritus, an illusive terra aqua.

“Somebody do something,” cried the ocean advocates, artists, celebrities and politicians.  And the scientists followed.  Media called them to action.  But not before the industrialists.  A problem precedes a solution ready to sell.  Groups with little or no experience at sea rose to the occasion with fanciful technofixes, contraptions of grandeur, robotic vagabonds to sieve the sea in solitude and bring the trash back to land, or parachutes that spin sickle-shaped islands that net plastic pollution in their path.  All have failed, realizing that going to the ocean to remove floating plastic particles is like standing on the top of a skyscraper with a vacuum cleaner to remove air pollution.  It’s not impossible, just impractical.  There is no island to retrieve.  We have run expeditions across the North Pacific Gyre, North Atlantic Gyre, Indian Ocean Gyre, and in December 2010 we crossed the South Atlantic Gyre.  We found plastic in every surface trawl, in varying concentrations.  Imagine a handful of degraded plastic confetti spread across a football field of the ocean surface. That’s as thick as it gets, but it’s everywhere.  It’s a think plastic soup over 2/3rds of the earth’s surface.  So far the 5 Gyres Institute has traveled to 4 of the 5 subtropical gyres in the world, conducting over 400 surface trawls, with plastic in every one.   That is the menace of plastic pollution.  It’s everywhere, thinly distributed, and extremely impractical to clean up at sea.

But if no one cleans it up, will the garbage patches keep growing?  No.  Studies in the North Atlantic Gyre and North Pacific Gyre have been repeated with interesting results.  There’s no massive trend in plastic accumulation over time. Kara Lavender Law, of Sea Education, compiled data from 22 years of data from the North Atlantic Gyre, the same area that Carpenter studied 3 ½ decades earlier.   “We observed no strong temporal trends in plastic concentration…”  Last week we returned from 31 days crossing the South Atlantic Gyre.  As we sailed into Cape Town we revisited half of the locations that Morris studied 3 decades ago and repeated his exact methods.  Though our samples have not been analyzed yet, I can anecdotally report that the samples do not appear to show a tremendous trend in plastic accumulation over this time.  Sure, there’s more, but the increase does not parallel the rapid increase in plastic production and consumption on land.  So where does it go?  We believe some sinks as absorbed chemicals, like PCBs, PAHs and other persistent pollutants, and bio fouling make smaller and smaller particles more dense than seawater.  Much of it washes ashore on islands in the gyres, like Hawaii and Bermuda, or is kicked out of the gyres onto mainland beaches as the gyre’s center wobbles east and west.  Then there’s still room for unknown answers.  What we now know is that if we stop adding more plastic to the ocean, in time the gyres will kick out the plastic pollution they currently hold.  If you want to clean the gyre, clean your beach. 

We want to know a few things.  How much plastic is out there, what is the fate of plastic in the ocean, what is the impact of plastic pollution on fish, including fisheries we harvest to feed the world, and how do we end the plague of plastic in the ocean?  The 5 Gyres Institute will sail across the South Pacific Gyre in the Spring of 2011 from Valdivia, Chile to Easter Island.  You can follow this expedition on 5gyres.org.  In January and February 2011, at the moment I’m writing this paper, we are crossing the South Atlantic Gyre again.  The South Pacific will be our 5^th gyre, and provide a snapshot of the global distribution of plastic pollution.  We will also be freezing fish to look for toxins in tissues, which we are currently doing with fish collected from South Atlantic Expedition.  Other expeditions conducted by SCRIPPS, NOAA and Sea Education, are contributing answers to these questions with rigorous science.  All of this will be shared by colleagues in March 2011 in Hawaii during the 5^th International Marine Debris Conference.

In the recent decade of rogue-science, media spun mis-information, a new revitalized science of synthetic pollution at sea has emerged, replacing confusion with clarity and commitment by many to solve the problem.  The idea of cleanup at sea is no longer a sensible option, knowing that an island twice the size of Texas is actually a thin soup 2/3rds the surface of the planet.  Sensible solutions now focus on preventing the flow of waste to waves in the first place.
