Plastic Ocean: How a Sea Captain’s Chance Discovery Launched a Determined Quest to Save the Oceans


In 1997, environmentalist Charles Moore discovered the world’s largest collection of floating trash—the Great Pacific Garbage Patch (“GPGP”)—while sailing from Hawaii to California. Moore was shocked by the level of pollution that he saw. And in the last 20 years, it’s only gotten worse—a 2018 study has found that the vast dump of plastic waste swirling in the Pacific Ocean is now bigger than France, Germany, and Spain combined—far larger than previously feared.

In Plastic Ocean, Moore recounts his ominous findings and unveils the secret life of plastics. From milk jugs and abandoned fishing gear to polymer molecules small enough to penetrate human skin and be unknowingly inhaled, plastic is now suspected of contributing to a host of ailments, including infertility, autism, thyroid dysfunction, and certain cancers. An urgent call to action, Plastic Ocean’s sobering revelations have been embraced by activists, concerned parents, and anyone alarmed by the deadly impact and implications of this man-made environmental catastrophe.

Great Pacific Garbage Patch Samples Analyzed

We are analyzing 2014 samples!

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

  • Because it gives new readers context. What are you about? Why should they read your blog?
  • Because it will help you focus your own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

  • Why are you blogging publicly, rather than keeping a personal journal?
  • What topics do you think you’ll write about?
  • Who would you love to connect with via your blog?
  • If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.

First Long Term Monitoring in the Great Pacific Garbage Patch

In 1997, Captain Charles Moore was sailing from California to Hawaii, and what he saw was disturbing. In the middle of the Pacific Ocean, far from land, he saw a vast area where large amounts of trash was accumulating. Because of these concerning observations, he decided he wanted to bring the situation to the attention of the world.

The first study of debris in the Great Pacific Garbage Patch (also known as the North Pacific Gyre) took place in 1999. Eleven sites were sampled in an area identified as near the center of the gyre. What were the results? We found the ratio of plastic to plankton in this area to be 6:1 by weight. Meaning that for every 6 grams (or pounds) of debris, there was only 1 gram (or pound) of plankton. What was even more disturbing was the fact that the samples were found after the fact, not to be collected in the center of the gyre.

So we now had an estimate for how much was out there…but what did we want to know next?

The most pressing question was…is the amount of debris going up or down…is it getting better or worse?

Since that initial study in 1999, Captain Moore has gone back out to the Garbage Patch four more times to survey the same 11 stations. Making this project the first long-term survey of this area. We are currently working up the 2019 samples at the Moore Institute for Plastic Pollution Research. The results of this long term monitoring survey will be written up and published in 2021. Through this research, we are looking to answer that question of “Are things getting better or worse?”

Preliminary observations indicate that things may indeed becoming worse, as the amounts of plastic in the samples were far more in 2019 than in previous years. However, we need to also look at many other factors, such as proximity of each sample to the gyre, weather conditions, and ocean currents before we can confirm if the numbers reflect an increasing amount of debris in the Garbage Patch.

You can help us to finish up this study and become a part of this important research. We are looking for funding to finish up sample analysis.
