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.
