Voyage to the Pacific Ocean's garbage patch: Sadness, anger and a plea to help avoid catastrophic changes in the marine ecosystem


Editor's Note: Scuba instructor and underwater videographer Drew Wheeler  is traveling on board the Algalita Marine Research Foundation's 50-foot Ocean Research Vessel, Alguita, on a two-month voyage to sample and study portions of a 10-million-square-mile oval known as the North Subtropical Gyre (aka "Pacific garbage patch"). Wheeler and the rest of the Alguita crew left Long Beach, Calif., on June 10 with a plan to cross the International Date Line and investigate regions of reported high plastic concentrations, northwest of the Hawaiian Islands. This is his eighth blog post for Scientific

With less than 200 miles to Honolulu, we are in the final stretch of the 2009 ORV Alguita Dateline Journey, and every one of the crew can now reflect on what they have experienced and the knowledge they have gained.

Scuba Drew, Alguita, plastic, PacificPersonally, I have learned several things on this voyage, some related to the mission of substantiating the vast amounts of plastic in the ocean and others just related to life. You can't spend over 50 days on a 50-foot boat with five other people and come away entirely the same person!Scuba Drew, Drew Wheeler, Alguita, Pacific, plastic

This journey has allowed me to experience everything from the bewilderment and amazement of swimming among the alien life forms that exist and thrive in the most remote location on the planet. To the sadness and anger I feel when I see, first hand, what we are doing to that life, which most people will never lay their eyes upon.

The increase in plastic from the 2002 voyage to now is frightening. In just seven years, it seemed to me that everywhere we went has become a "high-accumulation zone". The amount of tiny fragments and small bits of plastic that I collected and saw, either floating past the boat or in the trawl samples on any given day was flat out disgusting.Scuba Drew, Alguita, Pacific, plastic

Then add that to plastic material I saw in the water intermixed with the billions of planktonic life, and I don't need a scientific study to tell me that it is a serious problem that ultimately will affect all life on this planet. There is NO WAY a passive plankton feeder can filter out the plastic lingering among it's food supply.

Scuba Drew, Alguita, Pacific, plasticMy conclusion: we must stop this from getting worse by reducing or eliminating the use of non biodegradable plastic for disposable products and product packaging. If the increasing rate of plastic in the ocean does not change, then I do not see how we can avoid catastrophic changes in the health of our marine ecosystem and, as a result, to human life itself.Scuba Drew, Alguita, Pacific, plastic

Now that is something to think about!
