The plastic debris of the North Atlantic is inexplicably missing

the plastic debris collected from the North Atlantic

there is a vast unknown sea area in the west of the North Atlantic. In this area, the sea water accumulates the debris of various high concentration plastic products, which is similar to the plastic debris observed in the famous "Great Pacific Garbage belt"

in the journal Science, there is a report on Atlantic 4. The specification of oil uses plastic debris jointly studied by researchers from the Marine Education Association, the woodsholeoceanographic Institute and the University of Hawaii

the report is based on data collected by undergraduate students for more than 22 years. The report shows that more than 64000 unique plastic fragments are collected from 6100 places every year for sampling research. These plastic fragments were collected by a special collection of plankton and plastic fragments on the ocean surface

the highest concentration of debris of these plastic products is at 32 ° north latitude (about Atlanta, Georgia), and extends to the range of 22 ° – 38 ° north latitude

most of the plastic fragments are PE or PP, which is a few millimeters in size. They have become a special "plankton" in the ocean. With the passage of time, some organisms will be parasitic on the plastic debris, and their physical properties may be changed and slowly sink to the seabed

the simulation database established by the University of Hawaii explains why China has overcome the world's difficult problem of nano film material detection. Laminar flow makes plastic debris accumulate in an unknown sea area in the sea, rather than on the coast, which also reflects the contribution of basic marine physics

"This important database provides the first rigorous scientific estimate of the large number of plastic floating objects in this vast sea area," said karalavenderlaw, a marine scientist and the main author of sciencepaper

however, there is a strange discovery. According to law, although the treatment of plastic products is increasing now, the remains of these high concentration plastic fragments have not increased in the research reports in the past 22 years, and the whereabouts of those disappeared plastic fragments are unknown

richardthompson, from the University of Plymouth, UK, is also committed to the study of plastic debris in the North Atlantic, He said, "this is a very interesting topic. Although there is no clear document to indicate the unified whereabouts of these large amounts of plastic debris in the North Atlantic, we cannot easily infer that they flow to any other place or have any habitat. What we should do is to try to find a reasonable way to deal with these existing plastic waste."

note: we should also pay attention to regular inspection and maintenance of the main engine, oil source and control system. The reprint of this book is for the purpose of transmitting more information, and does not mean to agree with its views or confirm the authenticity of its content
