POLLUTION
We know that much of the plastic in the ocean comes from land. However, little is known about how this waste is transported to the ocean. This study attempts to provide some information using GPS technology.
Plastic degradation (and therefore the release of toxic products) is lower in open sea conditions (distance from shore and depth).
A new study by the Woods Hole Oceanographic Institution (WHOI) shows that the efficiency of the Ocean's biological carbon pump has been massively underestimated, with major implications for future climate assessments.
To reduce noise pollution (harmful to marine mammals), a study presented to the European Parliament recommends that ships slow their sailing speed by 25%: the "blue speed".
This article deals with the way in which anchoring ships, and especially those of large tonnage, will leave their mark on the seabed. During the Covid pandemic, many ships had to be anchored for long periods, and the anchor chains swung over the seabed, causing considerable damage to benthic ecosystems, depending on the nature of the soil.
The North Pacific waste vortex is mainly fed by the fishing activities of the most industrialized countries.
The vast majority of plastic found in whales comes from eaten animals that have previously ingested it. Krill-eating whales ingest far more plastic than fish-eating whales.

Invertebrates" living on the ocean floor are particularly sensitive to plastic pollution. Measurements of the quantity of plastic in their organisms prove to be perfect bio-indicators.
Microplastics are very present in the planktonic prey of coral and fish. They accumulate in the food chain. Scientists are increasingly aware of the dangers to organisms.
Microplastics are omnipresent not only in the ocean, but also in salt marshes (see example here from Bangladesh). This represents a high level of human exposure to this pollution.
Plastic pollution is providing new attachments for coastal species, which are now settling in the open sea. Barnacles, anemones, crustaceans (...) now attach themselves to drifting plastics, creating new ecosystem dynamics.
This article shows the importance of a better understanding of the plastic cycle in the environment (origin, transport, decomposition). This would help minimize human exposure to plastic pollution.
The "7th continent", the gigantic plastic landfill between Hawaii and California, was discovered in 1997. Since then, this ocean of plastic has been observed, analyzed and, above all, feared by the scientific community, as it continues to grow.
Fishing and aquaculture activities generate 4,600 tonnes of plastic waste per year. This study describes a system for recovering floating debris generated by tuna fishing. tuna fishing.

A research group has identified the mechanisms by which plastic waste bloom in estuaries. Their management could greatly reduce the presence of plastics on the high seas.
For many scientists, the data on plastic pollution in the ocean is still too limited to make any agreement or legislation effective.
