Marine debris is a problem on the coast around the world – and the Gulf of Mexico is no exception.
From February 2015 to August 2017, the researchers retained the plaque for seaweed which sank each month on the coastline at 12 different locations on nine barrier islands from the North Padre Island, Texas to Santa Rosa, Florida.
The study found that 10 times more garbage is washed on the Texas coast than any of the other Gulf states throughout the year.
The bulk of the garbage, 69-95 percent, was plastic, according to the study. Plastic elements include bottles and caps for bottles, straws and broken plastic pieces. The researchers also noted that more garbage is washed on the shore during spring and summer. This may be because more people are out and water at this time.
The researchers also found that the amount of residues accumulated along the coastline can be predicted with high confidence in areas with high freshwater flows.
