Scientists have conducted a thorough investigation into the Calypso Deep, also known as Oinousses Deep, which is the deepest point in the Mediterranean Sea, reaching a maximum measured depth of 5,122 meters. Located in the southeastern part of the Ionian Sea within Greece's exclusive economic zone, this site has been found to be heavily polluted. The study, published in the Marine Pollution Bulletin, highlights that a range of waste materials including plastics, glass, metal, and paper were discovered within this deep-sea location. The alarming findings of the research indicate that plastics account for nearly 90% of all the contaminants found in Calypso Deep, underscoring the dire state of marine pollution in this region. The concentration of waste in this area is quantified at 26,715 pieces of garbage per square kilometer, marking it as one of the highest recorded concentrations of debris in oceanic depths. Researchers assert that this data reveals it to be the second-highest known accumulation of waste in ocean depths exceeding 2,000 meters, highlighting the severity of the environmental crisis at play. These findings serve as a stark reminder of the pervasive nature of ocean pollution, raising critical questions about marine health and the effectiveness of current waste management practices on land. The stark reality of human impact on even the most remote parts of the ocean signifies the urgent need for stronger international regulations to combat marine litter and protect our oceans from further degradation, stressing that no part of the seas remains untouched by human waste.
