Indian sector of Southern Ocean sees rising oxygen levels, finds study
Dissolved oxygen levels in the Indian sector of the Southern Ocean (ISSO) have significantly risen over the past three decades, even as oceans elsewhere are showing the trend of declining oxygen levels, a study by scientists at a Goa-based institute has found. The scientists attributed the oxygenation primarily to enhanced ocean ventilation - the process through which surface waters are mixed and transported into the ocean interior, replenishing oxygen at greater depths. Oxygenation in the ISSO…
