Dissolved Oxygen Maps for Summer 2000
During the summer of 2000 hypoxia (defined as dissolved oxygen (DO) concentrations below 3.0 mg/l) got off to an early start with an onset on or about July 2, 2000. By the middle of July hypoxic conditions affected 447 square kilometers (173 square miles) of Long Island Sound, a record for July. By August conditions had improved dramatically. During the August water quality surveys no hypoxia was observed after August 6. Using our data and weather patterns it was estimated that the end date for hypoxia was August 6 for a total of 36 days.
