Researchers from the Environmental Protection Agency (EPA) monitored water movement and oxygen concentrations at the 14-16 meter depth, where it’s most likely for hypoxic water to intrude into shallower areas with normal oxygen concentrations. Organisms that live there aren’t adapted for those lower oxygen levels, so it’s also where those intrusions can have serious negative impacts on aquatic life that can’t survive these conditions for more than a few minutes.
