The image is of NOAA Scuba Diver Joe Hoyt (taken by fellow NOAA diver Tane Casserley), diving in Middle Island Sinkhole near Alpena, Michigan. Joe is monitoring and taking a sample from a metabolism chamber of Sulfur-rich, Oxygen-poor groundwater that pours into the sinkhole, underlying the freshwater of Lake Huron.
It can be seen on page 48 of the magazine.
