Abstract: A large deep-water ocean outfall discharging ˜880 x 106 liters day (230 million gallons day of treated wastewater effluent was inspected with a one-man submersible and documented with a collection of 35 mm slides and ˜35 hours of video tapes. A serendipitous result of this primarily engineering maintenance study was a pictorial documentation of an abundance of organisms on and next to the structure. This qualitative picture provides support to an extensive, quantitative monitoring program (1985 to present) finding that the area supports a highly diverse and abundant fauna.
