Summary of Activity and Data Gathered: Fourteen dives were carried out in and around the two dumpsites located about 40 nm southeast of the mouth of Delaware Bay. The study was part of a coordinated effort involving surface ships (R/V ANNANDALE and R/V ADVANCE II), and ERTS overpass, and sewage release by a City of Philadelphia barge. At the Philadelphia site, no obvious layer of settling sludge was apparent in the water column nor were accumulations on the bottom identified. At the acid dumpsite, a low visibility layer and the underlying zone containing large reddish-yellow flocks above and in the thermocline were the major anomalies observed.
