Evidence of post-Pleistocene faults on New Jersey Atlantic outer continental shelf
Recently obtained high-resolution seismic profiles (400-4,000-Hz band) show evidence of faults in shallow sedimentary strata near the edge of the Atlantic continental shelf off New Jersey. Apparent normal faults having a throw of about 1.5 m displace sediments to within 7 m of the sea floor. The faults appear to be overlain by undeformed horizontal beds of relatively recent age. Several faults 1 t

Residues of DDT and DDE in livers of waterfowl, northeastern Louisiana--1970-71
A study was conducted to determine the levels of DDT and DDE in the livers of 10 species of waterfowl collected in Louisiana from 1970 to 1971. Livers of 48 of 50 specimens contained detectable levels of DDT and/or DDE. DDT residues ranged from 0.01 to 10.90 ppm; DDE levels ranged from 0.02 to 38.69 ppm.

Residues of organochlorines and heavy metals in ruddy ducks from the Delaware River, 1973
In December 1973, eight ruddy ducks killed in an oil spill on the Delaware River were collected to be analyzed for residues of environmental pollutants. Whole carcasses were analyzed for organochlorine pesticides and livers were examined for lead, cadmium, and mercury. Residues of polychlorinated biphenyls and DDT and/or its metabolites were present in all carcasses. Dieldrin and hexachlorobenzene

Chemical residue content and hatchability of screech owl eggs
Eggs of wild Screech Owls were collected from nests in northwestern Ohio in 1973. One egg was taken from each of 19 nests near the start of incubation. Mean shell thickness in these 19 eggs and mean thickness of 16 unhatched eggs did not differ from 49 archival eggs collected in Ohio and Pennsylvania prior to the widespread use of organochlorine pesticides. Residues were generally low although all
