During the Chilean earthquake of May 22, 1960, intensity 8.5, 4 of 8 wells in Puerto Rico equipped with automatic recorders, recorded seismic fluctuations. The maximum double amplitude, 0.05 ft, was recorded at a well in bedrock near Coamo. Double amplitudes in 3 other wells ranged from slightly less than .01 to .02 ft. Following the Puerto Rico earthquake of Aug. 2, 1961, intensity about 5.5, sei

In May 1963, the President's Science Advisory Committee issued a report entitled Use of Pesticides.17  the President already had requested the responsible federal agencies to implement the recommendations in the report. One of these recommendations was to provide for the development and coordination of a pesticide-monitoring program conducted on a continuing basis, by federal agencies to obtain ti

The principal diatoms collected at 14 stations in Lake Superior were Cyclotella "glomerata-stelligera" [= C. glomerata and C. stelligera combined], Cyclotella "ocellata-kutzingiana", Fragilaria crotonensis, and Rhizosolenia eriensis. Concentrations were heaviest in the Apostle Islands region (up to 2,160 per ml) and lightest northwest of the Keweenaw Peninsula (68 to 78 per ml). Species compositio

The principal source of ground water throughout a large part of central and northeastern New Jersey is the aquifer in the Brunswick Shale -- the youngest unity of the Newark Group of Triassic Age. Large-diameter public-supply and industrial wells tapping the Brunswick Shale commonly yield several hundred gallons per minute each. Virtually all ground water in this aquifer occurs in interconnectin

Colorimetric methods are described for the detection of residues of the selective lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), in natural waters and fish tissues. Solvent extraction and anion exchange were used to separate and concentrate the lampricide, and to reduce high background colors which often interfere with the determinations. Data from the Pentwater and Muskegon Rivers (Michigan)

Water samples were collected for chemical analysis during eight cruises of the U.S. Bureau of Commercial Fisheries M/V CISCO in south-central Lake Huron in June-October 1956. Temperature, pH, conductivity, and the concentrations of Na+, K+, Ca++, C1-, SO4-, SiO2, and dissolved oxygen were determined for 233 samples from stations at the mouth of Saginaw Bay and along a transect from Harbor Beach, M

For many years river engineers and geomorphologists have sought a rationale for the general similarity that can be observed among river channels from various environments. Some aspects of this general comparability were noted a century ago by Playfair, and other aspects were examined in a more quantitative way approximately 10 yr ago by R. E. Horton. Such similarities with respect to the channel c
