Fluctuations of ground-water levels in Puerto Rico resulting from earthquakes (1959-1961) Fluctuations of ground-water levels in Puerto Rico resulting from earthquakes (1959-1961)

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...

Monitoring wildlife for pesticide content Monitoring wildlife for pesticide content

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...

The distribution and abundance of planktonic diatoms in Lake Superior The distribution and abundance of planktonic diatoms in Lake Superior

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

Directional hydraulic behavior of a fractured-shale aquifer in New Jersey Directional hydraulic behavior of a fractured-shale aquifer in New Jersey

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

Field application methods for recovery of the selective lampricide, 3-trifluoromethyl-4-nitrophenol Field application methods for recovery of the selective lampricide, 3-trifluoromethyl-4-nitrophenol

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...
