Effects of irrigation pumping on the ground-water system in Newton and Jasper Counties, Indiana
Flow in the ground-water system in Newton and Jasper Counties, Indiana, was simulated in a quasi-three-dimensional model in a study of irrigation use of ground water in the two counties. The ground-water system consists of three aquifers: (1) a surficial coarse sand aquifer known as the Kankakee aquifer, (2) a limestone and dolomite bedrock aquifer, and (3) a sand and gravel bedrock valley aquifer

Sample mine-site permit application (hydrologic assessment)
Hydrologic data are presented that may be useful in the permitapplication procedure required under current Office of Surface Mining regulations. The material is presented in a format which may serve as a guide for subsequent permit applications. Data on the quality and quantity of surface water and ground water for the mine plan, adjacent, and general areas are presented. The data are presented in

Morphology and processes associated with the accumulation of the fine-grained sediment deposit on the southern New England shelf
A 13,000 km2 area of the southern New England Continental Shelf which is covered by anomalously fine-grained sediment has been surveyed by means of high-resolution, seismic-reflection and side-scan sonar techniques to map its morphology and structure, and a near-bottom instrument system contributed to understanding present activity of the deposit. Seismic-reflection profiles show that the fine-gra

Simplified method of deep-tow seismic profiling
To improve resolution of seismic-reflection profiles in continental slope water depths of 900 to 1500 m, a single hydrophone was towed about 150 m off the bottom to receive reflected signals from a surface-towed sparker sound source. That deep-towed hydrophone data show that valleys which appear V-shaped in records from a surface-towed hydrophone are flat-bottomed, and that subbottom reflections f

Comparative hatchability of lake trout eggs differing in contaminant burden and incubation conditions
In 1972, fertilized eggs of lake trout (Salvelinus namaycush) from the Marquette (Michigan) State Fish Hatchery (where levels of contaminants are relatively low) and eggs from lake trout collected in Michigan waters of Lake Michigan near Saugatuck and Charlevoix (where levels of PCB's and DDE are elevated) were incubated at hatchery temperatures (6° C) and at temperatures simulating the natural te
