Comparison of solid-phase and pore-water approaches for assessing the quality of marine and estuarine sediments Comparison of solid-phase and pore-water approaches for assessing the quality of marine and estuarine sediments
As part of our continuing evaluation of the pore-water approach for assessing sediment quality, we made a series of side-by-side comparisons between the standard 10-day amphipod whole sediment test with the corophiid Grandidierella japonica and a suite of tests using pore water extracted from the same sediments. the pore-water tests evaluated were the sea urchin (Arbacia punctulata)...

Assessment of sediment contamination at Great Lakes Areas of Concern: the ARCS Program Toxicity-Chemistry Work Group strategy Assessment of sediment contamination at Great Lakes Areas of Concern: the ARCS Program Toxicity-Chemistry Work Group strategy
In response to a mandate in Section 118(c)(3) of the Water Quality Act of 1987, a program called Assessment and Remediation of Contaminated Sediments (ARCS) was established. Four technical work groups were formed. This paper details the research strategy of the Toxicity-Chemistry Work Group. The Work Group's general objectives are to develop survey methods and to map the degree of...

Food preferences of spring-migrating blue-winged teal in southwestern Louisiana Food preferences of spring-migrating blue-winged teal in southwestern Louisiana
We studied effects of pair status, molt intensity, and year on food selection by migrating male blue-winged teal (Anas discors) in southwestern Louisiana during springs 1990 and 1991. Diets consisted primarily of animal foods; but plant material, consisting mostly of seeds, comprised as much as 44%. There was no difference in animal food consumption by paired and unpaired males; however...

Hydrogeologic maps of the central Oklahoma aquifer, Oklahoma Hydrogeologic maps of the central Oklahoma aquifer, Oklahoma
This report presents hydrogeologic maps of the Central Oklahoma aquifer. The maps were prepared by measuring water levels in wells during the winder of 1986 and 1987; examination of geophysical logs to determine the altitudes of the top of selected geologic units and the base of fresh ground water; and compilation of existing information on the stratigraphy of selected geologic units and...

Techniques for estimating 7-day, 10-year low-flow characteristics for ungaged sites on streams in Mississippi Techniques for estimating 7-day, 10-year low-flow characteristics for ungaged sites on streams in Mississippi
Mississippi State water laws require that the 7-day, 10-year low-flow characteristic (7Q10) of streams be used as a criterion for issuing wastedischarge permits to dischargers to streams and for limiting withdrawals of water from streams. This report presents techniques for estimating the 7Q10 for ungaged sites on streams in Mississippi based on the availability of baseflow discharge...
