Changes in the visual pigments of trout
The proportions of two visual pigments (rhodopsin and porphyropsin) were examined in four species of trout under experimental and natural conditions. Brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri), and brown trout (Salmo trutta) have different relative proportions of visual pigments in their retinae. The visual pigment balance in wild cutthroat trout (Salmo clarki) is related

Fluvial-sediment discharge to the oceans from the conterminous United States
This report is a contribution to the UNESCO-sponsored project of the International Hydrological Decade called the World Water Balance. Annual fluvial-sediment discharge from the conterminous United States averages 491,449,600 short tons, of which 14,204,000 is discharged to the Atlantic Ocean, 378,179,000 to the Gulf of Mexico, and 99,066,600 to the Pacific Ocean. Data from 27 drainage areas were

Water facts and figures for planners and managers
Water is defined in terms of its chemical composition and dominant physical properties, such as expansion on freezing and high surface tension. Water on the earth is about 97 percent in the seas, 2 percent in glacier ice, principally Greenland and Antarctica. Man is left with less than 1 percent as liquid fresh water to sustain his needs. This is possible under good management because water moves

Role of water in urban planning and management
Concentrations of people in urban areas intensify water problems such as flooding and pollution, but these deleterious effects on water resources can be minimized or corrected by comprehensive planning and management. Such planning of the water resources of an urban area must be based on adequate hydrologic data.
Through the use of a matrix, urban water problems can be evaluated and availability o

Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10
Leg 10 interstitial water analyses provide new indications of the distribution of rock salt beneath the floor of the Gulf of Mexico, both confirming areas previously indicated to be underlain by salt bodies and extending evidence of salt distribution to seismically featureless areas in the Sigsbee Knolls trend and Isthmian Embayment. The criterion for presence of salt at depth is a consistent incr

Thickness of the American woodcock eggshell, 1971
Eggs or empty shells of the American woodcockwere collected from 10 states in 1971and shell thickness (mean of clutch means) was compared with that of eggs collected from 16 states during the years 1859-1939. The 1971 shells (n = 91) from hatched eggs or those containing fully developed embryos were about i0 percent thinner (P
