1974, Hydrological Sciences Bulletin (19) 227-229
Information for comparing costs of collecting hydrometric data in different countries may promote efficiency of operations. The hydrometric programme in the United States consists of 8400 full-record stations and an equal number of partial-record stations operated by 47 district offices. A sampling of four districts selected to represent the range...

The determination of selenium by hydride generation atomic absorption spectrophotometry using zinc is widely used. Very little is mentioned, however, on possible interferences. In an attempt to use this technique for the determination of selenium in natural waters, interferences were found. The most serious interference occurred when arsenic was present....

Isotopic composition of carbon and hydrogen in some Apollo 14 and 15 lunar samples was determined by use of a newly constructed combustion line that yields low blanks for CO2 and H2. The results from combustion of fines and breccia from Apollo 14 lunar samples and of fines, breccia, and basalt from Apollo 15...

1974, Technical Report 27
Recoveries of 477 (11.8%) of 4,048 tagged parasitic-phase sea lampreys showed that lampreys moved extensively and that interchange between the Great Lakes was common. Of 93 recoveries from 2,265 tagged lampreys released below the navigation locks in the St. Marys River, 80 were in Lake Huron, 12 in Lake Superior,...

1974, Technical Report 26
The sea lamprey (Petromyzon marinus) gained entrance into Lake Superior in the early 1940's, and began making drastic inroads on the fish stocks by the early 1950's. Serious efforts to control the parasite began in 1953 with the installation of electrical barriers in streams to block spawning runs. Control measures...

A new seismological project is now underway in Puerto Rico to provide information needed for accurate assessment of the island's seismic hazard. The project should also help to increase understanding of the tectonics and geologic evolution of the Caribbean region. The Puerto Rico Seismic Program is being conducted by the...

Rates of accumulation of Fe and Mn, as well as Cu, Ni, Co, Pb, Zn, Hg, U and Th have been determined for five ferromanganese deposits from four localities in the South Pacific Ocean.Manganese is accumulating in nodules and crusts at a rate roughly equivalent to that found...

The Hawaiian Volcano Observatory (HVO) sits on the edge of Kilauea Caldera at the summit of Kilauea Volcao, one of the five volcanoes on the island of Hawaii, the largest island in the Hawaiian Islands chain. Of the five, only Kilauea and Mauna Loa have been active in the past...

Portions of highland breccia boulder 7 collected during the Apollo 17 mission were studied using UThPb and RbSr systematics. A RbSr internal isochron age of3.89 ± 0.08b.y. with an initial87Sr/86Sr of0.69926 ± 0.00008 was obtained for...

From experimental studies of gamma rays from fast and thermal neutron reactions in hydrogeneous and non-hydrogeneous, semi-infinite samples and from Monte Carlo calculations on soil of a composition which might typically be encountered on planetary surfaces, it is found that gamma rays from...

The first naturally occurring terrestrial example of vapor-liquid-solid (VLS) growth has been observed in condensates from gases released by burning coal in culm banks. Scanning electron microscopy, X-ray diffraction, and energy dispersive analysis indicate that the crystals consist of elongated rods (≈ 100...

Inspection of the Mariner 9 B-camera (resolution 100–200m) and A-camera (resolution 1–2km) photographs of Mars reveals numerous analogs of terrestrial and lunar volcanic features. In addition to the exceptionally large constructional features in the Tharsis region, many other large and small landforms present...
