A microcomputer based system for current-meter data acquisition A microcomputer based system for current-meter data acquisition
The U.S. Geological Survey is conducting current measurements as part of an interdisciplinary study of the San Francisco Bay estuarine system. The current meters used in the study record current speed, direction, temperature, and conductivity in digital codes on magnetic tape cartridges. Upon recovery of the current meters, the data tapes are translated by a tape reader into computer...

Organochlorine poisoning of herons Organochlorine poisoning of herons
Over a period of years interested individuals have submitted many dead or moribund herons of various species to our laboratory to learn whether the birds had been affected by diseases or organochlorine poisoning. Residue concentrations in carcasses of birds and mammals are considered the best measure of sublethal exposure, whereas residues in brains are best to use for diagnosing death...

Altitude-age relationships of the lunar maria Altitude-age relationships of the lunar maria
Altitudes and relative ages of mare surface units were compared to test if a systematic correlation in height of lava eruption surfaces and age might reflect a corresponding increase in depth of the magma chamber with time; in addition the altitudes were studied to shed light on the time and place of warping of mare surfaces. The laser altimeter data from the Apollo missions and relative...

Biogenic and thermogenic gas in gas-charged sediment of Norton Sound, Alaska Biogenic and thermogenic gas in gas-charged sediment of Norton Sound, Alaska
Chemical and isotopic compositions of sediment gas from Norton Sound have been determined for near-surface, gas-charged sediments at two sites identified in acoustic profiles and bottom observations. At one site air-driven vibracorer penetrated sediment saturated with methane. The isotopic value suggests that the methane originated from active biological processes operating on peat in...

Excretion of the lampricide Bayer 73 by rainbow trout Excretion of the lampricide Bayer 73 by rainbow trout
Urinary excretion of the 2-aminoethanol salt of 2′, 5-dichloro-4′-nitrosalicylanilide (Bayer 73) in rainbow trout (Salmo gairdneri) was measured after exposure of the trout to Bayer 73 and also after intraperitoneal (ip) injection of the lampricide. Fish exposed to 0.05 mg/litre of Bayer 73 for 12 h quickly began to excrete residues in the urine. The largest amount of Bayer 73 was...
