Subsurface injection of treated sewage into a saline-water aquifer at St. Petersburg, Florida - Aquifer pressure buildup
J.J. Hickey
1984, Ground Water (22) 48-55
The city of St. Petersburg has been testing subsurface injection of treated sewage into the Floridan aquifer as a means of eliminating discharge of sewage to surface waters and as a means of storing treated sewage for future nonpotable reuse. Treated sweage that had a mean chloride concentration of 170...

Straczekite, a new calcium barium potassium vanadate mineral from Wilson Springs, Arkansas
H. T. Evans Jr., G. Nord, J. Marinenko, C. Milton
1984, Mineralogical Magazine (48) 289-293
Straczekite occurs as a rare secondary mineral in fibrous seams, along with other V minerals (A.M. 64-713), in ore from the vanadium mine in Wilson Springs (formerly Potash Sulfur Springs), Garland County, Arkansas. It forms soft, thin laths of dark greenish black crystals up to 0.5 mm in length. Indexed...

1984, Conference Paper, Marine birds: Their feeding ecology and commercial fisheries relationships
Food brought to nestling Rhinoceros Auklets (Cerorhinca monocerata) was sampled by applying tape or cloth muzzles to the chicks and collecting the uningested food from the burrow daily. Limited data were also gathered for Tufted and Horned puffins (Fratercula cirrhata and F. corniculata). Auklet chicks received an average of 34.1...

The complex variable boundary element method: Applications in determining approximative boundaries
T. V. Hromadka II
1984, Engineering Analysis (1) 218-222
The complex variable boundary element method (CVBEM) is used to determine approximation functions for boundary value problems of the Laplace equation such as occurs in potential theory. By determining an approximative boundary upon which the CVBEM approximator matches the desired constant (level curves) boundary conditions, the CVBEM is found to...
A comparison of iron oxide-rich joint coatings and rock chips as geochemical sampling media in exploration for disseminated gold deposits
W. Crone, L.T. Larson, R.H. Carpenter, T. T. Chao, R. F. Sanzolone
1984, Journal of Geochemical Exploration (20) 161-178
We evaluated the effectiveness of iron oxide-rich fracture coatings as a geochemical sampling medium for disseminated gold deposits, as compared with conventional lithogeochemical methods, for samples from the Pinson mine and Preble prospect in southeastern Humboldt County, Nevada. That disseminated gold mineralization is associated with Hg, As, and Sb is...
Chronobiologic approach to aquaculture
N. C. Parker
1984, Transactions of the American Fisheries Society (113) 545-552
Diel and seasonal changes in the environment directly or indirectly control many biological functions. Chronobiology, the study of biological functions in relation to time of day, time of year, lunar phases, and other consistent cues, could have important applications in aquaculture. Physiological conditions that vary seasonally include feeding time, tolerance...
Availability of water from the alluvial aquifer in part of the Green River Valley, King County, Washington
W. E. Lum II, R. C. Alvord, B. W. Drost
1984, Water-Resources Investigations Report 83-4178
The Muckleshoot Indian Tribe plans (1982) to build a fish hatchery in part of a 1.56-square-mile area in the Green River valley, Washington, and use groundwater to operate it. Groundwater data were collected in the area and used in a U.S. Geological Survey two-dimensional groundwater-flow model calibrated to simulate the...

Technological innovations in aquaculture
N. C. Parker
1984, Fisheries (9) 13-16
Technology in aquaculture has expanded at a phenomenal rate during the last 50 to 100 years. Based on both this past progress and the present technological advances being made in our society, it is reasonable to expect aquaculturists to profit from the rapid technological advances being made in both hardware...
Multilocus electrophoretic assessment of the genetic structure and diversity of Yersinia ruckeri
W. B. Schill, S.R. Phelps, S. W. Pyle
1984, Applied and Environmental Microbiology (48) 975-979
Multilocus isoenzyme electrophoresis was used to screen 47 field isolates of Yersinia ruckeri for electrophoretic variation at 15 enzyme loci. Only four electrophoretic types were observed, thus indicating that the genetic structure of Y. ruckeri is clonal. Forty-two isolates were of one electrophoretic type, a reflection of the low amount of genetic diversity extant...
A lymphosarcoma of thymic origin in the rainbow trout, Salmo gairdneri Richardson

1984, Journal of Fish Diseases (7) 73-82
A rainbow trout with a malignant lymphoma of probable thymic origin showed direct spread of the tumour to the gills, metastases to the liver and head kidney, and the presence of abnormal circulating lymphocytes. The cells of the tumour possessed plasma membrane immunoglobulin detectable by...
Geochemistry of a naturally occurring massive marine gas hydrate

During Deep Sea Drilling Project (DSDP) Leg 84 a core 1 m long and 6 cm in diameter of massive gas hydrate was unexpectedly recovered at Site 570 in upper slope sediment of the Middle America Trench offshore of Guatemala. This core contained only 5–7% sediment, the remainder being the...

Proper expression of metabolizable energy in avian energetics
M. R. Miller, K. J. Reinecke
1984, Condor (86) 396-400
We review metabolizable energy (ME) concepts and present evidence suggesting that the form of ME used for analyses of avian energetics can affect interpretation of results. Apparent ME (AME) is the most widely used measure of food energy available to birds. True ME (TME) differs from AME in recognizing fecal and urinary energy of nonfood origin as...

The U. S. Geological Survey (USGS) has been developing a program which would emphasize broad-scale surveys of the continental margin and intensive studies of 'baseline corridors' in various areas of the U. S. EEZ to gather energy and mining information in this new frontier as quickly as possible. Of twelve...
Isotope composition of sulphate in acid mine drainage as measure of bacterial oxidation
B.E. Taylor, M.C. Wheeler, D. Kirk Nordstrom
1984, Nature (308) 538-541
The formation of acid waters by oxidation of pyrite-bearing ore deposits, mine tailing piles, and coal measures is a complex biogeochemical process and is a serious environmental problem. We have studied the oxygen and sulphur isotope geochemistry of sulphides, sulphur, sulphate and water in the field and in experiments to...
Two new species of Myxozoa, Myxobolus inaequus sp. n. and Henneguya theca sp. n. from the brain of a South American knife fish, Eigemannia virescens (V.)
M.L. Kent, G. L. Hoffman
1984, Journal of Protozoology (31) 91-94
Two new species of Myxozoa from the brain of the green knife fish Eigemannia virescens are described: Myxobolus inaequus sp. n. has an unusually large spore body and extremely unequal polar capsules, and Henneguya theca sp. n. has an attenuated spore encased in a sheath not previously described in other Myxozoa. Only spores of the two...
