Transport of chloride ion in a water-unsaturated soil exhibiting anion exclusion
Ronald V. James, Jacob Rubin
1986, Soil Science Society of America Journal (50) 1142-1149
Miscible displacement techniques were used to create Cl- concentration profiles in unsaturated laboratory columns of Delhi sand (Typic Xeropsamments), each having a nearly uniform water content. The three steady flow rates used resulted in three different, average water contents. Chloride concentrations near the top of the column were smaller and...
Fish assemblages in Macrocystis and Nereocystis kelp forests off Central California
James L. Bodkin
1986, Fishery Bulletin (84) 799-808
The abundance and species composition of conspicuous fishes were compared within two canopy forming kelp forests (giant kelp, Macrocystis pyrifera, and bull kelp, Nereocystis luetkeana) in Central California. The primary investigative method was a subtidal belt transect, in which visual observation was used. The species composition of fish assemblages in the...
Digital image measurement of the area and anatomical structure of tree rings
Thomas M. Yanosky, Charles J. Robinove
1986, Canadian Journal of Botany (64) 2896-2902
A microcomputer coupled to a video digitizer was used to develop methods for measuring areas of tree rings and for delineating and measuring microscopic anatomical features. Digitally imaged areas of individual rings of a loblolly pine cross section were within 2.6% of areas measured with a planimeter and were more...
Influence of irrigation on salinity and nitrate in a stream-aquifer system
Leonard F. Konikow, M.A. Person
1986, Conference Paper, Conjunctive water use: understanding and managing surfacewater-groundwater interactions
Changes in salinity and nitrate concentration in groundwater and surface water in the semiarid Arkansas River valley of southeastern Colorado, USA were related primarily to irrigation practices. Water is applied to fields by flood irrigation through ditches and furrows. Irrigation water is derived in nearly equal amounts from surface water...
Application of the Flory-Huggins theory to the solubility of solids in glyceryl trioleate
Cary T. Chiou, Milton Manes
1986, Journal of the Chemical Society, Faraday Transactions I (82) 243-246
The conventional thermodynamic deviation for ideal solid–liquid solubilities is modified by substituting the Flory–Huggins model for Raoult's law. A comparison of published data for eleven solides in glyceryl trioleate with the predictions of the conventional and modified equations shows that the significantly higher athermal solubilities from the modified...
A sublittoral population of Pleurophycus gardneri Setchell and Saunders 1900 (Phaeophyceae: Laminariaceae) in central California
Glenn R. VanBlaricom, Daniel C. Reed, Christopher Harrold, James L. Bodkin
1986, Bulletin of the Southern California Academy of Sciences (85) 120-122
Published distributional records for the stipitate kelp Pleurophycus gardneri Setchell and Saunders 1900 (Phaeophyceae: Laminariaceae) indicae a geographic range from Montague Island (59°58’N, 147°22W), Alaska to Fort Bragg (39°27’N, 123°47’W), California (Druehl 1969, 1970; Kjeldsen 1972). P. gardneri is found primarily in rocky intertidal and shallow subtidal locations (Scagel 1967;...
Scale-dependent correlation of seabirds with schooling fish in a coastal ecosystem
Davod C. Schneider, John F. Piatt
1986, Marine Ecology Progress Series (32) 237-246
The distribution of piscivorous seabirds relative to schooling fish was investigated by repeated censusing of 2 intersecting transects in the Avalon Channel, which carries the Labrador Current southward along the east coast of Newfoundland. Murres (primarily common murres Uria aalge), Atlantic puffins Fratercula arctica, and schooling fish (primarily capelin Mallotus...
Inductively coupled plasma atomic fluorescence spectrometric determination of cadmium, copper, iron, lead, manganese and zinc
R. F. Sanzolone
1986, Journal of Analytical Atomic Spectrometry (1) 343-347
An inductively coupled plasma atomic fluorescence spectrometric method is described for the determination of six elements in a variety of geological materials. Sixteen reference materials are analysed by this technique to demonstrate its use in geochemical exploration. Samples are decomposed with nitric, hydrofluoric and hydrochloric acids, and the residue dissolved...
What won't Turnstones eat?
Robert E. Gill Jr.
1986, British Birds (79) 402-403
The Turnstone Arenaria interpres probably has one of the most varied diets of any wader species. Besides the 'normal' foods taken (see, e.g., Prater 1972, Nettleship 1973, Jones 1975), a considerable variety of 'unusual' foods and feeding behaviours has also been reported. Items taken include soap, gull excrement, dog food,...
Potentiometric map of the Meridian-Upper Wilcox aquifer in Mississippi, fall 1983
Daphne Darden
1986, Water-Resources Investigations Report 86-4018
The Meridian-upper Wilcox aquifer consists of the Meridian Sand member of the Tallahatta Formation and the uppermost sand beds of the Wilcox Group. Thickness of the aquifer ranges from 50 ft to 500 ft. Precipitation recharges the Meridian-upper Wilcox in the outcrop area, which extends from Benton County, MS, in...
Potentiometric surface of the Floridan aquifer system in the Suwannee River Water Management District, Florida, May 1985
Jack C. Rosenau, Paul E. Meadows
1986, Water-Resources Investigations Report 86-4184
The potentiometric surface map of the Floridan aquifer system in the Suwannee River Water Management District depicts the level to which water rose in tightly cased wells that tap the Floridan aquifer system in May 1985. The Floridan aquifer is the principal source of freshwater for north Florida. The surface...
