Relationship Between Metabolic Rate And Body Size In An Elasmobranch (Squalus Suckleyi) And In A Teleost (Ophiodon Elongatus), Austin W. Pritchard, Elisabeth Florey, Arthur W. Martin Jan 1958

Relationship Between Metabolic Rate And Body Size In An Elasmobranch (Squalus Suckleyi) And In A Teleost (Ophiodon Elongatus), Austin W. Pritchard, Elisabeth Florey, Arthur W. Martin

Journal of Marine Research

A method using polyethylene tubing of various sizes and a flow of water commensurate with the size of the specimen has been employed to determine the resting metabolic rates of large fish. With female dogfish, ranging in size from 0.1-9 kg, at about 13° C, there is a linear regression of log metabolic rate on log body weight with a slope calculated at 0.74. The metabolic rates of ling-cod, ranging in body weight from about 0.2-20 kg, gave a slope of 0.78.

Chemical Composition Of Three Manganese Nodules From The Pacific Ocean, J. P. Riley, Prapas Sinhaseni Jan 1958

Chemical Composition Of Three Manganese Nodules From The Pacific Ocean, J. P. Riley, Prapas Sinhaseni

Journal of Marine Research

Three manganese nodules from the Pacific Ocean have been analysed for 35 elements by using ma.inly spectrophotometric a.nd spectrogra.phic methods. Cu, Co, Ni, Zn, and Pb were found in amounts approaching 1 %, which far exceeds their average concentrations in igneous rocks. On the other hand, elements having readily hydrolysable ions, such as Ga, Sc, Zr, Y, La and Ti, are present only in amounts comparable with their concentrations in igneous rocks....

Effect Of Coriolis Force On Edge Waves (Ii) Specific Examples Of Free And Forced Waves, Kinjiro Kajiura Jan 1958

Effect Of Coriolis Force On Edge Waves (Ii) Specific Examples Of Free And Forced Waves, Kinjiro Kajiura

Journal of Marine Research

Modification of edge waves due to Coriolis force is examined in terms of two specific problems: dispersion of an initial deformation of the water surface; the forced wave due to a moving atmospheric pressure disturbance. In both cases the scale of the disturbance is an important factor, and the larger the scale the larger the effect of Coriolis force.

The Migration Of Adult Female Blue Crabs, Callinectes Sapidus Rathbun, In Chincoteague Bay And Adjacent Waters, David G. Cargo Jan 1958

The Migration Of Adult Female Blue Crabs, Callinectes Sapidus Rathbun, In Chincoteague Bay And Adjacent Waters, David G. Cargo

Journal of Marine Research

A total of 392 adult female blue crabs were tagged at four different points in the Chincoteague Bay area from 31 July to 7 September 1953. Over a period including June 1954, about 25% were recaptured, mostly to the south of the release points. Only three had moved northward, and only two were recaptured outside the area; one in Delaware Bay and one at Oyster, Virginia. Factors that may influence their movements and some ecological considerations are discussed.

Elliptical Polarization Of Submarine Illumination, Alexandre Ivanoff, Talbot H. Waterman Jan 1958

Elliptical Polarization Of Submarine Illumination, Alexandre Ivanoff, Talbot H. Waterman

Journal of Marine Research

Field and laboratory measurements have been made to extend our understanding of submarine elliptically polarized light, which occurs in lines of sight just beyond the critical angle. It is not detectable in bearings of the sun or anti-sun, is strongest within a few centimeters of the surface, is more easily observed with large solar zenith distances, and is not affected by light entering the water at the surface in the line of sight....

Inorganic Suspended Matter In Sea Water, Francis A.J. Armstrong Jan 1958

Inorganic Suspended Matter In Sea Water, Francis A.J. Armstrong

Journal of Marine Research

The suspended matter in sea water has been separated with membrane filters· (down to 0.1 µ A.P.D.); the inorganic fraction, determined by ignition, has been partly analysed. The methods used are briefly described. An appreciable quantity of finely divided claylike material was found, and it is suggested that, by adsorption of organic matter from the water, this may support the bacterial flora. Samples taken regularly from the English Channel show a seasonal variation...

Control Of Sedimentation And Bottom Configuration By Convection Currents, Lake Washington, Washington, Howard R. Gould, Thomas F. Budinger Jan 1958

Control Of Sedimentation And Bottom Configuration By Convection Currents, Lake Washington, Washington, Howard R. Gould, Thomas F. Budinger

Journal of Marine Research

Lake Washington near Seattle occupies a deep narrow trough sculptured by the Vashon ice sheet, the last continental glacier to invade the Seattle area. Extending along the center of the trough is a broad ridge that stands 5 to 30 feet above narrow valleys on either side. Thus, the trough in cross-section is W-shaped rather than U-shaped, as are most glacial valleys. The sediments in the trough consist of blue clay, locally more than 100 feet thick, overlain by limnic peat or gyttja 5 to 55 feet thick. The blue clay consists of rock flour of meltwater origin and the …

The Annual Cycle Of Phosphorus And Nitrogen In New England Coastal Waters, Bostwick H. Ketchum, Ralph F. Vaccaro, Nathaniel Corwin Jan 1958

The Annual Cycle Of Phosphorus And Nitrogen In New England Coastal Waters, Bostwick H. Ketchum, Ralph F. Vaccaro, Nathaniel Corwin

Journal of Marine Research

Distributions of phosphorus and nitrogen in New England coastal waters at various times of year are described. In surface waters the nitrate-nitrogen content is sometimes completely exhausted, even though small concentrations (0.2-0.5µg-at/l) of phosphorus are always available. The ratio of concentrations by atoms, N:P, varies in surface waters from maximum values of about 10: 1 to values approaching zero as the nitrate is exhausted....

Diurnal Study Of Phytoplankton Pigments: An In Situ Study In East Sound, Washington, Charles S. Yentsch, Robert F. Scagel

Journal of Marine Research

The effect of light intensity on the quantities of chlorophyll and carotenoid pigments in a natural marine diatom community has been observed. Marked daily fluctuations in the quantities of these pigments, which showed highest concentrations around mid-day and at night, resulted from changes in quantities within the cells. Rates of synthesis and decomposition throughout the day have been computed. Highest cellular concentrations of chlorophyll and carotenoid pigments corresponded to optimal light intensities for photosynthesis....
