Showing papers in "Deep Sea Research and Oceanographic Abstracts in 1970"

TL;DR: In this paper, precise data on the solubilities of nitrogen, oxygen and argon in distilled water and seawater are fitted to thermodynamically consistent equations by the method of least squares.

TL;DR: In this paper, the authors considered a linear velocity field consisting of the rates of stretching deformation and shearing deformation, vorticity, and divergence (or negative convergence), and showed that a group of foreign particles initially arranged in a circle surrounding a singularity will be deformed into an ellipse.

TL;DR: In this article, a simple model of forcing by a wind stress was used to estimate the phase, amplitude and intermittency of bursts of inertial oscillations in the mixed layer.

TL;DR: In this paper, the titration alkalinity At and the total carbon dioxide concentration Σ CO2 of a sea water sample can be determined by direct potentiometric titration.

TL;DR: Eltanin et al. as discussed by the authors described the oceanographic features of the Ross Sea during the austral summer, based primarily upon observations taken aboard the U.S.N.S., which provided calibration data for electronically recorded in situ salinity-temperature-depth (STD) measurements.

TL;DR: The Norwegian Sea is considered as a typical Mediterranean basin for which an inflow of light, surface water is required to balance the overflow of deep, dense water formed by the action of the atmosphere at the sea surface within the basin this paper.

TL;DR: In this article, the basic stratification and the sloping boundaries of the ocean induce a mean upwelling velocity at the walls in order to satisfy the no flux condition, and the effect is confined to a boundary of thickness 0((vk)12/N12 where v, k are the austausch coefficients for momentum and heat respectively, and N is the local Brunt-Vaisala frequency.

TL;DR: In this article, it was shown theoretically and observed experimentally that spontaneous motions are set up in a stably stratified diffusive fluid in a container whose side-walls are not vertical, and the fluid streams up or down the inclined walls in a kind of boundary layer whose Reynolds number is inversely proportional to the Prandtl number.

TL;DR: In this article, a technique was developed for the determination of the 13 C/12 C ratios in the dissolved organic matter in the sea and the results suggest a singular and common source for the dissolved and particulate organic matter and that this material is stable to biochemical fractionation.

TL;DR: In this paper, solid phases from surface sediments, atmospheric dusts, and rivers of the Indian Ocean environment have been analyzed for their clay minerals and quartz, and the data have been used to delimit the transport paths and sources of the detrital minerals in the oceanic deposits.

TL;DR: The concentration of mineral grains, phytoliths, fresh-water diatoms, fungus spores and opaque spherules was measured in air and surface water samples collected during two crossings of the North Atlantic between Barbados-Gibraltar-Plymouth, U.K. and New York (September, 1965).

TL;DR: In this paper, the authors analyzed samples from 50 stations in the North Atlantic for particulate organic carbon and found that organic matter comprises about one third of the total mass of suspended matter.

TL;DR: In this article, organic particles greater than 5 μ from 38 North Atlantic stations were examined using phase microscopy and four morphological categories were evident: aggregates, flakes, fragments and unclassifiable particles.

TL;DR: In this paper, the upward sequential appearance of planktonic Foraminifera into three faunal zones was found to correlate with established radiolarian zones and paleomagnetic stratigraphy.

TL;DR: A survey of 1200 records of species and 33,200 individuals has shown that the hadal fauna is furthermore characterized by a composition which in several respects is different from the fauna of the neighbouring abyssal zone.

TL;DR: The position of the Gulf Stream between Cape Hatteras and approximately 60°W was delineated at intervals of a few days to a month using the 15°C isotherm at 200 m depth as an indicator for the thermal front associated with the stream as mentioned in this paper.

TL;DR: In this article, a mathematical expression for the relationship between specific gravity, salinity and temperature has been computed for natural sea waters covering the salinity range 9 − 41% at temperatures of 0 − 25°C.

TL;DR: A bloom of Trichodesmium erythraeum occurred in great profusion in the Laccadives and largely occupied the upper few meters of the water as mentioned in this paper.

TL;DR: In this paper, the results of continuous temperature-salinity measurements from stations west of Gibraltar are presented, and special features of the structure of the Mediterranean Water in relation to the corresponding turbulent mixing and salt-fingering process are discussed: the two maxima in the vertical profiles, the variation in time of small-scale phenomena, and the step-like structure at the lower boundary of Mediterranean Water.

TL;DR: In this article, the reference level, or level of no horizontal motion, may be at least as deep as 2300 m, instead of 1300 m as assumed previously. But the observed currents were in the range 2-7 cm/sec, and showed no clear evidence of being coherent with surface currents.

TL;DR: In this article, a numerical model is formulated to study the current and water mass properties of the Indian Ocean and its seasonal response to the monsoonal wind field, with particular emphasis on the investigation of the Somali Current and its season response.

TL;DR: The volume transport of bottom water in the western basin of the Atlantic Ocean has been determined by dynamic calculations for seven oceanographic sections made during the International Geophysical Year between 32°S and 16°N as discussed by the authors.

TL;DR: Menzel and Vaccaro as mentioned in this paper measured the dissolved organic carbon (DOC) in the water samples collected in the western North Pacific (44-25°N, 151°E) during the Ryofu-Maru cruise in June 1967.

TL;DR: In this article, the real response to wind stress variations appears to include local reinforcement of the return transport along the western boundary, suggesting that the variance in the pressure field must be included in a quantitative description of the mean wind stress field, but not in a qualitative one.

TL;DR: In this paper, the authors made measurements of ocean currents in the Western Mediterranean Sea at five depths for two months during early 1969 and found a dominant and persistent presence of inertial oscillations, that is, of circularly polarized currents having periods of a half pendulum day.

TL;DR: In this paper, bottom currents have significantly influenced the sediment distribution pattern in an abyssal hills region of the central equatorial Pacific, and the mean direction of flow of bottom water there has persisted for a considerable period of time, perhaps for much of the Tertiary.

TL;DR: McIntyre et al. as discussed by the authors found a phyletic link between Coccolithus huxleyi and the Gephyrocapsa complex using a coccolith from the upper Pleistocene of the Atlantic.
