Showing papers in "Deep Sea Research in 1959"

TL;DR: In this article, a treatment of stationary planetary flow patterns driven by source-sink distributions in a cylindrical tank is extended to predict flow patterns which might be expected under similar circumstances on a rotating sphere.

TL;DR: In this article, the authors constructed a highly idealized model of the general abyssal circulation of the world ocean based on the postulation of the existence of two concentrated sources of abyssal waters (one in the North Atlantic and another in the Weddell Sea).

TL;DR: Gross and net primary production have been measured at bi-weekly intervals for 18 months in the Northwestern Sargasso Sea 15 miles SE of Bermuda in 1500 fm of water.

TL;DR: The hadal fauna is certainly derived from the abyssal zone, and probably all crustacean groups living at great depths a remarkable gigantism has been found, probably due to the effect of the hydrostatic pressure on the metabolism.

TL;DR: Direct measurements made along the equator in the central and eastern tropical Pacific during the IGY show that the subsurface eastward flow, first described in 1954, is a fast, thin, but major current as discussed by the authors.

TL;DR: In this paper, it was shown that a linear theory constructed from Ekman spiral and geostrophic current does not suffer singularities at the equator and exhibits some qualitative similarity to the Equatorial Undercurrent, but that in order to account for the observed amplitude of the phenomenon, non-linearities are not altogether negligible.

TL;DR: The quantity of phytoplankton, computed as number of cells under 0·1 m 2 , was found to be much the same as the maximal figure for the Sargasso Sea and the amount obtained before and after the time of maximal population in the antarctic and subantarctic Pacific.

TL;DR: In this paper, it is shown by a dimensional argument that for the range of parameters applicable to the Cromwell Current, the inertial forces are equally important with the frictional forces.

TL;DR: The relationship between the communities of bottom invertebrates and recent geological processes described for the Kurile-Kamchatka Trench are to be expected in all other deep ocean depressions under similar conditions.

TL;DR: A median valley of the Mid-Atlantic Ridge at least 75 miles in length running in a North-South direction is described in this article, where the bottom lies at a depth between 1800 and 2200 fm and the flanks rise steeply to between 900 and 1200 fm.

TL;DR: In this article, a simple relation between the east-west pressure gradient and the curvature of the velocity profile yields an undercurrent, but application is uncertain because of neglect of accelerations.

TL;DR: The distribution of a planktonic worm, Poeobius meseres Heath, was determined from an examination of over 1800 quantitative plankton tows taken in the North and South Pacific, and this distribution is compared with the distribution of water masses, as defined by temperature-salinity curves.

TL;DR: In this paper, deep current measurements extending over several weeks were made in a small area of the Eastern North Atlantic during the summer of 1958, and a number of hydrographic stations were occupied in the same area.

TL;DR: In this paper, an approximation valid near the equator was developed for a model of the general thermal circulation, and the existence of equatorial effects is related to the vanishing of the Coriolis parameter.

TL;DR: Ovotestes, with both male and female components in advanced stages of maturation, were found in ten species of the iniomous familes Chlorophthalmidae, Bathypteroidae, Alepisauridae and Paralepididae.

TL;DR: In this paper, the authors investigated the Indian Ocean water masses at 61 stations along the sections between Africa and the Antarctic, the Antarctic and Asia, showed that Antarctic waters are characterized by low concentrations of heterotrophs (which assimilate only easily accessible forms of organic substance), whereas the equatorial-tropical waters were characterized by high concentrations of these micro-organisms.

TL;DR: In this paper, an Antarctic Ocean deep-sea core from the Ross Sea can be correlated with three others from the same area, dated by Urry and described by Hough (1950), all the cores showed several alternations of glacial marine sediment and of fine-grained sediment which is apparently nonglacial.

TL;DR: An adaptation of the sound pinger designed by Edgerton to position an underwater camera for bottom photography has been used to monitor bottom coring operations with a Stetson corer as mentioned in this paper.

TL;DR: The Marine Antarctic Expedition of the U.S. Geological Survey (MAGES) as discussed by the authors was the first oceanographic work in sub-surface geology, especially work in submarine geology in the Antarctic and in the Indian Ocean.

TL;DR: In this article, a method of using micro-organisms as hydrological indicators has been shown: investigation of areas of microbial forms with perculiar morphological characteristics makes it possible to determine the origin of water masses.

TL;DR: In this paper, the topography of the sea floor near the heads of the Ganges and Indus Submarine Canyons is described and details of the seafloor topology are shown.
