TL;DR: In this article, the response of phytoplankton to nitrate and ammonia concentrations has been investigated using nitrogen-15 tracer techniques in the Bering Sea, the waters of southeastern Alaska, and the northeastern tropical Pacific.

TL;DR: The Subtropical Mode Water (SMW) as mentioned in this paper is a water type that is the same as the 18°C Water in the North Atlantic and is carried not only by the North Equatorial Current and eastward by the Kuroshio but also by the westward undercurrent which is often covered by the eastward Sub Tropical Countercurrent.

TL;DR: In this paper, it was shown that in regions of small bottom gradient the Stokes velocity is in the same direction as the phase velocity, but in the region of large bottom gradient it is reversed.

TL;DR: The solubility of argon in pure water and sea water has been measured over the temperature range 1·05-35°C, and up to a chlorinity of 21·5‰, using the method employed in the earlier parts of this series as discussed by the authors.

TL;DR: A mechanism for the formation of iodide in the ocean has been demonstrated by bacterial and enzymatic experiments as mentioned in this paper, and it is shown that Iodate can be reduced by those marine bacteria which are able to reduce nitrate and by extract from E. coli which contains nitrate reductase.

TL;DR: In this paper, it was shown that convective fingers can form not only in the salt-heat system, but also in a fluid containing two solutes with much closer diffusivities (for example sugar above a salt solution).

TL;DR: In this article, chemical and mineralogical analyses of manganese nodules from a large number of widely spaced localities in the Pacific and Indian Oceans have shown that their mineralogy and chemical composition varies both areally and with depth of formation.

TL;DR: In this article, the authors found that large epibenthic invertebrates in the deep-sea off North Carolina have restricted distributions which are narrow ribbons parallle to depth contours.

TL;DR: Foraminifera abundance in surface waters typically ranges from 1 or less to 100,000,000 specimens per 1000 m3, depending largely on the sampling gear used as mentioned in this paper.

TL;DR: In this article, the authors analyzed manganese nodules from different parts of the ocean floor for their uranium, thorium, protactinium, and radium contents.

TL;DR: In this article, a variation in the depth and the frequency of burrows within these deposits has been recognized and correlated over a distance of 65 km within Cascadia Channel, and it is postulated that turbidity flows create a unique environment in the channel and that the fauna is affected by differences in sediment size and composition and by the increased supply of utilizable organic material.

TL;DR: In this article, the Adriatic Sea and the eastern Mediterranean are considered from the standpoint of the interrelation between the smaller, more continental, basin and the larger, more maritime, basin.

TL;DR: In this paper, a correlation between the concentration of dissolved oxygen and δ 13C is observed at all stations below the top meters, due to the oxidation of organic matter depleted in 13C.

TL;DR: In this paper, an isopach map of unconsolidated sediments of the Indian Ocean is used to construct a map of the sediments in the area around the mid-oceanic ridge.

TL;DR: In this article, Tosa Terrace contains at least 1.5 km of terrestrially derived horizontally bedded sediments trapped by an outer structural dam in the Shikoku Basin.

TL;DR: In this article, a buoy system consisting of a moored thermistor chain has been developed to get a detailed picture of the wave trains and preceding internal fronts in the Strait of Gibraltar, and the recordings reveal that the internal (boundary) waves form definite wave trains consisting of 5-8 cycles, preceded by internal fronts.

TL;DR: In this article, vertical profiles of light scattering at 31 stations along the western margin of the North American Basin were used to establish the bottom nepheloid layer as a permanent (non-seasonal) feature of the bottom waters of this region in depths greater than 3000 m.

TL;DR: The U.S. Oceanographer, using a narrow beam echo sounder and satellite navigation, conducted a 1500 mile survey of the Mid-Oceanic Ridge at 35°N, 35°W in an area where the earthquake epicenter belt was offset as mentioned in this paper.

TL;DR: The lipids of one species of epipelagic euphausiid and six species of mesopelagic decapods from the eastern North Atlantic have been shown by thin-layer chromatography to consist mainly of triglyceride, with small amounts of mono- and di-glyceride, sterol, sterols ester and phospholipid as mentioned in this paper.

TL;DR: In this paper, the vertical profiles of steady and time-dependent horizontal ocean currents were defined using data collected from moored current meters at a single site (Site D) in the western North Atlantic.

TL;DR: In this paper, the distribution of MnO, Fe 2 O 3, Cu, Pb, Co, Ni, Cr and V is studied in eighteen samples of a North Pacific pelagic core.

TL;DR: In this article, the distribution of nitrate in the subarctic Northeast Pacific Ocean was studied and it was suggested that the maintenance of high nitrate concentrations over much of the area is due to relatively intensive entrainment of deep water into the upper zone coupled with a slow rate of removal of nitrates by the primary producers.

TL;DR: An analytic solution to the linear field equations in a Boussinesq, exponentially stratified fluid when an internal wave is incident upon a vertical, partial barrier is given in this paper.

TL;DR: In this article, free air gravity values averaged over 1°, 5° and 20° squares of latitude and longitude in the Indian Ocean were presented, and the accuracy of the data was assessed by comparing gravity values at intersections of ships' tracks and the 1° square averages for different cruises.

TL;DR: In this article, it was shown that small particles in the size range of 0·22-1·2 μ are important as nuclei in the formation of larger particles during the bubbling process and no evidence is found that bacteria are any more important in this process than non-living particles.

TL;DR: The larval characters of the genus Scyllarides are revised in the light of present findings as discussed by the authors, which fall into two groups according to the development of the fifth pereiopod.

TL;DR: In this paper, a paleomagnetic study of forty cores from the Indian Ocean has been completed, and the cores have been correlated using the stratigraphy obtained through a study of the inclination change in the cores rates of sedimentation range from 3 to 7 mm/1000 years in the deep ocean basins However, rates in excess of 20 mm /1000 years were recorded Recognizable hiatuses occur in about 32% of the cores studied.

TL;DR: In this paper, parachute drogues set at selected depths from the surface to 500 m during all seasons and in several years were used to measure the subsurface flow of 70 km off the Oregon coast.
