TL;DR: In this article, the concentration of chlorophyll and phaeophytin was measured in 85% acetone extracts using a sensitive fluorometer. The method is very sensitive in the 10 fluorescence units are equal to 0·001 O.D. 665 mμ 10 cm.

TL;DR: In this article, it was shown that wave-induced bubbles and surface circulation may constitute important mechanisms for production of organic particles in the ocean, and that adding these particles to filtered sea water decreased the apparent inorganic phosphate content of the sea water.

TL;DR: In this article, the authors used artificial enrichment of sea water to define nutrients critically limiting the growth of phytoplankton in the Sargasso Sea and found that the final population resulting from enrichment in terms of species composition was a function of the addition of specific nutrients.

TL;DR: In this article, a modification of earlier methods for the determination of the weight of suspended matter in 0·5 to 51.5 µm of sea water is presented, where filter pore size can be selected to meet the requirements of the experiment.

TL;DR: In this article, a model of wind-driven ocean circulation in a two dimensional homogeneous ocean is constructed in which Rossby waves occur in the northern portion of the basin, and it is shown that damped, stationary Rossby wave can occur in this model superimposed on a steady west to east flow.

TL;DR: A recording current mater for use in the deep ocean and a moored buoy station on which it may be located are described in this paper, where the station may be left unattended for extended periods of time.

TL;DR: In this paper, an investigation was carried out to examine the possibility that plankton production in Australian waters might be limited by the availability of nitrate, phosphate or iron, and the results showed a significant increase in CO2 uptake over unenriched controls, when enriched with iron, or iron together with either nitrate or phosphate.

TL;DR: A shipboard survey of the continental slope region between Mexico and California was conducted in 1961 and 1962 as mentioned in this paper, showing that it can be divided into three segments, whose boundaries are in line with the landward projections of the Murray Escarpment and the Cedros Escarpments on the deep-sea floor.

TL;DR: In this paper, a series of terraces that encircle the top of the Great Meteor Seamount (30° 00′N. Latitude, 28° 30′W. Longitude) was surveyed on two recent cruises of the Woods Hole Oceanographic Institution.

TL;DR: The magnetization of sediment from the eastern basin of the North Atlantic Ocean is due to magnetite and the variation of the directions of magnetization due in cores from the abyssal plains depends upon the sedimentary features which are the result of turbidity current deposition as discussed by the authors.

TL;DR: In this article, the authors compared the methods of Wooster and Rakestraw (1951) and Murphy and Riley (1962) for phosphate analysis in sea water, and found the former to have a small, systematic positive error associated with the use of distilled water for the reagent blank (a ‘hidden blank’ according to Jones and Spencer (1963)).

TL;DR: In this article, it was shown that the velocities in the core of the Equatorial Undercurrent do not agree with those calculated from the pressure gradient according to Bernoulli's equation; thus it seems that friction is important in establishing the velocity distribution.

TL;DR: During cruise 26 of the R/V Chain, Woods Hole Oceanographic Institution, several bathypelagic collections were made using closing gear and depth telemeter equipment developed by the National Institute of Oceanography in Great Britain, and the Isaacs-Kidd midwater trawl as discussed by the authors.

TL;DR: In this article, the principal mineral is francolite, which is found as bone, nodules and irregular masses with conglomeratic, laminated and dendritic internal structures.

TL;DR: In this article, the effect of hydrostatic pressure on the dissociation constants of carbonic acid and on the solubility product of calcium carbonate was used for estimating the in situ pH of calcareous sediments.

TL;DR: In this article, the mean, annual global irradiance was 9 cal/cm 2 /day and the total net irradiance were measured during 1960 and 1961 at ocean station "PAPA" (lat. 50°N, long 145°W).

TL;DR: In this article, an improved model of the so-called bathysonde is proposed to record temperature, conductivity, and pressure with high accuracy in great depths, and problems arise when evaluating electrical conductivity and temperature from in situ measurements.

TL;DR: The power spectra of hourly current speed readings from two Richardson current meters show a concentration of energy into long-period motions, as well as energy density peaks at the semi-diurnal tidal period and at the inertial period corresponding to the latitude of the current meter.

TL;DR: In this paper, a simple and direct method for measuring ocean currents is given by providing an identifiable point in the water and determining its displacement in a known time interval, where the speed is obtained by dividing the displacement by the time, and the direction of the velocity is the directions of the displacement.

TL;DR: In this article, a diagram and a description of the latitudinal physical geographic zonation of the world ocean is presented, which is useful for reckoning the commercial biological resources of the oceans, for transplantation and acclimatization of marine organisms, and for building a general picture of the natural zonations of the Earth.

TL;DR: In this paper, the Nansen bottle is fitted with a collar that holds a sterile bulb which is collapsed and plugged, and the plug is loosely connected to the hydrographic wire with a chain and hook.

TL;DR: In this paper, data from six surveys of the region off the Cape of Good Hope and one in the Benguela Current have been used to calculate dynamic height anomalies and surface currents.
