TL;DR: In this paper, the solubility coefficients for carbon dioxide in water and seawater are calculated for the data of Murray and Riley, and are fitted to equations in temperature and salinity of the form used previously to fit solubilities of other gases.

TL;DR: In this article, organic-rich sediments and coexisting phosphorites from the continental shelf off South West Africa have been analysed for uranium and thiorum by alpha-spectrometry.

TL;DR: A method for collection of surface films on the sea has been developed and tested at various places along the Swedish West Coast as discussed by the authors, and significant amounts of lipids were found even when no seaslicks were observed, and there are characteristic deviations in the fatty acid patterns compared to the corresponding lipids dissolved in the sub-surface water.

TL;DR: A colorimetric method was developed for determining molybdenum in seawater by solvent extraction of its dithiolate and was then applied during a nine month study of Saanich Inlet.

TL;DR: In this paper, the concentrations of the trace metals have been established in the open-ocean waters, and have been used as "baselines" to evaluate trace-metal enhancement in near-shore regions.

TL;DR: In this article, the authors used fluorescence spectroscopy to estimate the concentration of petroleum hydrocarbons in seawater from the general region between Nova Scotia and Bermuda and found that the distribution of oil is quite patchy, especially in surface waters.

TL;DR: In this article, a mesh technique was used to collect soil-sized marine particulates from the lower troposphere of the North, Equatorial and South Atlantic Ocean, northern and southern Indian Ocean, South and East China Sea and various coastal localities.

TL;DR: The solubility of amorphous silica in seawater at 0°C and from 1 to 1,220 atm. was found to be a linear function of pressure above 270 atm, but to deviate from linearity below that pressure.

TL;DR: In this article, the authors described modified forms of the iodate and total iodine methods described by Barkley and Thompson (1960), a spectrophotometric procedure for iodate determination derived from Johannesson's (1958) work, and an automatic method for total iodine determination.

TL;DR: Detailed analysis of the lipids present in seawater medium before and after growing cultures of the diatom Chaetoceros simplex calcitrans Paulsen in them has been carried out and compared with thelipids found in the diatoms itself.

TL;DR: In this article, the authors presented data for the concentrations of organic carbon and nitrogen, and C:N ratios, in marine particulate matter, and for POC and PN, from surface waters collected in the northeastern Atlantic, South Atlantic, Indian Ocean and China Sea.

TL;DR: In this paper, the vertical distribution of water-soluble sulfide has been determined in eight sediment cores from Montsweag Bay, Maine, using a conservative estimated mean of 5 moles sulfide/m 3 -mud, and a mixing ratio of less than 30 volumes of oxygen saturated seawater per volume of mud will render the water anoxic.

TL;DR: In this article, the authors used coprecipitation of chromium from sea water with hydrous iron oxides, followed by ion-exchange separation and isotope dilution mass spectrometry.

TL;DR: Deuterium values obtained for humic acids isolated from marine sediments from the NE Pacific are in the range of δ D = (−105 ± 5) ǫ, corresponding to values for marine plankton from the same area as mentioned in this paper.

TL;DR: In this paper, total-mercury analyses of seawater samples, collected from the surface down to 5,700 m depth in the northeastern Pacific Ocean and in the South Polar seas, showed a homogeneous distribution of mercury with depth at all stations, although its absolute concentration was 3 to 5 times less than that in the polar waters (50-150 ng/kg).

TL;DR: In this paper, partial equivalent conductances and partial equivalent volumes of the major constituents in seawater were used to evaluate the specific gravity-conductivity-chlorinity-salinity relationships in the marine environment.

TL;DR: In this article, the conditional stability of HSO 4 − has been determined at 25°C, 1 atm and a formal ionic strength of 0.7 M in solutions containing sodium, magnesium, chloride and sulphate.

TL;DR: In this article, the concentrations of particulate silica and inorganic suspended matter in the surface water of the North Pacific were determined, and it was shown that the particulate particles in the sea are mainly of biogenic origin.

TL;DR: In this paper, it was shown that sulfide disturbs the determination of nitrite by the Shinn method, and this disturbance can be counteracted by addition of an excess of Cd 2+ or Hg 2+ · Fe 2+ was also tried out, but in this case the results were not satisfactory.

TL;DR: In this article, a general equation for predicting the partial molal volume (pmv) of an electrolyte in seawater, using binary solution data, and seawater density data, is derived.

TL;DR: In this article, a method for producing a fistula in oysters by means of which materials may be administered, and samples of pallial fluid removed, without the stress to the animal attendant to forcible opening of the valves or boring of temporary holes.
