On the application of the units of measurement of the amount and composition of matter in oceanology
We consider the procedures of conversion of the conventional and out-of-system units of measurement of the amount and composition of matter used in oceanology to the International System of Units (SI). The coefficients of conversion are presented in the form of a table. We present the data on the units of measurement of mineralization (scales of salinity) of seawater for the oceanic range of its variability, freshened waters of internal seas, and brines. The contemporary concept of salinity as a dimensionless quantity is discussed.Translated from Morskoi Gidrofizicheskii Zhurnal, No. 4, pp. 61–72, July–August, 2004. 相似文献

A brief survey of the thirty-year history of creation and development of hydrologic probes at the Marine Hydrophysical Institute
of the Ukrainian Academy of Sciences is given. We describe problems arisen before developers and analyze the principles of
design of equipment, algorithmic support, software for data processing, and methodological and metrological support. The results
of intercalibration and application of probes in expeditions are presented.

On the basis of the generalization of the concept of standard ocean to the Black Sea, we deduce practical formulas for the conversion of pressure into depth and vice versa depending on the latitude of the place with regard for the equation of state for 1980. The error of these relations for the standard Black Sea (whose salinity is equal to 22.2 at a temperature of +9°C from the surface to the bottom) does not exceed ±0.2m and ±0.2dbar. The difference between the practical and actual depths in winter and summer periods does not exceed ±0.35m for depths varying within range 0–2000m. The proposed practical formulas enable one to simplify the procedure of rapid evaluation of depth (or pressure) in real time by excluding the procedure of integration over a specific volume. 相似文献

By using the relationships between the measurement error of hydrostatic CTD sea-level meters, the errors of measuring channels of hydrostatic pressure, temperature, and conductivity, and the errors
of determination of the gravitational acceleration, we estimate the admissible measurement errors for separate channels. Simplified
relations for the evaluation of salinity and density of water corresponding to the class of accuracy of the level meter are
presented. Possible differences between the readings of the level meters mounted at coastal level-measuring posts and the
actual sea level in the coastal zone caused by the weak water exchange in the sea-well system are estimated.
