Knipovich, Nikolai Mikhailovich

(b. Suomenlinna, Finland, 25 March 1862; d. Leningrad, U.S.S.R., 23 February 1939)

marine biology, marine hydrology.

In 1886 Knipovich graduated from the Physics and Mathematics Faculty of St.Petersburg University. A year earlier he was a member of O. A. Grimm’s expedition to the Lower Volga to evaluate the long-range prospects for herring fishery in the Volga—Caspian basin. This experience aroused his interest in hydrology and the study of marine life, thereby defining the subjects of his subsequent scientific activity.

Beginning in 1887 Knipovich studied the biology of the White Sea. Soon his work expanded to the Barents Sea, where he organized and headed the Murmansk expedition for research on natural resources (1898-1901). This expedition, which was carried out on the Andrey Pervozvanny, the first vessel especially constructed for such work, brought back the first substantial information on the nature and rich natural resources of the northern seas of European Russia. Knipovich organized three Caspian expeditions for research on natural resources (1904, 1912-1913, and 1914-1915). The expeditions made it possible to present in great detail the peculiar hydrological features of the Caspian Sea and the distribution and annual cycle of marine life. In 1921 Knipovich summarized and published the results of the Caspian expeditions. They provided the basis for the subsequent regulation of commerce and the protection of the resource of the Caspian Sea. From 1905 to 1911 Knipovich organized and led research expeditions on the natural resources of the Baltic Sea. After processing the results of the third Caspian expedition, he led similar expeditions to the Sea of Azov and the eastern part of the Black Sea (1922-1927). In 1931-1932 he headed a research expedition to study the natural resources of teh entire Caspian Sea.

Before Knipovich, such research expeditions ot the Russian seas merely described the objects of possible commercial exploitation, without considering the water’s influence on them. Lnipovich was a pioneer in the study of marine fishes and their close connection with hydrological conditions. “Productivity of reservoirs,” he wrote in Gidrologia morey i solonovatykh vod (1938). “is always restricted by certain limits which ae determined by the aggregate of the physical and chemical conditions.…” Knipovich’s half-century of work is summed up in the same work: “As there is no scienitific hydrobiology without calculation of hydrological conditions, there is no scienitific hydrology without calculation of biological factors.”

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
