Günter Dietrich

From Wikipedia, the free encyclopedia

Günter Dietrich (November 15, 1911 – October 2, 1972) was a German oceanographer. He was the first to describe the Agulhas Current in detail, he provided essential contributions to the understanding of bottom water exchange in the North Atlantic and he shaped marine research in Germany after World War II.

Early life and academic work

[edit]

Günter Dietrich was born in Berlin. From 1931 to 1935 he studied geography, meteorology, mathematics, physics and oceanography at the Friedrich-Wilhelms-Universität zu Berlin (see Humboldt University of Berlin). He received his Doctor of Philosophy in 1935.[Ref 1] with a dissertation on the structure and dynamics of the Agulhas Current.[Bib 1] His advisor was Albert Defant.[Ref 2] This work provided the first detailed description of the Agulhas Current System, based on observational data available at the time. The South African oceanographer Johann Lutjeharms later called him "the first true oceanographer of the Agulhas Current System" in his book on the Agulhas Current[Ref 3] [Ref 4]

From 1935 to 1943 he was scientific assistant at the de:Museum für Meereskunde (Berlin) (Institute and Museum for Oceanography) and participated in four cruises on the German survey ship Meteor in the North Atlantic and the Caribbean Sea.[Ref 1][Ref 5] He was drafted into the German Navy during World War II (WWII) and served as oceanographer at the Naval Observatory in Wilhelmshaven and Greifswald. He was in charge of 12 cruises on the navy survey ships "Triton" and "Börgen" in the Baltic Sea and off Norway.[Bib 2][Ref 6] The tasks included investigations of sound propagation, tides and tidal currents. During WWII he was able to obtain his habilitation (permission to teach) for geophysics and oceanography in 1943 at Berlin University with a thesis on semidiurnal and diurnal tides [Bib 3] and was appointed custodian at the Institute for Oceanography in Berlin. After the end of WWII and some time as prisoner of war, he was employed by the British Navy occupying forces, partly at their headquarters in Hamburg-Blankenese, from April 1946 to August 1950.[Bib 2] He also ran an engineering consultancy on oceanographic instrumentation during part of the time.[Ref 1] In 1950 he became a member of the German Hydrographic Office (DHI) in Hamburg (see Federal Maritime and Hydrographic Agency of Germany). He was responsible for regional oceanography and participated in several cruises on the survey and research vessels "Gauss" and "Anton Dohrn". He also became a lecturer in oceanography at Hamburg University in 1953 and adjunct professor in 1957 [Ref 1] [Bib 2]

In 1959 he became the successor of Georg Wüst in Kiel. He was appointed Professor of Oceanography and Maritime Meteorology at the Christian Albrecht University in Kiel (see University of Kiel) and Director of the Institut für Meereskunde Kiel (see [3]) of Kiel University [Ref 7][Ref 8][Ref 9][Ref 10]. Under his direction the institute increased considerably, international relationships were renewed [Ref 11] [Ref 12] and Kiel University became the prime institution for marine sciences education in Germany. His textbook [Bib 4] [Bib 5] [Bib 6] was the standard reading for students. Dietrich also carried outstanding responsibility in planning the new research vessel "Meteor" [4]. The ship was put into service in 1964 and had its first major cruise in the International Indian Ocean Expedition in 1964/1965. Dietrich later had major responsibilities in planning and preparing the multi-national ICES expedition OVERFLOW 1973. He died in Kiel, aged 60, a few months before the start of the program.

The main topics in Dietrich's 149 publications [Ref 13] are: the dynamics of ocean currents, the stratification and mixing of water masses and their variability, the morphology of the ocean's bottom and the influence of topography on the spreading of water masses, and sound propagation in the ocean. During the work for his doctoral dissertation on the Agulhas Current System [Bib 1] he was able to use data sets from the "Meteor" Expedition 1925-1927 [Ref 14] and additional data from some other ships. For the first time the Agulhas Current System was described also in deep layers.[Ref 4] He also compared the properties of the Agulhas Current and the Gulf Stream[Bib 7] and described the Agulhas Current as a branch of the Atlantic circulation.[Bib 8] He remained interested in the Gulf Stream, in particular in the relationship of pressure fields and currents [Bib 9] [Bib 10] and the origin of Gulf Stream water masses.[Bib 11] With geography as an essential field in his education, he kept returning to morphological studies [Bib 12] [Bib 13] [Bib 14] [Bib 15] and to the relationship of topography and bottom water flow.[Bib 16][Bib 17] He contributed considerably to the knowledge on the transport, distribution and mixing of water masses in the North Atlantic, the North Sea, the Baltic Sea and the Mediterranean. A selection of papers is cited here.[Bib 18][Bib 19][Bib 20][Bib 21][Bib 22][Bib 23][Bib 24][Bib 25][Bib 26][Bib 27] The hydrographic atlas of the northern North Atlantic, produced on behalf of ICES, became an important collection of observational results.[Bib 28] Following his work on semidiurnal and diurnal tides,[Bib 3][Bib 29][Bib 30] he became a respected expert on tides in the open ocean. During a time when the tides in the open ocean had to be determined solely from coastal gauges, his tidal maps were considered a standard in the field.[Bib 4] Dietrich was always prepared to use an holistic approach in marine research. He was interested in interdisciplinary problems, in particular the interactions between bottom topography and fisheries hydrography[Bib 31][Bib 32][Bib 33] In his textbook [Bib 4] [Bib 5] [Bib 6] he frequently discussed relations between the results of different disciplines.

Family
