Gerold Siedler (born August 16, 1933) is a German physical oceanographer. He is professor emeritus at the Christian-Albrechts University of Kiel and at the GEOMAR Helmholtz Centre for Ocean Research Kiel.




Early life


Gerold Siedler was born in Olmütz (Czech: Olomouc), then Czechoslovakia. His movements during his childhood were influenced by the turmoil of World War II, until his family was finally reunited in 1946 in Plön, Schleswig-Holstein, West Germany. He attended schools in Reichenberg (now Liberec) and Prague during the war, and Weimar after. He completed his secondary education (German: Abitur) in 1953 at the Gymnasium Schloss Plön.




Professional positions and research


In 1953 Gerold Siedler started his studies in Physics, Mathematics and Geophysics at the Christian-Albrechts University of Kiel. He earned a doctoral degree in Physics in 1960 working with the applied physicist Werner Kroebel. His dissertation in the field of acoustics led him to develop a vocoder and explore speech discrimination in a reduced speech signal environment. Under the mentorship of Günter Dietrich, he subsequently started his career as a physical oceanographer at the Institute of Marine Science (German: Institut für Meereskunde Kiel, now GEOMAR Helmholtz Centre for Ocean Research Kiel), where he remained until retirement in 1998. He obtained his habilitation in oceanography and geophysics from the University of Kiel in 1966 for his work on the circulation and stratification at Bab-el-Mandeb, Red Sea.
He was appointed in 1969 as professor of physical oceanography at the same university. During his tenure at the Institut für Meereskunde and as professor of the University of Kiel, he held the following positions:

Director of Marine Physics Department, 1969-1998
Director of the Institut für Meereskunde, 1976-1978
Dean of the Faculty of Mathematics and Natural Sciences of the University of Kiel, 1991-1992
Emeritus Professor, since 1998
His work contributed in advancing knowledge on ocean circulation and climate, boundary currents, oceanic fronts, flow through straits, mixing processes, and internal waves. In addition, he was actively involved in the development of oceanographic instruments.
Siedler undertook 28 research expeditions, most of them as chief scientist. He spent time on the German vessel RV Meteor II (1964), and helped in the design of its successor, the RV Meteor III (1986). He played a fundamental role in designing the World Ocean Circulation Experiment (WOCE) program including defining standards for oceanographic sampling, which were pivotal for the success of the program. At the culmination of the WOCE, he co-edited the first edition of the "Ocean Circulation and Climate: Observing and Modelling the Global Ocean" book published in 2001, and subsequently its second edition "Ocean Circulation and Climate: A 21st Century Perspective" in 2013.
Over the years, Siedler held several positions as visiting scientist in the USA, France, Spain and South Africa. Most notably, he collaborated with scientists at the Woods Hole Oceanographic Institution, the University of Hawaii, the University of Miami and NOAA/AOML, the Jet Propulsion Laboratory in Pasadena, Université Pierre et Marie Curie, IFREMER in Brest, Instituto Canario de Ciencias Marinas, and the University of Cape Town.




Teaching


As a Privatdozent and subsequently a professor at the University of Kiel, Gerold Siedler taught since 1966. He additionally held appointments as visiting professor at Woods Hole Oceanographic Institution/Massachusetts Institute of Technology (USA), at the International Centre for Theoretical Physics (Trieste, Italy), the University of Hamburg (Germany), the Universidad de Las Palmas de Gran Canaria (Gran Canaria, Spain), Universidad de La Laguna (Tenerife, Spain), and the University of Concepción (Chile). He supervised the scholarly works of no less than 70 Diplom, Doctoral, and Habilitation students in Kiel.
