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. [1]

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  [ de ].

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  [ de ]. His dissertation in the field of acoustics led him to develop a vocoder and explore speech discrimination in a reduced speech signal environment. [2] 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. [2]

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: [2]

His work contributed in advancing knowledge on ocean circulation and climate, boundary currents, oceanic fronts, flow through straits, mixing processes, and internal waves. [4] In addition, he was actively involved in the development of oceanographic instruments.

Siedler undertook 28 research expeditions, most of them as chief scientist. [2] [5] He spent time on the German vessel RV Meteor II (1964), [6] [7] 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, [8] and subsequently its second edition "Ocean Circulation and Climate: A 21st Century Perspective" in 2013. [9] [10] [11]

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  [ es ], and the University of Cape Town. [2]

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. [2]

The Helmholtz Association of German Research Centres is the largest scientific organisation in Germany. It is a union of 18 scientific-technical and biological-medical research centers. The official mission of the Association is "solving the grand challenges of science, society and industry". Scientists at Helmholtz therefore focus research on complex systems which affect human life and the environment. The namesake of the association is the German physiologist and physicist Hermann von Helmholtz.

The Surface Ocean Lower Atmosphere Study (SOLAS) is a global and multidisciplinary research project dedicated to understanding the key biogeochemical-physical interactions and feedbacks between the ocean and the atmosphere. Further, SOLAS seeks to link ocean-atmosphere interactions with climate and people. Achievements of these goals are essential in order to understand and quantify the role that ocean-atmosphere interactions play in the regulation of climate and global change.

The World Ocean Circulation Experiment (WOCE) was a component of the international World Climate Research Program, and aimed to establish the role of the World Ocean in the Earth's climate system. WOCE's field phase ran between 1990 and 1998, and was followed by an analysis and modeling phase that ran until 2002. When the WOCE was conceived, there were three main motivations for its creation. The first of these is the inadequate coverage of the World Ocean, specifically in the Southern Hemisphere. Data was also much more sparse during the winter months than the summer months, and there was—and still is to some extent—a critical need for data covering all seasons. Secondly, the data that did exist was not initially collected for studying ocean circulation and was not well suited for model comparison. Lastly, there were concerns involving the accuracy and reliability of some measurements. The WOCE was meant to address these problems by providing new data collected in ways designed to "meet the needs of global circulation models for climate prediction."
