Dendrochronology is the scientific method of dating tree rings to the exact year they were formed. As well as dating them this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek dendron (δένδρον), meaning "tree", khronos (χρόνος), meaning "time", and -logia (-λογία), "the study of".

Marie Tharp was an American geologist and oceanographic cartographer who, in partnership with Bruce Heezen, created the first scientific map of the Atlantic Ocean floor. Tharp's work revealed the detailed topography and multi-dimensional geographical landscape of the ocean bottom. Her work also revealed the presence of a continuous rift valley along the axis of the Mid-Atlantic Ridge, causing a paradigm shift in earth science that led to acceptance of the theories of plate tectonics and continental drift.
The quantitative revolution (QR)[n] was a paradigm shift that sought to develop a more rigorous and systematic methodology for the discipline of geography. It came as a response to the inadequacy of regional geography to explain general spatial dynamics. The main claim for the quantitative revolution is that it led to a shift from a descriptive (idiographic) geography to an empirical law-making (nomothetic) geography. The quantitative revolution occurred during the 1950s and 1960s and marked a rapid change in the method behind geographical research, from regional geography into a spatial science.

Henri Grissino-Mayer was a tenured faculty member in the department of Geography at the University of Tennessee, Knoxville who resigned in lieu of termination on Oct. 1st, 2018 due to his own admission of sexual misconduct at the school.
Ronald John Johnston, OBE, FAcSS, FBA was a British geographer, known for elaborating his discipline's foundations, particularly its history and nature, and for his contributions to urban social geography and electoral geography. His broad scope is illustrated by the fact that he made extensive use of quantitative methods, while critically dealing with subjects of social and political relevance. Johnston authored or co-authored more than 50 books and 800 papers, and edited or co-edited a further more than 40 books. He edited The Dictionary of Human Geography and for the first four editions was its main editor.

Ron Shamir is an Israeli professor of computer science known for his work in graph theory and in computational biology. He holds the Raymond and Beverly Sackler Chair in Bioinformatics, and is the founder and head of the Edmond J. Safra Center for Bioinformatics at Tel Aviv University.
Anthony Leiserowitz is a human geographer at Yale University who studies public perceptions of climate change. He has particularly examined perceptions within the United States, where people are considerably less aware of climate change than in other countries. In the U.S., awareness of information about climate change is heavily influenced by emotion, imagery, associations, and values; public discourse reflects a lack of understanding of the science involved in climate change, and little awareness of the potential for effective responses to it.
Gad Menahem Landau is an Israeli computer scientist noted for his contributions to combinatorial pattern matching and string algorithms and is the founding department chair of the Computer Science Department at the University of Haifa.
Thomas Thorstein Veblen is an American forest ecologist and physical geographer known for his work on the ecology of Nothofagus forests in the Southern Hemisphere and on the ecology of conifer forests in the southern Rocky Mountains of the U.S.A. He is an Arts and Sciences College Professor of Distinction at University of Colorado at Boulder, USA (2006).
Adrian J. Bailey is a scholar known for his research in population, migration, economic, and social geography. He is currently Chair Professor of Geography and Dean of Social Sciences at Hong Kong Baptist University. His research interests include the study of transnationalism, with his work in this area exploring the diverse ways in which the state affects life outcomes among immigrants and refugees.
Milos V. Novotny is an American chemist, currently the Distinguished Professor Emeritus and Director of the Novotny Glycoscience Laboratory and the Institute for Pheromone Research at Indiana University, and also a published author. Milos Novotny received his Bachelor of Science from the University of Brno, Czechoslovakia in 1962. In 1965, Novotny received his Ph.D. at the University of Brno. Novotny also holds honorary doctorates from Uppsala University, Masaryk University and Charles University, and he has been a major figure in analytical separation methods. Novotny was recognized for the development of PAGE Polyacrylamide Gel-filled Capillaries for Capillary Electrophoresis in 1993. In his years of work dedicated to analytical chemistry he has earned a reputation for being especially innovative in the field and has contributed a great deal to several analytical separation methods. Most notably, Milos has worked a great deal with microcolumn separation techniques of liquid chromatography, supercritical fluid chromatography, and capillary electrophoresis. Additionally, he is highly acclaimed for his research in proteomics and glycoanalysis and for identifying the first mammalian pheromones.
