Stephen E. Calvert
Stephen E. (Steve) Calvert, PhD, FRSC (born December 30, 1935) is a professor emeritus at the University of British Columbia. He has specialized in the study of chemical and geochemical oceanography. His work has shed light on the factors responsible for the wide compositional variability of marine sediments, the controls on organic matter burial and nutrient utilization in the ocean. Calvert utilizes a combination of organic, inorganic and stable isotopic information to reconstruct past sea surface temperatures, plankton production, terrestrial sediment supply and transport modes, nutrient utilization and bottom water oxygen concentrations. Early life and career Calvert was born in London, England in 1935. He studied at the University of Reading, obtaining a bachelor of science degree in 1958. Later, he emigrated to Canada, where he received his Ph.D. from Scripps Institution of Oceanography in 1964. Calvert is also a member of the UCSD Alumni Association. Currently, Calvert ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Stable Isotope
The term stable isotope has a meaning similar to stable nuclide, but is preferably used when speaking of nuclides of a specific element. Hence, the plural form stable isotopes usually refers to isotopes of the same element. The relative abundance of such stable isotopes can be measured experimentally (isotope analysis), yielding an isotope ratio that can be used as a research tool. Theoretically, such stable isotopes could include the radiogenic daughter products of radioactive decay, used in radiometric dating. However, the expression stable-isotope ratio is preferably used to refer to isotopes whose relative abundances are affected by isotope fractionation in nature. This field is termed stable isotope geochemistry. Stable-isotope ratios Measurement of the ratios of naturally occurring stable isotopes (isotope analysis) plays an important role in isotope geochemistry, but stable isotopes (mostly hydrogen, carbon, nitrogen, oxygen and sulfur) are also finding uses in ecological ...

Oceanographic Research Papers
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations o ...

American Geophysical Union
The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people (not members). AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C. History The AGU was established in December 1919 by the National Research Council (NRC) to represent the United States in the International Union of Geodesy and Geophysics (IUGG), and its first chairman was William Bowie of the United States Coast and Geodetic Survey (USCGS). For more than 50 years, it operated as an unincorporated affili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Association Of Canada
The Geological Association of Canada (GAC) is a learned society that promotes and develops the Geology, geological sciences in Canada. The organization holds conferences, meetings and exhibitions for the discussion of geological problems and the exchange of views in matters related to geology. It publishes various journals and collections of learned papers dealing with geology. History On February 14, 1947, a group of geologists met in Toronto with the objective of creating the Geological Institute of Canada, an association of geologists with the purpose of promoting, discussing and disseminating geological knowledge. Later that year a preliminary Constitution and Bylaws were approved and the first Councillors were elected. The organization's name was changed to the Geological Association of Canada. The group initially began with 140 charter members. The Association was designed to bridge the gap between the perceived industrial mineral orientation of the Geological Division of t ...
