Nils Jerlov
Nils Gunnar Jerlov (1909–1990) was a Swedish oceanographer, physicist, scientist, and researcher who studied how light interacts with water. He was a scientist in the field of ocean optics, and his water types are used to define the color and characteristics of natural water bodies. Biography Nils Jerlov was born October 12, 1909, in Bosjokloster parish in what was then Malmöhus County, Sweden. Nils Jerlov was the son of David Johnson and Hilma Henriksson. He was the nephew of Sigbert and Emil Jerlov. Jerlov attended the University of Lund, University of Lund, Sweden. He received a Master of Philosophy in 1932 and graduated with a Ph.D. in 1939. During that time, he became an assistant at the Swedish Hydrographic-Biological Commission in 1935 and worked in a laboratory there. In 1949 he married Elwi Galeen (1913–2008), the daughter of German director Henrik Galeen and his Swedish wife Elvira Adler. Jerlov became an associate professor of oceanography at the University of Go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malmöhus County
Malmöhus County () was a county of Sweden from 1719 to 1996. On 1 January 1997 it was merged with Kristianstad County to form Skåne County. It had been named after Malmöhus, a castle in Malmö, which was also where the governor originally lived. History Malmöhus County was part of Skåne province which was controlled by Denmark until 1658. In 1657, Denmark declared war on Sweden, while Sweden was at war with Russia, Poland, and Austria. Swedish forces were sent immediately from Poland to Denmark. Denmark was defeated which required the transfer of Skåne, Halland, Blekinge and Bohuslän provinces to Sweden under the Treaty of Roskilde. Denmark attempted to regain the lost provinces until 1710, but was unsuccessful. Geography Malmöhus County was part of Scania province situated on a peninsula that projects into the Baltic Sea on the northeast of the Öresund straits. The geography differs in many aspects from the rest of Sweden. The coastal regions typically have flat san ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optical Physicists
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light, however complete electromagnetic descriptions of light are often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that ...

Ocean Optics
Ocean optics is the study of how light interacts with water and the materials in water. Although research often focuses on the sea, the field broadly includes rivers, lakes, inland waters, coastal waters, and large ocean basins. How light acts in water is critical to how ecosystems function underwater. Knowledge of ocean optics is needed in Water remote sensing, aquatic remote sensing research in order to understand what information can be extracted from the Color of water, color of the water as it appears from satellite sensors in space. The color of the water as seen by satellites is known as ocean color. While ocean color is a key theme of ocean optics, optics is a broader term that also includes the development of underwater sensors using optical methods to study much more than just color, including ocean chemistry, particle size, imaging of microscopic plants and animals, and more. Key terminology Optically deep Where waters are “optically deep,” the bottom does not refle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Color
Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. This field of study developed alongside water remote sensing, so it is focused mainly on how color is measured by instruments (like the sensors on satellites and airplanes). Most of the ocean is blue in color, but in some places the ocean is blue-green, green, or even yellow to brown. Blue ocean color is a result of several factors. First, water preferentially absorbs red light, which means that blue light remains and is reflected back out of the water. Red light is most easily absorbed and thus does not reach great depths, usually to less than 50 meters (164 ft). Blue light, in comparison, can penetrate up to 200 meters (656 ft). Second, water molecules and very tiny particles in ocean wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Of Water
The color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of blue light. Dissolved elements or suspended impurities may give water a different color. Intrinsic color The intrinsic color of liquid water may be demonstrated by looking at a white light source through a long pipe that is filled with purified water and closed at both ends with a transparent window. The light sky blue color is caused by weak absorption in the red part of the visible spectrum. Absorptions in the visible spectrum are usually attributed to excitations of electronic energy states in matter. Water is a simple three-atom molecule, H2O, and all its electronic absorptions occur in the ultraviolet region of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Oceanography Society
The Oceanography Society (TOS) is a nonprofit society founded in 1988, based in Rockville, Maryland, U.S. and incorporated in the District of Columbia. It is an oceanographical organization that aims to promote communication among oceanographers, spread knowledge through research and education, and to provide a constituency for building consensus amongst the sub-disciplines of the field. The society publishes the scientific journal ''Oceanography'', which publishes articles on all oceanic disciplines. History The idea for forming an oceanographic society was hatched by a group of scientists, who approached both the American Geophysical Union and the American Meteorological Society with the idea. The two groups both responded positively, leading to several oceanographic events at the time. However, the need developed for the creation of an independent community, resulting in the formation of the Oceanography Society in March 1988. These early developments by the society were par ...

Climate Modeling
Numerical climate models (or climate system models) are mathematical models that can simulate the interactions of important drivers of climate. These drivers are the atmosphere, oceans, land surface and ice. Scientists use climate models to study the dynamics of the climate system and to make projections of future climate and of climate change. Climate models can also be qualitative (i.e. not numerical) models and contain narratives, largely descriptive, of possible futures. Climate models take account of incoming energy from the Sun as well as outgoing energy from Earth. An imbalance results in a change in temperature. The incoming energy from the Sun is in the form of short wave electromagnetic radiation, chiefly visible and short-wave (near) infrared. The outgoing energy is in the form of long wave (far) infrared electromagnetic energy. These processes are part of the greenhouse effect. Climate models vary in complexity. For example, a simple radiant heat transfer model tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
