Planktology
Planktology is the study of plankton, various small drifting plants, animals and microorganisms that inhabit bodies of water. Planktology topics include primary production, energy flow and the carbon cycle. Plankton drive the "biological pump", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to the ocean's depths. Such processes are vital to carbon dioxide sinks, one of several possibilities for countering global warming. Modern planktology includes behavioral aspects of drifting organisms, engaging modern ''in situ'' imaging devices. Some planktology projects allow the public to participate online, such as the Long-term Ecosystem Observatory. There are a very large number of, often closely related or similar looking, plankton species which makes classification a challenge for scientists. Their habitat also adds challenges to their study.

Plankton
Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. fresh water, Freshwater plankton are similar to marine plankton, but are found in lakes and rivers. Mostly, plankton just drift where currents take them, though some, like jellyfish, swim slowly but not fast enough to generally overcome the influence of currents. Although plankton are usually thought of as inhabiting water, there are also airborne versions that live part of their lives drifting in the at ...

Victor Hensen
Christian Andreas Victor Hensen (10 February 1835 – 5 April 1924) was a German zoologist and marine biologist (planktology). He coined the term ''plankton'' and laid the foundation for biological oceanography and quantitative studies. Family Hensen was born in the town of Schleswig, Schleswig-Holstein, Schleswig where his father ran a school for the deaf and dumb. His mother Henriette Caroline Amalie was the daughter of physician Carl Ferdinand Suadicani who founded an asylum in Schleswig. Hensen had eight sisters and five brothers including from his father's first marriage. Education and work Hensen went to school in Schleswig from 1845 to 1859 and then joined a grammar school in Glückstadt (Holstein) after which he joined to study medicine at the universities of University of Würzburg, Würzburg, Humboldt University of Berlin, Berlin (studying under Johannes Peter Müller, Müller) and University of Kiel, Kiel. In 1859, he received his doctorate in Kiel for a thesis on e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Oceanography
Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system. Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is ''Oikos'' (oικoσ), meaning ‘house’ or ‘habitat’ in Greek. With that in mind, it is of no surprise then that the main focus of biological oceanography is on the microorganisms within the ocean; looking at how they are affected by their environment and how that affects larger marine creatures and their ecosystem.Lalli, Carol M., and Timothy R. Parsons. "Introduction." Biological Oceanography: An Introduction. First Edition ed. Tarrytown, New York: Pergamon, 1993. 7-21. Print. Biological oceanography is similar to marine biology, but is different because of the perspective used to study the ocean. Biological oceanography takes a bottom-up approach (in terms of the food web), while marine biology studies the ocean from a top-down ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many scientific classification, phyla, family (biology), families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment (biophysical), environment rather than on taxonomy (biology), taxonomy. A large proportion of all life, life on Earth lives in the ocean. The exact size of this "large proportion" is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world, covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean.

Johannes Krey
Johannes is a Medieval Latin form of the personal name that usually appears as "John" in English language contexts. It is a variant of the Greek and Classical Latin variants (Ιωάννης, '' Ioannes''), itself derived from the Hebrew name '' Yehochanan'', meaning "YHWH is gracious". The name became popular in Northern Europe, especially in Germany because of Christianity. Common German variants for Johannes are ''Johann'', ''Hannes'', '' Hans'' (diminutized to ''Hänschen'' or ''Hänsel'', as known from "''Hansel and Gretel''", a fairy tale by the Grimm brothers), '' Jens'' (from Danish) and '' Jan'' (from Dutch, and found in many countries). In the Netherlands, Johannes was without interruption the most common masculine birth name until 1989. The English equivalent for Johannes is John.

Sayed ElSayed
''Sayyid'' is an honorific title of Hasanid and Husaynid lineage, recognized as descendants of the Islamic prophet Muhammad through his daughter Fatima and Ali's sons Hasan and Husayn. The title may also refer to the descendants of the family of the Bani Hashim through the Prophet’s great-grandfather Hashim, and others including Hamza, Abbas, Abu Talib, and Asad ibn Hashim. Etymology A few Arabic language experts state that it has its roots in the word ''al-asad'' , meaning "lion", probably because of the qualities of valor and leadership. The word is derived from the verb sāda, meaning to rule. The title seyyid/sayyid existed before Islam, however not in light of a specific descent, but as a meritocratic sign of respect. Hans Wehr's ''Dictionary of Modern Written Arabic'' defines seyyid as a translation for master, chief, sovereign, or lord. It also denotes someone respected and of high status. In the Arab world, ''sayyid'' is the equivalent of the English word "lie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
